Opis

This book offers a uniquely complete and rigorous study of sound propagation and scattering in moving media that have deterministic and random inhomogeneities in adiabatic sound speed, density, and medium velocity. It is a resource for engineers and scientists who work in atmospheric and oceanic acoustics, aeroacoustics, outdoor noise control, a
