Abstract : Five monaural chinchillas were exposed to impulses of 168 dB SPL, and the loss of sensitivity for the pure tones of .3, .75, 1.5, 4.0, 6.0, 7.9, 11.0, 14.5, and 16.5 kHz was determined through an avoidance conditioning technique. The recovery of sensitivity was studied over 64 days after exposure. The chinchillas proved to be much more susceptible to this noise than the rhesus monkey. (Author)
