How Technology is Changing Hearing Aids?

Hearing device technology has improved a lot over the last few decades. Still, at the end of the day, hearing aids always have been manufactured and designed to have four main components:

  • Microphone
  • Receiver
  • Processor
  • Power source.

The process is simple- the microphone receives the sounds in an environment and transports them to the device’s processor.

It then enhances the entire signal and transports it to the device’s receiver.  The receiver then delivers this new amplified signal right into your ear canal. The battery drives the entire process.

Hearing device technology can either be considered primary or advanced, entirely based on what kind of  processor it has.

Moreover, even today’s straightforward and basic digital hearing devices offer far more convenience than the top-notch hearing aids from back in the day. Even complicated problems like cookie bite hearing loss can be controlled with modern day hearing aids.

New Advancement of High-Tech Hearing Aids

As technology advances, digital hearing devices are offering a lot more features. They are also becoming more automatic.  This has the ability to help you communicate in challenging listening environments.

The following are some of the significant advancements of the hearing aids that changed the entire hearing aid industry.

Note: All advanced features mentioned below are unique to hearing devices and aren’t found in any personal hearing devices or amplifiers.

1.  Frequency Response and Sound Processing

Every hearing device processes noises and sound. This means when the sound enters the hearing device, it has to be categorized into different bands or channels of sound. It then gets digitized before the sound can get amplified.

The better the device, the more flexible it will be to channel sounds. For instance, you may only have hearing impairment in the higher frequencies. A top-notch hearing device can only amplify those particular sounds that fall within that frequency spectrum.

On the other hand, a lower-end model may only be able to amplify mid level and high level frequency sounds.

This entire customization is known as the frequency response.

2.   Bluetooth Compatibility

Bluetooth compatibility is actually a wireless characteristic that allows hearing devices to link to smartphones and any other devices with Bluetooth connectivity.

Bluetooth technology can improve the noise-to-signal ratio and even terminate feedback from the device’s microphone. This is because the sound evades the microphone and enters directly into the hearing device’s processor.

Even a Bluetooth link is less likely to undergo interference that can take place with an F.M. system.

3.   Artificial Intelligence (A.I.)

Some of the premium hearing devices come with A.I. (artificial intelligence) technology.  This allows them to have access to a deep neural connection that processes sound.

The best feature about A.I. in these devices is, it can start making changes by detecting the surrounding environment by program preferences and logging volume control settings.

By this time, a DNN will allow these hearing devices to start mimicking the sounds just like the way the brain would have done if you didn’t hear impaired.

4.   Rechargeable Batteries

The more advanced hearing aids are getting; the easier life is becoming for people with hearing issues. And rechargeable batteries are one of the vital examples of this!

It allows the user to stop pulling out those small button batteries now and then! Moreover, it is anticipated, all hearing devices will have rechargeable batteries within the next few years. This will help avoid the “frequent battery changing” issues.

5.   Tinnitus Masking Specialities

Most advanced hearing devices come along with tinnitus masking specialties. A hearing care expert or an audiologist can program these devices to emit noises that can easily cover or mask the ringing sounds in the ear, a.k.a. tinnitus.

6.   F.M. Compatibility

FM (Frequency modulation) compatibility is nothing but a wireless property that allows hearing devices to link with any F.M. systems. Sometimes this is done by using a special fitting to the hearing devices known as a boot.

F.M. systems can also be used with hearing devices or alone. Such as telecoil, F.M. systems also improve the noise-to-signal ratio without causing a loop in these devices.

F.M. compatibility is essential, especially when you are choosing hearing devices for your children. These particular systems are usually handed-down in educational systems. This is done to ensure the instructor or teacher’s voice is always heard above all the noises in the classroom.

7.   Digitized Noise Reduction

Digitized noise reductions can analyze the sound signals and determine whether it contains any unwanted noises or not. If any such noises are detected, the noise reduction system will automatically reduce the levels of excess noise.

This digital noise reduction feature eventually makes the environment or background sounds less annoying. Moreover, it slowly increases the listening comfort. This advanced noise reduction feature has indeed been one of the most preferred features of all.

Real-World Benefits of These Advanced Features

Just think about this scenario, you are in a busy restaurant having dinner with your family or friends. The environment can be very loud and noisy. People are talking or laughing, dishes are clanking against one another, and the waiters are running and rushing from table to table.

But fortunately, you are able to put on your new high-tech hearing devices. This will help simultaneously with reducing impulsive noises like spoons clanking on plates (impulse noise reduction).

It will even decrease any whirring sounds of the ventilators (digitized noise reduction), and suppress loud voices of people across the tables (directional microphone system).

All these benefits you’ll be getting together, and so, you can sit back down and relish the evening with your friends and family.  You will not face issues regarding unnecessary noises.

Honestly, it’s just a single example of high-tech hearing devices in action. This is how technology is changing hearing aids!!
