[The effect of noise trauma on speech discrimination in silence and under influence of party noise (author's transl)]. 1978

H P Weibel, and J Kiessling

Speech audiometry investigations were carried out in silence and under action of cocktail party noise in 44 soldiers. The testing subjects were grouped according to age and degree of noise lesion. The statistical evaluation of discrimination losses measured in silence and under acting party noise indicated that noise lesions induced considerable discrimination losses even in young subjects particularly under cocktail party noise conditions. Discrimination decreases significantly as the degree of noise trauma increases. In order to assess the real effect of the hearing loss caused by noise trauma upon speech discrimination, the tests of speech audiometry should be performed under noise conditions.
