Species in a habitat partition acoustic space into distinct non-overlapping bandwidths.

Evidence

The acoustic niche (hypothesis) is based on the ecological niche concept (Hutchinson, 1957; Hutchinson, 1978) and on the empirical observations in which only a few parts of species-specific sounds overlap each other, avoiding cacophonic effects (Krause, 1987; Krause, 1993). The acoustic niche hypothesis represents an important model used to understand better how species enter into competition or avoid competition during their acoustic performances. … In this way, species occupy a temporal and frequency bandwidth that results in the Krause concept of “the animal orchestra” (Krause, 2012). The premise being that the voice of each organism in a given habitat strives for its own bandwidth – a clear channel of transmission and reception – to avoid masking, much like instruments in an orchestra are organized. — Bernie Krause and Almo Farina, Using Ecoacoustic Methods to Survey the…, 39
