Abstract
Analytical results have been obtained for the cross-spectral density of the noise pressure on an infinite plane baffle located beneath a fluid layer, when random pressure fluctuations present on the upper surface of the layer have spatial scales that are small in comparison with an acoustic wavelength, and the baffle acts as a “locally reacting” surface. (1) If the layer thickness is small in comparison with an acoustic wavelength, and large in comparison with the length scales of the surface pressure, the pressure spectral density on the baffle is inversely proportional to the layer thickness. The random pressure on the baffle is isotropic, with correlation lengths proportional to the layer thickness. (2) If the layer thickness is large in comparison with an acoustic wavelength, the pressure spectral density on the baffle is independent of the layer thickness. The random pressure on the baffle is isotropic, with correlation lengths proportional to the acoustic wavelength. [Work supported by the Office of Naval Research, Code 468.]
