Habitat-specific ambient noise can drive the evolution of animal signals

Evidence

The distribution of noise in specific frequencies probably affects the acoustic selection of species, because animal signals have a great plasticity and can be modified in a very short time according to environmental conditions. In conclusion, it is reasonable to hypothesize that ambient noise may drive signal evolution. In fact, ambient noise can mask the singing activity of males, concurring to reduce the margin of affordability of female recognition of honest signals. — Almo Farina, Soundscape Ecology, 336
