Digital Frequency Compression Reduces Feedback

First, this problem is very common. Although, research from the last decade clearly indicates that attempting to amplify severe to profound high frequency losses is useless (loss greater than 65dB at 2KHz and above), most products on the market still amplify high frequencies. This introduces distortion, discomfort and feedback and does not improve audibility of voiceless sounds.

With Digital Frequency Compression (DFC), the original high frequency voiceless sounds are compressed into lower frequencies where you have better residual hearing and need less amplification. This allows us to decrease gain in the high frequencies where your hearing is more damaged. The decrease in gain will also reduce feedback, distortion, and discomfort. A side benefit of DFC is it reduces feedback because the output signal is never at the same frequency as the input signal.
