Spatiotemporal Gradient Analysis of Differential Microphone Arrays
Analyzing the sound pressure field as a multivariate function of spatial location and time illustrates the working principles of gradient and differential microphone arrays. This analysis provides the means for the adjustment of various array parameters, such as array orientation and shape, inter-microphone distances, and microphone signal delays. By using this new perspective, designers have a clear interpretation of gradient and differential microphones and microphone arrays.
