Answer:

because Sounds in the ocean – according to fishes

Acoustic waves have to faces. Sound is both a pressure disturbance and a motion of particles, generated by a sound source (basically a structure moving back and forth). These two features of sound, pressure and motion, goes hand in hand: it is the MOVEMENT of particles towards and away from each other that GENERATE the increased and decreased pressure. When we talk about HUMAN hearing, we usually think of the pressure component. It is the sound pressure fluctuations that put the tympanic membrane into motion, DRIVING our middle-ear ossicles and eventually pumping the fluid in the cochlea, where the hair CELLS are located that detect sound. Like all other mammals, we are thus primarily sensitive to the pressure component of the sound field.
