Book Description
This report describes an experiment to measure with an acoustic diffraction grating the fluctuations of a sound wave due to atmospheric turbulence. The grating corresponds to a bandpass filter with a bandwidth of 10-(2) cm-(1) in wave number. The measurement is related to the scattering of electromagnetic energy by periodic sound waves, an effect upon which the EMAC probe depends. Measurements were made at an acoustic wave length of 3.48 cm. Under the conditions of the tests, turbulence was found to have no effect on the sound wave. (Author).

Book Description
This book will discuss the propagation of sound in newly discovered or created materials, and in common materials which are being investigated with a fresh outlook. This four-volume set is intended for university industrial and government libraries serving engineering and research personnel working in acoustics. (Midwest).
