An Audiogram of the Atlantic Cod, Gadus morhua L.
Auditory thresholds were determined by means of a conditioned response to sound stimuli at frequencies 17.6, 35.3, 70.7, 141, 283, and 400 cycles/sec for 10 cod, Gadus morhua. The conditioned response was a change of cardiac rhythm. It was established through an electric shock as unconditioned stimu...
