Ensemble average requirement for acoustical measurements in noisy environment using the m-sequence correlation technique
Wang Zuomin, W. T. Chu · The Journal of the Acoustical Society of America · 1993
This paper describes an experiment that provides additional evidence to demonstrate the possibility of making acoustical measurements in noisy environments by using an m-sequence correlation technique. A criterion for choosing the proper number of synchronous averages is established and a demonstration of making noise reduction measurement between two rooms is also given.
