hearing devices. Not all phones have been rated. Phones 
that are rated have the rating on their box or a label 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.

 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.

 Phones rated T3 or T4 meet FCC requirements 

and are likely to be more usable with a hearing device’s 
telecoil (“T Switch” or “Telephone Switch”) than unrated 
phones. T4 is the better/higher of the two ratings. (Note 
that not all hearing devices have telecoils in them.)

Hearing devices may also be measured for immunity to 
this type of interference. Your hearing device 
manufacturer or hearing health professional may help 
you find results for your hearing device. The more 
immune your hearing aid is, the less likely you are to 
experience interference noise from mobile phones.

If you use any other personal medical devices, consult the 
manufacturer of your device to determine if it is 
adequately shielded from external RF energy. Your 
physician may be able to assist you in obtaining this
