Abstract:
This work examined the effect of band power weighting on understanding stimuli synthesized with temporal envelope or Hilbert-fine-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 power-weighting conditions, suggesting that band power weighting did not notably influence the intelligibility of stimuli synthesized with temporal information from a few bands.

Band Formation:
When atoms are brought close together, as in a solid, these discrete energy levels begin to split due to the overlap of electron orbitals from adjacent atoms. This split occurs because of the Pauli exclusion principle, which states...
