Abstract

This report presents the results of an experimental investigation of the effects of using different source measurement techniques in implementing the coherence function for source identification purposes. Frequency domain measurements leading to the coherence function are developed with regard to providing a causal relation for a single input, single output, linear system. The use of a near microphone or accelerometer for source measurements is presented with particular interest paid to the effect of introducing noise into the input measurement. Experimental results show that while a near microphone provides a more accurate coherence statement than an accelerometer, the input of correlated noise may be a problem. The possibility of an empirical criteria for the source to noise signal difference at the near microphone is raised as a means to help avoid this problem.
