WebIt is also used in various kinds of audiometry, including pure tone audiometry, and the standard hearing test to test each ear unilaterally and to test speech recognition in the presence of partially masking noise. Auditory masking is exploited to perform data compression for sound signals ( MP3 ). See also [ edit] Cocktail party effect WebAbstract We measured masked thresholds for pulsed pure tone (5, 1.0, 2.0, and 4.0 kHz) in the presence of different levels of broad-band noise (nominally 0, 20, 40, and 60 dB/Hz). Several of the 16 cochlear-impaired listeners displayed masked thresholds that were considerably higher than those obtained from 10 normal listeners.
