Frequency lowering is a well-known technology in hearing aids that shifts high-frequency sound to lower spectral regions. Research and clinical findings have revealed the challenges of developing a strategy that can provide access to high-frequency speech without introducing unacceptable amounts of low-frequency distortion. Oticon Speech Rescue, the latest frequency lowering processor on the ma...
