Hearing Aids: How They’ve Gotten Smaller and Smarter

Hearing aids are an integral device in society. They are the number one treatment method for hearing problems, ensuring that millions of people around the world can still listen to conversations and enjoy a higher quality of life. 

When first introduced, the hearing aid was a rather large device that was hard to hide. Consequently, it became a source of embarrassment for some people, leading to many individuals avoiding them and opting to live with untreated hearing loss. 

However, modern technology allows for substantial developments in the hearing aid field. Nowadays, some hearing aids that are almost invisible, yet are packed full of incredible features that older varieties could even dream of. How has this happened, and what’s made it possible?

New manufacturing technologies

The only problem with hearing aids is that they can be too bulky. It inconvenienced many, but modern manufacturing technologies are changing this. The need for physical impressions of someone’s ears is no longer required, due to modern scanning technologies combined with rapid 3D printing. 

The introduction of processes like microfabrication further enables small parts manufacturing to be possible. It’s allowed tiny electronic components to be created, meaning the outer shell of hearing aids can become smaller and smaller. 

Improvements in audio technology

Another significant reason for the reduction in hearing aid sizes is that audio technology has markedly improved. Before, large microphones and speakers needed to be included for the devices to work. Now, smaller microphones with clearer audio can be used, letting the entire device fit in a smaller package. 

There’s also something called binaural capability, which effectively means two hearing aids are wirelessly connected to one another. This means they can work with each other to create a better sound for the wearer. Again, using technology to improve the quality of these devices means there’s less need for additional parts, shrinking them down. 

The birth of the AI hearing aid

Arguably the biggest development in this space is the introduction of artificial intelligence in hearing aids. By using a combination of machine learning and AI, hearing aids can adapt and adjust to different settings and scenarios. 

The idea is that the device learns from your behaviors and the environments you’re in. For instance, if it detects a lot of background noise in an area, it can automatically adjust to blur out the sound and focus more on the voices closer to you. 

Hearing aids are also now Bluetooth compatible, meaning many settings can be altered via a smartphone app. Thus, the AI technology in these devices can learn from your settings and slowly begin to adapt to your listening habits. Having things like this ultimately does make the device smaller. There’s no need for parts to tune the hearing aid or alter the volume/settings. It can be done either automatically by AI, or via an app.

In conclusion, it’s clear how certain technologies and advancements have made hearing aids a lot smaller and smarter. These days, devices are available in a range of sizes – some of which can barely be seen. Instead of sacrificing features for size, modern hearing aids use technology to become more powerful and functional than ever before.
