Compatibility with Wireless Devices
When wireless devices are used near hearing devices (such as hearing aids and
cochlear implants), users may detect a buzzing, humming, or whining noise. Some
hearing devices are more immune than others to this interference, and wireless
devices also vary in the amount of interference they generate.
The wireless telephone industry has developed ratings to assist hearing device users
in finding wireless devices that may be compatible with their hearing devices. Not
all wireless devices have been rated. Wireless devices that are rated will have the
rating displayed on their box together with other relevant approval markings.
The ratings are not guarantees. Results will vary depending on the user's hearing
device and hearing loss. If your hearing device is vulnerable to interference, you may
not be able to use a rated wireless device successfully.
Consulting with your hearing health professional and testing the wireless device with
your hearing device is the best way to evaluate it for your personal needs.
How the ratings work
M-Ratings: Wireless devices rated M3 or M4 meet FCC requirements and are likely
to generate less interference to hearing devices than wireless devices that are not
labeled. M4 is the better/higher of the two ratings.
