M 3 + M 2 = 5

T 3 + T 2 = 5

 

 

In the above example, if a hearing

and the wireless phone meets

the M3 level rating, the sum of

e

the two values equal M5. This is

ty

synonymous for T ratings. 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 is

 

 

acceptable for normal operation.
