From an acoustic point of view, the fact that the equations are the same should not mask the major differences between water and air. Water has a density around a thousand times greater than air, and a compressibility twenty times lower. In fact, the fluctuation in acoustic density ρ is linked to acoustic pressure p by the relationship :
where c is the celerity of sound.
In air, the reference pressure...
