Masked auditory thresholds from the bat,Rhinolophus ferrumequinum

Summary

Thresholds for pure tones masked by broad band white noise were measured in the bat,Rhinolophus ferrumequinum, using a classically conditioned response to shock. The critical ratios obtained from the masked thresholds differ from those obtained from other mammals in that some of the fine structure of the behavioural hearing curve is reflected in the critical ratio curve. This difference is discussed in relation to specializations of the auditory system of this bat.
