Abstract
Temporal acuity, defined as the minimum detectable gap in an otherwise continuous noise, was measured with an adaptive version of the two-alternative forced-choice task. For 6 normal listeners, the minimum duration detectable decreased from an average of 20.3 ms at a noise level of 30 dB SPL to 3.2 ms at 80 dB SPL. By comparison, the temporal acuity of 4 listeners with conductive hearing losses, 2 with otosclerosis, and 7 with sensorineural hearing losses, was poorer than that for normal listeners at equal sound pressure levels. At higher sound pressure levels, the acuity of those with conductive hearing losses or otosclerosis approached normal values, but the acuity for listeners with sensorineural hearing losses did not. Nous avons mesuré l'acuité temporelle, définie comme la durée minimale d'une interruption d'un bruit par ailleurs continu pour qu'elle soit décelable, en appliquant une version particulière de la méthode des choix forcés entre deux alternatives. Chez 6 sujets jouissant d'une audition normale, ce temps passait en moyenne de 20,3 ms pour un bruit de 30 dB SPL à 3,2 ms pour un bruit de 80 dB SPL. Dans 4 cas de surdité de transmission, 2 cas d'otospongiose et 7 cas d'atteinte de l'oreille interne, nous avons trouvé une acuité temporelle moins bonne aux měmes intensités de bruit. Dans les cas de surdité de transmission et d'otospongiose, les valeurs se rapprochaient de la normale à des intensités de son plus élevées, mais il n'en était pas de měme pour les malades souffrant d'atteintes de l'oreille interne.Keywords
