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).
