At the Fifty-fifth Meeting of the Acoustical Society of America [.J. Acoust. Soc. Am. 30, 670 (1958)], some results from field measurements on the scattering of sound were presented. In the present paper, results from laboratory experiments are reported. Pulses of 100 kc/sec sound, transmitted through a region of turbulence, are analyzed by means of a pulse height analyzer and counter. The pulse height distribution is determined for various scattering angles and the corresponding scattered sound energy is evaluated. In addition to these results on scattering of a collimated beam of sound, some preliminary results on the scattering of a cylindrical wave are presented. [This work was supported in part by the U. S.
