62 Safety persons with hearing disabilities. While some wireless phones are used near some hearing devices (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 noise, and phones also vary in the amount of interference they generate. The wireless telephone industry has developed a rating system for wireless phones, to assist hearing device users to find phones that may be compatible with their hearing devices. Not all phones have been rated. Phones that are rated have the rating on their box or a label located on the box. 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 phone successfully. Trying out the phone with your hearing device is the best way to evaluate it for your personal needs. M-Ratings: Phones rated M3 or M4 meet FCC requirements and are likely to generate less interference to hearing devices than phones that are not labeled. M4 is the better/higher of the two ratings. Hearing devices may also be rated. Your hearing device manufacturer or hearing health professional may help you find this rating. Higher ratings mean that the hearing device is relatively immune to interference noise. The hearing aid and wireless phone rating values are then added together. A sum of 5 is considered acceptable for normal use. A sum of 6 is considered for best use. In the example to the left, if a hearing aid meets the M2 level rating and the wireless phone meets the M3 level rating, the sum of the two values equal M5. This should provide the hearing aid user with "normal usage" while using their hearing aid with the particular wireless phone. "Normal usage" in this context is defined as a signal quality that's acceptable for normal operation. The M mark is intended to be synonymous with the U mark. The T mark

While some wireless phones are used near some hearing devices (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 noise, and phones also vary in the amount of interference they
generate.
The wireless telephone industry has developed a rating system for
wireless phones, to assist hearing device users to find phones that may
be compatible with their hearing devices. Not all phones have been rated.
Phones that are rated have the rating on their box or a label located on the
box.
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 phone
successfully. Trying out the phone with your hearing device is the best way
to evaluate it for your personal needs.
M-Ratings: Phones rated M3 or M4 meet FCC requirements and are likely
to generate less interference to hearing devices than phones that are not
labeled. M4 is the better/higher of the two ratings.
Hearing devices may also be rated. Your hearing device manufacturer or
hearing health professional may help you find this rating. Higher ratings
mean that the hearing device is relatively immune to interference noise. The
hearing aid and wireless phone rating values are then added together. A
sum of 5 is considered acceptable for normal use. A sum of 6 is considered
for best use.
In the example to the left, if a hearing aid meets the M2 level
rating and the wireless phone meets the M3 level rating, the
sum of the two values equal M5. This should provide the
hearing aid user with “normal usage” while using their
hearing aid with the particular wireless phone. “Normal usage” in this
context is defined as a signal quality that’s acceptable for normal
operation.
