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 |
102 | 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. “Normal usage” in this context is defined as a signal quality that is acceptable for normal operation.
