DEVELOPMENT OF NOISE MEASUREMENT TECHNIQUES AND PROCEDURES FOR USE IN FLUID PIPING SYSTEMS.

Abstract

The report presents the results of experimental and theoretical studies of four aspects of acoustic measurements in piping systems. The first deals with the effects of air in the system, the second deals with the use of transparent plastic test systems, and the third and fourth studies deal with the background levels associated with turbulent fluid flowing past a hydrophone and with the generation of acoustic signals by high velocity flows through devices which are meant to act as attenuators.
