Abstract:Purpose: Develop a test to evaluate frequency compression by identifying and applying fricative phonemes. Methods: A speech material was composed of 24 monosyllabic words, containing the phonemes /s, z, f, v, ∫, /. Eight subjects recorded words, for a total sample of 192 recordings. Low-pass filters were applied to words with cutoff points values of 1,5 kHz; 2 kHz e 3 kHz, in order to prevent sound detection in the filtered frequency bands, simulating hearing loss at high frequencies. The test was applied to … Show more
