  • Title: [Some problems in measuring the frequency-resolving power of hearing].
    Author: Supin AIa.
    Journal: Ross Fiziol Zh Im I M Sechenova; 2004 Aug; 90(8):1001-14. PubMed ID: 15552366.
    Abstract:
    In spite of detailed elaboration of masking methods of measuring the frequency selectivity of hearing, such measurements actually are not in use for diagnostics purpose because of their time-consumption and ambiguity of extrapolation of the results to perception of complex sound spectrum patterns. A method of direct measuring of spectrum resolving power using rippled-noise test, is suggested. Results of measurements have shown that the actual ability of hearing to discriminate complex sound spectra is higher than that predicted by acuteness of auditory frequency filters: dependence of acuteness of auditory frequency filters on sound level does not influence the ability to discriminate complex spectra; and the influence on interfering noise on the frequency resolving power can not be explained by a decrease of the spectral contrast by the spread of excitation.
