Safety

 

 

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.

 

 

T-Ratings: Phones rated T3 or

 

 

T4 meet FCC requirements and

 

 

are likely to generate less

 

 

interference to hearing devices

 

 

than phones that are not

 

 

labeled. T4 is the better/higher

Safety

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 above example, 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 is synonymous for T ratings. This should provide the hearing aid user with “normal usage” while using their hearing aid with the particular wireless phone.
