  • Title: [Registration of various classes of otoacoustic emission in definition of acoustic sensitivity in different forms of neurosensory hypoacusis].
    Author: Fridman VL.
    Journal: Vestn Otorinolaringol; 2003; (6):20-3. PubMed ID: 14671573.
    Abstract:
    To establish correlations between parameters of otoacoustic emission and audiometric thresholds, we have examined 30 ears (28 patients) with high-frequency neurosensory hypoacusis. The analysis of the findings was made in microstructural frequency resolution. It was discovered that peaks of spontaneous otoacoustic emission correspond by frequency range to minimal thresholds of audibility in all the cases. Minimal values of audibility thresholds correlate also by frequency with maximal values of amplitudes of the response signal of delayed evoked otoacoustic emission with good sigmal/noise in all the examinees as well. 23 ears demonstrated 'mirrow' correlation of pure-tone audiogram with DP-gram - a rise in behavioral thresholds corresponds to amplitude-lowering response signals in frequency range 3-6 kHz.
