Auditory Analysis of Vowel-Like Sounds
The results of traditional masking experiments do not fit in with the effect of “two-tone inhibition” revealed by single-nerve-fibre studies. This is considered a serious objection against the interpretation of a masking pattern as reflecting the auditory spectrum of a masker. The results of a different masking paradigm, based on the pulsation threshold, do reveal an effect similar to “two-tone inhibition”. Therefore, such pulsation-threshold patterns might reflect more accurately the auditory spectrum of the masker. Pulsation-threshold patterns of three vowel-like sounds were determined. These were compared with the spectral patterns of the “vowels” after analysis with a 1/3 octave-band filter with running center frequency. It appeared that the pulsation- threshold patterns are sharper than the 1/3 octave-band spectra and, in some cases, even more pronounced than the original vowel spectra. This has interesting implications with regard to vowel-perception theories, such as theories on “formant extraction”.
