Abstract

The long-term Signal-to-Noise Ratio (SNR) at the input and output of compression amplification hearing aids (HA) are measured and computed. Systematic changes of long-term SNR from input to output are found. These changes are affected by both compression system parameters and signal properties of speech and noise. Such SNR changes may potentially affect perceptual performance for users of compression HAs. This is also investigated, although the current standing of this work does not provide a clear conclusion.
