Hearing Aid Technologies

Hearing aids have become very sophisticated over the years, with features undreamt of just a generation ago. Nowhere is this more apparent than in the advent of wireless connectivity. Thanks to the proliferation of Bluetooth® technology, today’s hearing devices are more versatile than ever, and feature unparalleled sound quality and convenience.

Wireless Technology and Hearing Devices (made-for-iPhone and other smartphones)

Bluetooth is a wireless communications system that allows a variety of electronic devices, including computers, smartphones and personal audio players to communicate with one another. By sending data through the wireless spectrum instead of over the airwaves, there is no need for the internal microphone to pick up and amplify sound. The result is clearer, more natural sound. When paired with hearing devices, Bluetooth allows the user to stream signals from your electronics directly to the hearing instruments. Hearing aids can connect with many different devices including television sets, cellphones, GPS systems and even other medical devices. Designed to be smaller and built to be smarter, Made-for-iPhone devices stream music, phone calls and other sounds directly from your iPhone®, iPad® or iPod Touch®. These technology-rich hearing aids have many great features, including upgraded sound quality, enhanced speech-processing technology and more.

Most hearing aid batteries are tiny and unable to supply enough power for a steady Bluetooth connection. To get around this, assistive listening devices called streamers have been developed. Usually worn around the neck, streamers provide a communication link between devices, picking up Bluetooth signals and transmitting them to and from hearing aids via an FM signal or electromagnetic field. In essence, the streamer works as a personal remote control for your hearing aids, enabling you to change the hearing program, raise or lower the volume and mute the streaming sound – all with the push of a button.

Rechargeable Technology


Now, our patients can hear without the hassle. Most manufacturers now offer rechargeable technology. With one overnight charge, you can enjoy an entire day of hearing, providing you with performance on the go. Many of these rechargeable devices also use traditional batteries, so you can have the freedom of rechargeable technology and the security of battery back-up.
