Flat-gain amplification fails for frequency-dependent hearing losses
Evidence
In short, a level corresponding to 60 dB SPL(C) free-field was selected as the presentation level to be used with NH test subjects. For the HI test subjects, it was then ensured that in each one-third octave band the RMS level of the stimulus was at least 15 dB above hearing threshold before pinna-cue shaping. The required gain was added by designing an IIR filter in the test software to shape the stimulus. — Dijk, Pim van, Physiology, Psychoacoustics and…, 3052 (
