Hearing aids have went through a large number of iterations in their 200-plus year history. The technology that is implemented in hearing aids has historically been developed by means of a devoted scientist who is either affected by hearing loss or has a friend or family member affected by hearing loss. As an example, Alexander Graham Bell’s mother had substantial hearing loss and his wife was deaf.

Here are 10 other little-known facts about hearing aids:

1. Hearing aids can be synced up with wireless devices through state of the art technology like Bluetooth, so users are able to enjoy direct signals from their smart phone, MP3 player, TV, and other gadgets.

2. Hearing aids are not one size fits all – in fact, they can and should be programmable. This means they have the capability to recall the most comfortable settings for the user, often readjusting in real time to the surrounding environment.

3. Digital hearing aids – a recent advancement — have drastically diminished the occurrence of pestering feedback, echoes, and background noises. These were par for the course as part of earlier technologies, and they made concentrating much harder.

4. In addition to the amplification of sound, modern hearing aids can also enhance and clarify sound.

5. When used in combination with special induction or hearing loops, hearing aid users can more clearly hear notices in public areas, meetings, airports, arenas, and other congested areas. This technology enhances sounds and minimizes all the background noise.

6. It used to be that hearing aids were only manufactured in beige and related colors to match people’s skin color, so that they were not easily recognizable. Today, users are welcoming their hearing aid technology, exhibiting a range of colors and patterns to show off their devices and stick out in a crowd.

7. Similarly, hearing aids are smaller in size than ever before. They used to be large, cumbersome gadgets that weighed several pounds and barely amplified sound. Today, they only weigh a few ounces and provide remarkably better sound quality.

8. Today, you can purchase water resistant and waterproof hearing aids to better fit in with your lifestyle. Water resistant hearing aids can tolerate low levels of humidity and moisture, while waterproof hearing aids can withstand higher levels of moisture during showering and even swimming.

9. Instead of having to frequently replace the batteries in hearing aids, many are now made with rechargeable technology to cut down on upkeep costs.

10. Hearing aids do much more than amplify sound – they can also contain special tinnitus therapy components that provide the user with relief when it comes to constant ringing in the ear.
