Abstract

This work examined the effect of band power weighting on understanding stimuli synthesized with temporal envelope or Hilbertfine-structure (HFS) waveforms. The power of modulated carrier in a vocoder model or HFS waveform was level-matched to that of the bandpass filtered signal (matched condition) or equalized across bands (flat condition). The processed stimuli were played to normal-hearing
listeners to recognize. For both vocoded and HFS stimuli, there was no significant performance difference between the matched and flat powerweighting conditions, suggesting that band power weighting did not notably influence the intelligibility of stimuli synthesized with temporal information from a few bands.
