[Nose and speech discrimination with specific hearing aid systems (author's transl)].

This study compares speech discrimination and the use of hearing aids of the PC (peac-clipping) system and the AGC (compression) system. After random selection 34 subjects were used and grouped according to the unit system they had been supplied with. Both groups were tested under the same conditions. During noise exposure the group supplied with the AGC aids achieved better results significantly at a 5% level. The results indicate that the assumption that PC hearing aids operate better in noise than AGC aids cannot be substantiated.
