Regulations for Wireless Devices

The U.S. Federal Com
requirements for digital wireless mobile devices to be compatible
with

hearing aids and other assistive hearing devices.

When individuals employing some assistive hearing devices (hearing
aids and cochlear implants) use wireless mobile devices, they may
detect a buzzing, humming, or whining noise. Some hearing
are

more immune than others to this interference noise, and mobile

devices also vary in the amount of interference they generate.
The wireless telephone industry has developed a rating system for

wireless mobile devices to assist hearing device users find mobile
devices that may be compatible with their hearing devices. Not all
mobile devices have been rated. Mobile devices that are rated have

The ratings are not guarantees. Results will vary depending on the

user's hearing device and hearing loss. If your hearing device
happens to be vulnerable to interference, you may not be able to
use a rated mobile device successfully. Trying out the mobile device

Hearing devices may also be rated. Your hearing aid manufacturer or
hearing health professional may help you find this rating. Higher
ratings mean that the hearing device is relatively immune to

interference noise.
Under the current industry standard, American National Standards

the sum of the two values equals M5.
Under the standard, this should provide the hearing aid user with

normal use while using the hearing aid with the particular

excellent performance.

However, these are not guarantees that all users will be satisfied.
T ratings work similarly.
