Discrimination vocale en présence de bruit dans les différents types de surdité

Abstract

Speech Discrimination in Presence of Noise in Different Kinds of Hearing Loss

When the threshold of hearing was poorer than 70 dB HL, the speech audiometric curve was always made worse by the presence of noise. By contrast, if the threshold was better than 70 dB HL, the speech audiometric curve was improved by noise in 35% of cases. This effect was particularly noticeable in the case of cupul-shaped or ‘plateau’-shaped speech curves

In conductive hearing losses, the effect of noise was always to produce a deterioration in the speech audiogram, This is in contrast to what one would expect in view of a paracousis willisii
