[The influence of experimental vestibular stimulation on directional hearing (author's transl)].

Interaural differences of time and intensity do not explain the good directional hearing capacity of persons with one deaf ear or asymmetric hearing loss. These persons estimate the direction of sounds by head movements. The alteration of sounds depends on the amplitude of the head movement, on the degree of turning the head and on a normal vestibular system. The influence of vestibular stimulation on directional hearing and the resulting virtual alterations on the direction of sound could be demonstrated.
