Abstract
During a slight temporary salicylate-induced hearing loss, the normal loudness difference between broad-band noise and narrow-band noise was markedly reduced at all levels, except the highest. The critical band, measured at 1 kHz by means of a loudness summation method, appeared to become wider in 9 out of 16 subjects, to a degree roughly proportional to the degree of hearing loss. However, some discrepancies in the data and a rather large intersubject variability of the loudness estimates were present. The localization of the mechanism which forms the basis for the critical band concept is discussed in view of the results. Au cours d'une surdité légère et passagère due au salicylate, la différence, normale, de sonie entre une bande large de bruit et une bande étroite de bruit s'est trouvée réduite sensiblement pour tous les niveaux d'intensité sauf les plus forts. La bande critique pour 1 kHz mesurée par la méthode de l'intégration des sonies est apparue plus large chez 9 sujets sur 16, et cela d'une façon approximativement proportionnelle au degré de surdité. Nous devons cependant retenir un manque d'uniformité dans les résultats et une variabilité assez importante de sujet à sujet a propos de l'estimation de la sonie. A la lumière des résultats obtenus, nous discutons la localisation du mécanisme sur lequel est basé le concept de bande critique.Keywords
