Zm. Wang et Wt. Chu, ENSEMBLE AVERAGE REQUIREMENT FOR ACOUSTICAL MEASUREMENTS IN NOISY ENVIRONMENT USING THE M-SEQUENCE CORRELATION TECHNIQUE, The Journal of the Acoustical Society of America, 94(3), 1993, pp. 1409-1414
This paper describes an experiment that provides additional evidence t
o demonstrate the possibility of making acoustical measurements in noi
sy environments by using an m-sequence correlation technique. A criter
ion for choosing the proper number of synchronous averages is establis
hed and a demonstration of making noise reduction measurement between
two rooms is also given.
