Acoustic signals in Tupaia glis and their classification

Physical characteristics of acoustic signals and peculiarities of their rec ognition and classification in Tupaia glis are considered. The leading char acter in recognizing various acoustic signals is the frequency filling of s ounds. A shape of the dynamic spectrum is an accompanying characteristic. T he temporal sound parameters and the pattern of distributing energy between spectral maximums are used in classification of signals within the motivat ion and topological range in Tupaia. The perception of acoustic signals in Tupaia is of discrete character.
