Abstract
Many source locating schemes require a considerable investment of hardware and software. The method due to Fisher et al. [M.J. Fisher, M. Harper‐Bourne, and S. A. L. Glegg, J. Sound Vib. 51, 1 (1977)] appears to be the most readily implemented. The present procedure is an “economy” version of the former approach: time delays between signal reception by several observers are used in a generalized triangulation algorithm to yield estimates of virtual source positions of jet noise. The delays are measured by means of cross correlations of narrowband near‐ and farfield microphone signals. Source distributions computed therefrom are compatible with those derived from more elaborate source locating techniques. The method is well suited for a “quick‐look” analysis [Work supported by NSERC, Canada.]
