The full integration of Bluetooth tech into the routine functions of hearing aids has brought a wealth of new possibilities.
Due to the incorporation of higher computer functions into what used to be basically simple amplifiers, hearing aids are now yet another aspect of the Internet of Things (IoT). The interconnectivity that Bluetooth provides — by creating a small wireless network in which devices can communicate — allows hearing aids to connect to other machines nearby and, by extension, to the Internet via another device’s WiFi capabilities.
Bluetooth connections are stable and not dependent on a WiFi network’s strength. They work within only a small radius.
This is why it is now possible, using a dedicated app, to control a hearing aid’s functions with a smartphone or tablet. The ability Bluetooth affords for near-instantaneous interaction between the two devices means no more fumbling with tiny knobs or buttons on a hearing aid. It also allows for a far wider range of controls.
Likewise, sound can now be transmitted electronically directly to the hearing aid. The oh-so-annoying squeal that used to mark phone conversations with a hearing aid is a thing of the past. Anything one listens to from electronic sources — radios, televisions, listening devices — can now be streamed directly into hearing aids, resulting in much higher sound quality and the ability to avoid distractions from other sources of noise.
Finally, hearing aids can gather data on the sound dynamics of where you spend your time and how you use your hearing aids. This can then be uploaded — via the Bluetooth connection with your app, then from app to your hearing health provider via the Internet — and the data used to fine-tune your hearing aid for the future.
