Astonishing Hearing Loss Facts and Data

October 26, 2013 By Leave a Comment

Do you have a family member or friend that needs a hearing aid (or at least a hearing test) but won’t go along with your suggestions? Chatting about some of the statistics related to the prevalence, causes and effects of hearing loss may finally get them to make that initial appointment. These facts and stats could help you persuade someone you care about that it is time to schedule a hearing evaluation:

  • The number of Americans with hearing loss has doubled in the last 3 decades.
  • More men than women experience hearing loss.
  • Approximately 36 million people in the United States have some sort of hearing loss, which is almost one out of every five people.
  • Roughly 13% of the population over age 65 will experience tinnitus – ringing in the ears.
  • Many more people could benefit from a hearing aid than in fact wear one. Some estimates say there are 4 additional people who could benefit, for every 1 actually using a hearing aid.
  • Ten million people have permanent loss of hearing due to noise, and 30 million more are exposed to dangerous noise levels every day.
  • Close to 13,000 adults and 10,000 children in the US have cochlear implants.
  • Research studies have indicated that those with hearing loss experience it as mild in 65% of cases, moderate in 30% of cases and severe in 5% of cases.
  • High frequency hearing loss caused by recurring loud noise exposure affects about 26 million people in the US (ages 20-69). This includes regular noise exposure from both work and leisure sources.
  • People with hearing loss wait close to a decade before doing anything about it. Don’t let this be you or someone you love!

Overview of the 5 Primary Forms of Hearing Loss

October 19, 2013 By Leave a Comment

Hearing loss is labeled in a variety of ways. The exact part of the auditory pathway affected determines the categorization. The hearing loss may be conductive, senorineural, central, functional or mixed. Certain forms of hearing impairment are more treatable than others, and a trained hearing care specialist will be able to show you your choices after an initial evaluation.

Conductive hearing loss – In situations where sound waves are not adequately conducted to the interior of the ear through the parts of the outer and middle ear, conductive hearing loss arises. This is very common and can be due to a buildup of ear wax, a buildup of moisture in the eustacian tube, which keeps the eardrum from moving properly, a middle ear infection, a perforated eardrum, disease of the tiny bones of the middle ear and other obstructions in the ear canal.

Most instances of this type of hearing loss are reversible, assuming there isn’t any irreversible damage to the structures of the middle ear, and with proper treatment the issue usually resolves fairly quickly. In some cases a surgical procedure can help to correct the condition or a hearing aid may be fitted.

Sensorineural hearing loss – This type of hearing loss accounts for more than 90% of the situations in which a hearing aid is worn. Sensorineural hearing loss is the result of damage in the interior of the ear or damage to the acoustic nerve, which keeps sound signals from being transmitted to the brain. Also known as nerve deafness or retrocochlear hearing loss, the damage is more often than not permanent, although improvements in modern technology have made it possible for some previously untreatable cases to see some improvement.

The most common reasons behind sensorineural hearing loss are the aging process, prolonged exposure to noise, complications with blood flow to the inner ear, fluid disturbance in the inner ear, drugs that cause injury to the ear, some diseases, genetics and issues with the auditory nerve.

Hearing aids are adequate for the majority of people that have this kind of hearing loss, but in more serious cases, a cochlear implant can help bring back hearing to those individuals for whom a typical hearing aid is not enough.

Functional hearing loss – An infrequent occurrence, functional hearing loss is not physical. This condition is due to an emotional or psychological condition in which the person’s physical hearing is normal, but they are not able to hear.Central hearing loss – This condition occurs when a problem in the CNS (central nervous system) keeps sound signals from being processed and interpreted by the brain. Affected individuals can seemingly hear just fine, but cannot decode or decipher what the speaker is saying. Numerous cases involve a problem with the person’s capacity to adequately filter rivaling sounds. For example, most of us can hold a conversation while there is traffic noise in the background, but people with central hearing loss have a difficult time doing so.

Mixed hearing loss – As suggested by the term, mixed hearing loss is a mixture of multiple types of hearing loss – conductive and sensorineural hearing loss. Though there are a couple of other types of hearing loss, the combination of these two is most common.

Fact or Fiction – Surplus Ear Wax Leads to Loss Of Hearing

October 12, 2013 By Leave a Comment

What we call ear wax develops because our ear canals are covered with hair follicles and glands that generate an oily wax called cerumen. The reason for this wax is to line the inner surface of the ear canal and protect it by gathering up bacteria, dirt and dust, and miroorganisms. Ear wax also helps to prevent irritation when the sensitive skin of the ear canal is exposed to moisture; Thus, the production of ear wax is both natural and healthy.

In the majority of people, ear wax ultimately makes its way to the outer areas of the ear, where it either falls out or is rinsed away when we clean our ears. However, the glands in certain people’s ears generate more wax than usual. Because of this, the wax builds up and may harden, blocking the ear canal and preventing sound waves from getting to your inner ear. The accumulation of ear wax is one of the most widespread causes of hearing loss, in people of any age.

The signs and symptoms of a blockage caused by excess ear wax include feeling as if your ears are clogged up, hearing a ringing noise (tinnitus), and a partial loss of hearing, which becomes worse over time. This is a type of conductive (as opposed to sensorineural) hearing loss, where the sound waves are blocked from reaching the eardrum. Thankfully, this grounds for hearing loss is easily identified and remedied.

If the signs and symptoms in the list above sound familiar to you, see us in our clinic where any of our team members can perform pain-free assessments to see whether you do indeed have an excess accumulation of ear wax. If it is, an excessive buildup of ear wax is readily treated, either at home or at the clinic.

If a hearing specialist says that you have excess ear wax that is obstructing your ear canal, you can take steps to remove it yourself in your own home. Do not attempt to use a Q-tip, which can cause the ear wax to become even more compacted. Instead, add a few drops of baby oil, glycerin, mineral oil, or commercial ear drops designed for this purpose to each ear, let them remain in the ear for a couple of minutes to loosen up the wax, and then rinse the loosened wax out, using water at body temperature. (Note: using either hot or cold water to flush your ears can lead to feelings of vertigo or dizziness.) Pharmacies sell small bulb-like syringes that can be used to flush the ear after the wax has been loosened, aiding the process. Two more things not to do are to 1) use a jet irrigator like a WaterPik because its spray is too powerful and might cause damage to your eardrums, and 2) use any kind of irrigation at home if you know for sure that you have a punctured eardrum.

If these home remedies don’t seem to clear up the blockage, call or visit us for assistance.

Linking Foods and Nutrients to Hearing Losses

September 30, 2013 By Leave a Comment

The majority of us have been advised to eat our carrots for excellent eye sight. Chances are that you didn’t hear any similar tips about what foods were good for your ears and hearing. Now we can tell our little ones what to eat for healthy ears and hearing, and also sensible for us to follow our own advice!

Several things may cause hearing impairment, including infections, age and noise. Nutrients that may help prevent certain of hearing loss are contained in the food described below.

Surprisingly, fish like trout or salmon which contains vitamin D and omega 3 fats, has been demonstrated in studies to reduce age-related hearing loss. Other good vitamin D and omega 3 sources are the anchovies on your pizza and the tuna fish probably sitting in your cupboard. For a hearing boost in old age, eat any one of these at least two times per week.

Workers subjected to loud noise at work, for example music artists or heavy equipment operators, are at a elevated risk for ear damage. People with a job or pastime exposing them to intense noise, can help protect their hearing with bananas, potatoes, artichokes, or any other foods abundant in magnesium. Scientific studies have found that foods rich in magnesium help defend against noise-induced hearing loss (NIHL). The mechanism for how the magnesium does this is not known, but the end result has been seen in animals and humans.

Noise exposure can provoke the generation of destructive free radicals which are linked to the demise of delicate inner ear hair cells. Reduce free radical damage with folic acid and antioxidants. Common foods that are rich in both folic acid and antioxidants include spinach, eggs, asparagus and nuts.

You’ll be pleased to learn that dark chocolate is beneficial to your hearing health! The zinc contained in dark chocolate aids in preventing zinc deficiencies which are connected to age-related hearing loss. If you don’t enjoy dark chocolate, eat some oysters on the half shell; any foods that contain zinc will work!

Along with encouraging our children to consume carrots for good eye sight, now we can teach them to protect their hearing and minimize possible hearing problems with specific food suggestions.

Tips for Cleaning Your Own Ears and Dissolving Ear Wax the Right Way

September 23, 2013 By Leave a Comment

Having trouble hearing? Probably the most common cause of short-term hearing loss is an accumulation of ear wax within the ear canal. If you’re reasonably certain that ear wax is the resource for your short-term hearing loss, you most likely want to clean your ears. The question is how to do this safely, and without causing damage to the delicate tissues of your ear or your ability to hear.

It is best to get started with a few reminders on what not to do when cleaning your ears. Never stick any physical objects in your ear. Whether it’s a cotton swab or other tool, you’re more likely to make the problem worse by further compressing the ear wax if you go poking around in your ear. One more thing you should never do is attempt to use any product that shoots water under pressure directly into your ears; to do this risks rupturing your eardrums. Last but not least, if you know that you have a ruptured eardrum, leave cleaning your ears to a hearing specialist. The same holds true if you think you have an ear infection. Indications of ear infections include ear pain, fever, fluid draining from the ears and vomiting or diarrhea.

To clean your own ears safely and gently in your own home, all you need is a syringe or bulb, available from any drug store, and a rinse solution. You can buy a carbamide peroxide solution at the local drugstore, or make your own solution by combining equal measures of 3-4%, mineral oil and glycerin.

To make use of the carbamide peroxide solution, carefully squeeze the solution into the ear with the bulb or syringe. It works best to lay on your side and have a towel readily available to catch drips. Try to avoid touching the ear with the syringe or bulb if you can. Keep the solution in each ear for a few minutes allowing it time to work on dissolving the wax.

After this rinse solution has softened and loosened the ear wax, flush your ears with lukewarm water, and then dry your ears thoroughly with a towel, being careful not to stick it into the ear canal. You can repeat this procedure twice daily for 2-3 days if your ears still feel obstructed. If the situation continues, speak with an audiologist or hearing specialist for assistance.

Treatment Protocols for People with Central Auditory Processing Disorder/CAPD

September 16, 2013 By Leave a Comment

There are many good reasons why Central Auditory Processing Disorder, or CAPD, is hard to diagnose accurately. The problem is not because the children cannot hear words and phrases being spoken to them, but because their brains have an inability to interpret the words and grasp their meaning, which implies that conventional hearing tests do not always identify CAPD. One more reason it is difficult to diagnose is because kids often acquire complex coping behaviors. These children can be experts at using expressions or reading lips to hide their problem.

These particular characteristics of CAPD also make treatment of the disorder tricky, because any individual wanting to enhance the child’s speech comprehension must constantly be aware of them and look for ways to work around them. Unfortunately there is no definitive cure or therapy for CAPD that works consistently well across all kids. Each therapy plan is highly individualized and crafted based on the patients’ limitations. With that being said, there are a variety of treatment protocols that may greatly enhance the developmental abilities of children with Central Auditory Processing Disorder.

CAPD therapy falls into 3 broad categories: direct treatment, environmental change and compensatory strategies.

  • Direct Treatment – Direct treatment refers to the use of computer-assisted learning and 1-on-1 sessions to make the most of the brain’s natural plasticity, its capacity to transform itself, and establish new ways of processing and thinking. These kinds of techniques include the use of the “Fast ForWord” educational software from Scientific Education or Hasbro’s “Simon” game to improve kids’ capacity to discriminate, order, and process the sounds they hear. Some therapists use dichotic training to cultivate the childrens’ ability to hear multiple sounds in different ears and process them the right way, while others use the “Earobics” program by Houghton Mifflin Harcourt to improve phonological awareness.
  • Environmental Change – In the category of environmental change one strategy is lowering the quantity of ambient noise via soundproofing and putting in acoustic tiles, wall hangings or curtains because background noise is proven to make it more difficult for an individual with CAPD to comprehend speech. Increasing the volume of selective voices in the classroom is also helpful; the instructor wears a microphone and the CAPD pupil wears a tiny receiver that enhances the instructor’s voice to make it more distinguishable from other sounds or speakers. One more environmental modification is better lighting. A well lit face is a lot easier for a person with Central Auditory Processing Disorder to “read” for cues.
  • Compensatory Strategies – Approaches that focus on helping the CAPD learners to improve their attention, memory, language and problem-solving skills are commonly called compensatory strategies. These strategies give pupils enhanced coping skills and techniques that enable them to succeed at learning, and also make them learn to take responsibility for their own academic progress. Techniques and strategies of this type consist of drills in solving word problems and active listening.

The overall message is that treatments are available if your child is diagnosed with CAPD, but remember that step one is properly diagnosing the condition, and doing this as early as possible. Keep in mind that our skilled hearing expertshearing experts are here to assist you in any way possible and to point you to other trusted area experts for the best CAPD diagnostic and therapy choices.

What Size of Battery Does My Hearing Aid Require?

September 9, 2013 By Leave a Comment

Unfortunately, there is no simple answer to the question “What kind of battery does my hearing aid need?” because hearing aid models and the batteries that power them common in many varieties. The simplest scenario to deal with is if you currently own a hearing aid; if that’s the case, read the owner’s manual that was included with the device or get in touch with the professionals who fit it for you to verify the correct battery type. In the event that you don’t use a hearing aid yet and are looking to decide which type and model is best for you, do a little research to help you decide. Hearing aid batteries vary greatly in price, and in battery life, so your selection of hearing aid can affect the amount of money you spend over time to use it.

To make things easier for consumers, hearing aid producers and those who make the batteries for them have developed a standardized color coding system to make them easier to find. No matter who the maker is, hearing aid batteries of a specific type and size will always have the identical color code on their packages.

The primary battery sizes and types to be aware of are:

Size 13 / Orange – Hearing aid batteries with a color code of orange are Size 13, and fit Behind-the-Ear (BTE) and In-the-Ear (ITE) types of hearing aids; their battery life is normally around 240 hours.

Size 312 / Brown – A brown color code indicates a Size 312 battery, generally used in In-The-Ear (ITE) and In-The-Canal (ITC) styles of hearing aids; because of their smaller size they generally have battery life of 175 hours.

Size 10 / Yellow – Yellow indicates Size 10 batteries. Size 10 are the smallest and most abundant type of hearing aid battery with a typical battery life of 80 hours. This size of battery is commonplace in Completely-In-Canal (CIC) and In-The-Canal (ITC) hearing aids.

Size 675 / Blue – The blue color code always identifies Size 675 batteries, which are often used in cochlear implants and larger Behind-The-Ear (BTE) style hearing aids; the 675 batteries have an average life of 300 hours.

These are the most popular types and sizes of hearing aid batteries, but there are hearing aids that call for alternative ones. If yours need one of these alternate types, most merchants that sell batteries can order them for you.

Be sure to read your owner’s manual carefully before purchasing bulk quantities of hearing aid batteries. If your unit uses rechargeable batteries, you will only need disposable batteries for emergencies. Furthermore, remember to always store your hearing aid batteries at room temperature in their sealed packages to make sure that they keep their full charge.

An Overview of Ruptured Eardrums: Prevention, Symptoms and Treatment

August 27, 2013 By Leave a Comment

Eardrums are important, playing two vitally important roles in hearing. First they vibrate in response to sound waves. Second they create a barrier that safeguards the inner ear from infection. If your eardrum is fully intact, your inner ear is a safe and sterile environment; but once it has been punctured or torn, microbes can enter and cause a serious infection generally known as otitis media.

The terms ruptured eardrum and perforated eardrum mean the same thing. They both reference a condition whose technical name is a tympanic membrane perforation where there is a puncture or tear in the very thin membrane we know as the ear drum. There a variety of ways that an eardrum may become perforated, the most common of which is an ear infection where the resulting buildup of fluid pushes against the eardrum until it tears. Some people perforate their own eardrums by inserting foreign objects into the ears, for example the use of cotton swabs to remove ear wax. Barotrauma is yet another potential cause of a punctured ear drum. When the pressure inside the ear is very different than the pressure outside the ear – lower or higher – the eardrum may not be able to withstand the pressure difference and ruptures. Flying and scuba diving are a couple of occasions where this is prone to occur. Loud noises and explosions can also cause perforated ear drums. This phenomenon is known as acoustic trauma.

Indications of perforated eardrums include:

  • Pain in the ear
  • Loss of hearing in the affected ear
  • Vertigo or dizziness
  • Fluid draining from the ear

If you encounter any of these signs and symptoms, see a hearing health provider, because if the eardrum is ruptured, immediate and correct treatment is important to prevent hearing damage and infection. Untreated, a ruptured eardrum can result in middle and inner ear infections, middle ear cysts (cholesteatoma), and permanent hearing loss.

At your appointment the specialist will view the eardrum with an instrument called an otoscope. Because of its internal light, the otoscope gives the doctor a clear look at the eardrum. Perforated eardrums generally heal on their own in 8 to 12 weeks. During this time period, your healthcare provider will most likely advise you to avoid diving and swimming and to refrain from blowing your nose as much as possible. It’s also advisable to avoid any non-essential medications. If the puncture or tear is close to the edge of the eardrum, the health care provider can help the healing process by placing a temporary dam or patch to help reduce the risk of infection, or even propose surgery.

Any remaining pain or discomfort can be handled using over-the-counter (OTC) pain medications such as acetaminophen or ibuprofen. Not every perforated eardrum can be prevented, but there are things you can do to reduce your risk. Always get immediate treatment for any ear infections and never put any foreign objects into your ear (even for cleaning).

On-the-Job Noise-Induced Hearing Impairment: Professions With Greater than Average Risk

August 20, 2013 By Leave a Comment

Could your job be contributing to your hearing impairments? Extreme noise levels are one of the most common causes of hearing damage. Worrying about your ability to hear is a natural response for anyone working at a high-noise profession.Approximately 30 million employees are at risk of hazardous noise exposure on the job according to the Centers for Disease Control.Workers in high-noise job areas must equip themselves with the specifics of occupational hearing safety and keep an open conversation with their companies.

All employees should assess their own work surroundings for high-noise levels, especially anyone in the following jobs.

  • Manufacturing – The largest number of permanent hearing losses suffered in the workplace are in manufacturing. Manufacturing industries routinely expose workers to machinery and equipment which generates upwards of 90 decibels of noise for extended period of time.
  • Construction – Construction workers rank next to the highest for permanent hearing loss disabilities suffered in the workplace. Construction equipment routinely exposes staff to heavy machinery that produces over 90 decibels. A Washington State study of construction workers discovered that in spite of being exposed to noises exceeding 85 decibels during 70 percent of their shifts, construction workers only wore ear protectors 20% of the time (or less).
  • Chemicals Industry – Exposure to certain substances (especially those that contain n-butyl alcohol, toluene, lead and carbon monoxide) has been connected to increased hearing loss by itself. These particular chemicals now known to combine with noise to cause increased hearing loss.
  • Miners – According to the Center for Disease Control, 49 percent of male miners are expected to have a hearing impairment before age 50 – versus 9 percent of the general population – rising to 70% by age 60.
  • Motorcycle Courier – Research into motorcycle noise – with and without helmets – under various driving conditions at speeds between 45 mph to 65 noted that the noise measured ranged from 70 decibels to 128 decibels.
  • DJs and Nightclub Staff – Everyone that works in a nightclub – security, wait staff, bartenders – is at risk, not just the musicians. In a controlled research study, noise levels of up to 108 decibels were recorded in the nightclubs. The average noise level for a typical nightclub outing was 96 decibels which is over the noise level at which the provision of hearing protection is required for employers in industry. The study concluded that Disc Jockeys are at substantial risk of developing noise-induced hearing loss and sound exposure in nightclubs frequently exceeds safe levels.
  • Musicians – Across practices, studio recording and performances, musicians are constantly engulfed in sound. The list of famed music artists with permanent hearing problems or tinnitus keeps growing each and every year. Well known artists on the current list include Ozzy Osbourne, Neil Young, Phil Collins, George Martin, Jeff Beck, Eric Clapton, and Ludwig van Beethoven.
  • Band & Orchestra – A study on the noise exposures of classical musicians experienced during both performances and rehearsals found that the brass section averaged 95 decibels while the strings and brass section averaged 90 decibels. Top volumes were 130 decibels in the percussion and brass sections. A different Swedish research project showed that 59 out of 139 orchestra musicians had hearing losses greater than that normal for their ages.
  • Airport Staff – The noise of an airplane engine is one of the loudest auditory occupational hazards, with noise levels at a shocking 140 decibels.
  • Firefighters and Paramedics – All those sirens squealing add up over time. Several research studies have examined the frequency of hearing disabilities in firefighters and emergency vehicle drivers with most concluding that firefighters suffer increased hearing loss relative to the general public of the same age.
  • Military – Noise-induced hearing loss is the number one disability among US military personnel. According to the Deafness Research Foundation, over 65 percent of combat troops returning from Afghanistan are afflicted by noise-induced hearing loss.
  • Plumbers – The CDC website states that 48% of plumbers reported that they had a perceived hearing loss.

Essential List of Hearing Aid Types and Acronyms

August 13, 2013 By Leave a Comment

Shopping for hearing aids can be difficult if you are not familiar with the many abbreviations used to describe common styles. This collection includes the majority of the acronyms you’ll come across when looking for hearing aids and presents a short explanation of each. The ideal approach to truly understand the differences is to see them in real life, therefore if some of these descriptions are not clear, you should contact us to visit and check out the various types.

What follows is a list from smallest to largest of standard hearing aid styles

  • Invisible in Canal (IIC) – The IIC type of hearing aid fits fully inside the ear canal and is fully invisible from the outside. Invisible-in-Canal types are generally not suggested for the elderly, yet are an excellent choice in middle age.
  • Completely in Canal (CIC) – Appropriate for mild to moderate hearing losses, the CIC design fits inside the ear canal making it nearly invisible. Because of its small size, the CIC design may have fewer features. For example, the Completely in Canal style doesn’t have space for directional microphones.
  • In the Canal (ITC) – Appropriate for mild to moderately-severe hearing losses, the ITC design is a compact hearing aid which fits inside the ear canal and is visible from the outside. Because it is slightly larger than the models which fit deeper in the ear canal, directional microphones are possible with the In-the-Canal style.
  • In the Ear (ITE) – Suitable for mild to severe hearing losses, the ITE design of hearing aid is a good choice for numerous hearing losses and is very easy to handle. The ITE is visible inside the ear, but its greater size offers more features, additional power and a superior battery life.
  • Half Shell (HS) – Appropriate for mild to severe hearing losses, the Half Shell is a custom molded hearing aid that fits inside the ear canal and is partially visiblefrom the outside. Being somewhat larger than the styles which fit further into in the ear canal, added benefits such as directional microphones are feasible with the Half Shell style.
  • Receiver In the Ear (RITE) or (RIE) – Appropriate for mild to moderately-severe hearing losses, the Receiver In the Ear design is the smallest among the hearing aids work externally. The Receiver In the Ear type combines a tiny case that fits behind the ear and a receiver placed inside the ear connected by a flexible tube. The ear canal stays open for natural sound quality.
  • Open Ear / Open Fit – Appropriate for mild to moderately-severe hearing losses, the Open Ear (also called Open Fit) model combines an exterior hearing aid case that rests behind the ear and a clear tube inserted into the ear. The Open Ear/Open Fit design leaves the ear canal open for natural sound quality and is available in various colors.
  • Behind the Ear (BTE) – Appropriate for mild to severe hearing losses, the BTE hearing aid’s larger case allows for many advanced features and is a superior choice for anybody with poor finger dexeterity. All of the component parts are inside the external case which is worn behind the ear. BTE hearing aids come in many colors. This design is often chosen for young children for growth and safety reasons.
