Sound Spectrographic Analysis: Suggestions for Facilitating Auditory Imagery

Abstract

During the last thirty years the rapid advances in the study of acoustic communication in animals have been largely due to the use of the sound spectrograph for analysis. It has the capacity for simultaneously analyzing three parameters of sound: frequency, time and relative loudness; because the frequency analysis is spectral, tonal quality or timbre can also be deduced. These visual displays of sound patterns have enabled students of bioacoustics to communicate their results in a
