Research is ongoing with respect to how, and how well, marine crustaceans cam hear. Since they live in a liquid medium the importance of sound and the strategy for detecting it are different from vertebrates. If you consider sound to be a type of motion in air waves (a compression and rarefaction) and wind to be a continuous motion of air, the lobster would seem to at least have one sense dedicated to both effects. Lobsters, crabs and shrimp have an array of sensory hairs on their bodies which detect movement in water including the vibration in water we would perceive as sound. They also have internal sac-like sensory organs called statocysts, associated with detection of orientation, which are believed to be stimulated by sound. Marine invertebrates also have sensors in their flexible appendages like legs and antennae that can detect seismic vibrations.

Lobsters have been shown to at least be sensitive to low-frequency underwater sounds in the range of 20 to 300 Hz. By comparison, good human hearing might go from around 20 up to about 20,000 Hz.
