For the average hearing aid wearer, the ability to use telephone effectively is a very important consideration. One of the needs as a human is to be able to communicate with the world and our loved ones. In the modern world that incudes the ability to speak on the phone and video calls.
One of the most common issues plaguing the hearing aid wearer is the feedback or whistling that can occur when the wearer attempts to use the telephone in a normal manner. Although some devices, like in the ear hearing aids, will work just fine by placing the handset near the ear, but not directly covering it. A slight tilt of the handset one way or the other may be all you need to stop the whistling. With behind the ear hearing aids it is beneficial to place the speaker of the phone at the top of the ear where the microphone of the hearing aid is positioned. The sound from the phone can then be picked up and amplified according to the settings of the hearing aid.
