If you use hearing aids, you might be wondering about their effect on cellphone use. Some people who use hearing devices sometimes experience high-pitched whistling sounds or static due to radio frequency interference. To avoid this issue, consult the guide below.

Why the Interference?

Cellphone interference doesn’t occur for everyone who uses hearing aids, but when it does, it can be bothersome. Hearing aids are made up of three parts: a microphone, an amplifier, and a speaker. The microphone receives the sound and then converts the sound waves to electrical signals, which are then sent to the amplifier. The amplifier increases the volume of the signals and sends them out through the speaker and into your ear. Issues with digital cellphones occur when there’s an interference in radio frequencies, causing the electrical signals to produce buzzing, inaudible speech, and faulty connections.

What Is Hearing Aid Compatibility?

Hearing Aid Compatibility (HAC) allows wearers to determine which cellphones would be most compatible with their devices. The Federal Communications Commission (FCC) is now requiring cellphone manufacturers to test and rate their cellphones' HAC. The rating will allow you to determine how much interference you might experience while using your cellphone with your hearing aid. The testing is intended to decrease the amount of static and interference.

Cellphones that work well with hearing aids will have a microphone (M) rating of at least M3. The higher the M rating, the less interference and static you’ll experience. If your device uses one, you might also find a telecoil (T) rating. A T3 rating or higher will guarantee clarity.

How to Ensure Compatibility

While the HAC will help you choose a cellphone, hearing aids are also rated by the same measurements. You can determine the best compatibility by combining both ratings:

• A combined rating of 6: “Excellent”—highly usable
• A combined rating of 5: “Normal”—acceptable for regular use
• A combined rating of 4:  “Usable”—good for brief calls, but not suitable for regular use
