[350m heliox saturated diving test--dynamic observation on hearing threshold, brainstem evoked response and acoustic impedance].

Zhonghua er bi yan hou ke za zhi, 1991
Four divers were investigated simulating a diving of 350m with saturated heliox under compression, performed in Jan 1989 at Navy Medical Institute. Changes in hearing threshold, brainstem evoked response and acoustic impedance were observed. The 4 divers experienced no tinnitus, hard of hearing and earache during compression and decompression ...
