There is still some misunderstanding in the industry about what makes a hearing aid wireless. Over the next week, I will be posting the 5 most common myths associated with wireless hearing technology.
Myth #1: “My hearing aids already are wireless – they use Bluetooth.”
Despite how manufacturers may be positioning these products, most “wireless” hearing aids on the market today don’t actually have true wireless capabilities. Some so-called “wireless” hearing aids actually rely on an older technology called near field magnetic induction. These hearing aids use a Telecoil to receive a signal sent from an intermediary device (a neck loop transmitter), which is worn around the user’s neck. The limitations of this technology are that the transmitter must be within 3 feet of the hearing instrument. These hearing instruments do not contain wireless technology. The Bluetooth connection really only exists between the neck loop and the audio device (for example a television or other audio device) which translates the Bluetooth signal into a near field magnetic induction signal.
