Medium-specific sound transmission across solids, liquids, and gas yields distinct sonic ecologies.

Evidence

Sound is transmitted in air and in water as well, but soil and rock are permeable to vibration to some extent. Thus, the transmission of sounds that occurs in solids, in liquids, and in a gas medium has different and distinct physical modalities (such as speed, impedance, excess of attenuation). For this reason, we can expect different mechanisms of perception and strategies of communication used by organisms living in these different contexts, that is, we expect different “sonic ecologies.” — Almo Farina, Soundscape Ecology, 52
