THE ROLE OF THE PINNA IN SPEECH INTELLIGIBILITY.

Abstract

Nine normal-hearing subjects listening through earphones were required to identify spoken words in a noisy background. Acoustic stimulation was picked up alternately by bare microphones and by microphones equipped with casts of human external ears (pinnae). Test scores and subjective impressions both indicated a highly significant and consistent superiority for the pinna condition. Sound level measurements and sonograms confirmed the superiority of the pinna condition. (Author)
