How Does SoundRecover2 Frequency Lowering Technology Work?

Question

Can you briefly describe how Phonak's new SoundRecover2 frequency lowering technology works?

Answer

SoundRecover2 allows a greater compressed region to extend to those with more profound hearing loss, and also to those with left corner and ski-slope audiograms.  Inputs above the upper cut-off frequency are always compressed with a fixed compression ratio.

In the mid-frequency area between the upper and lower cut-off frequencies, the processing depends adaptively on the input signal. In this mid-frequency area, the system determines adaptively whether frequency compression will be active or not.

In the case of more low frequency content in the input signal, frequency compression takes place with the upper cut-off frequency to “protect” the low-frequency sounds from being compressed.

In case of more high frequency content, frequency compression takes place with the lower cut-off frequency to restore audibility of the high-frequency sounds.

SoundRecover2 restores access to high-frequency sounds (left side) and at the same time protects low- and mid-frequency sounds.
