The auditory thresholds for 7 specimens of the sharp toothed eel Muraensox cinerus were measured at 5 frequencies by heartbeat conditioning method using pure tones coupled with a delayed electric shock.
The audible range of the sharp toothed eel extended from 80㎐ to 300㎐ with the best sensitivity around 80㎐ and 100㎐. In addition, the auditory thresholds over 200㎐ increased rapidly. The mean auditory thresholds of the sharp toothed eel at the test frequencies of 80㎐, 100㎐, 200㎐ and 300㎐ were 87㏈, 86㏈, 105㏈ and 126㏈, respectively.
Auditory masking was determined for the sharp toothed eel by using masking stimuli with the spectrum level range of about 70~80㏈ (0㏈ re 1μ㎩/√㎐). According to white noise level, the auditory thresholds increased as compared with thresholds in a quiet background noise. The noise spectrum level at the start of masking was distributed at the range of about 64㏈ within 80~100㎐. Critical ratio ranged from minimum 24㏈ to maximum 40㏈ at test frequencies of 80㎐~200㎐.
