Each habitat has a distinctive ambient noise spectral profile
Evidence
Ambient noise is produced by a broad spectrum of different spectral frequencies. A large variety of frequencies is produced by wind passing through leaves (rustling) and twigs. Wind passing over substrates generally produces low-frequency sounds. Anthropogenic noises pertain to a wide spectrum of frequencies, but the anthrophonies that are real intruders at a growing rate in every environment are generally of low frequency. The spectral profile of every environment is peculiar for that ambient or, better, is habitat specific. It reflects geography, topography, botanical composition, and vegetational structure (clearings, core/edge areas, shape of patches, fragmentation level and typology, land use, level of human contamination, etc.). — Almo Farina, Soundscape Ecology, 1256
