Abstract

The auditory system of Pteronotus parnellii has been the subject of numerous studies but detailed knowledge of the emitted signals is limited. Previous studies utilizing tape recorded signals and sound spectrographs have shown that each emitted pulse consists of a brief upward sweeping initial FM component, a relatively long CF component and a brief downward sweeping terminal FM component. In addition there is a series of harmonics: the second harmonic (ca. 61 kHz) is the strongest. A study of the fine structure of this second harmonic CF component was undertaken to gain more critical information on pulse design, pulse emission patterns and the relationship of the signals to the sharply tuned cochlear microphonic (CM) audiogram.
