I use a Ameriphone XL 40 telephone. This phone has strong variable amplification. It also has adjustable tones.
The problem is and please correct me if I am wrong- my hearing aid already has been adjusted for for my sensori-neural loss. If I use the XL 40 i have no way to neutralize its adjustable frequency tones. I do not need dual frequency tone adjustments- just dual loudness (my hearing aid and the phone.).
It is my thinking- dual tone increases distortion.
What are your thoughts/experiences?
thanks in advance
