A transient testing technique for the determination of matrix parameters of acoustic systems, II: Experimental procedures and results

Abstract This paper deals with the application of a transient testing technique for the determination of matrix parameters of acoustic systems. Experiments were conducted for six systems of various geometrical configurations such as (1) a section of pipe, (2) a small expansion chamber, (3) a large expansion chamber, (4) partition pipes, (5) partition chambers and (6) an expansion chamber with insertion pipes. Two series of results were obtained for these systems, one concerned with the evaluation of matrix parameters for blockable and reciprocal cases and the other for the non-blockable and reciprocal types. Excellent agreement between experimental and theoretical results is illustrated by some typical results obtained for systems (1) and (3).
