听觉阈值的测定是通过对10条鳕鱼（Gadus morhua）的频率为17.6、35.3、70.7、141、283和400周/秒的声音刺激的条件反应来进行的。条件反应是心律的改变。它是通过电击作为无条件刺激建立的，可以在示波器上监测。阈值表明鳕鱼对声音的敏感性高达283周/秒。在400周/秒的速度下，他们相对失聪。实验水槽中的背景噪声高到足以影响阈值;因此无法确定绝对阈值。
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 stimulus, and could be monitored on an oscilloscope.The thresholds indicated cod to have high sensitivity to sounds up to 283 cycles/sec. At 400 cycles/sec they were relatively deaf. Background noise in the experimental tank was high enough to influence thresholds; an absolute threshold could therefore not be determined.
