Forest edges are sonic discontinuities segregating wind noise from animal sounds.

Evidence

Wind-generated noise and animal-borne sounds are differently distributed when core and edge areas are compared. In particular, forest edges represent not only an ecological discontinuity and a tension zone but is also a cause of sonic discontinuity. — Almo Farina, Soundscape Ecology, 357
