High input levels can cause saturation and "fast pumping" effects in hearing aids. The resulting distortion products and changes in speech amplitude envelope are examined in the time domain. Spectrograms reveal changes in speech elements not apparent with time domain methods.
Key Words: compression hearing aids, compression, time domain, spectrograms, hearing aid processed speech, saturation, hearing aids, amplitude envelope, hearing aids
