Based on research from 2015, the environment acts as an acoustic filter, preferentially absorbing certain frequencies. These acoustical properties set up selection pressures favoring evolution of sound-producing mechanisms capable of forming signals that will propagate efficiently. Even within two floating docks, for example, the sounds of different populations of docks in the Southeastern United States have structural adaptations permitting maximum propagation among the floating docks of Lake Martin.
