Measured and Theoretical Performance Comparison of a Broadband Circular Microphone Array

We present a comparison of the measured and theoretical performance of a 24 microphone baffled circular microphone array. The signal-to-noise ratio of the circular microphone array is obtained by analysing the spatial aliasing error, the microphone placement error, and the white noise gain. The circular microphone array has a frequency range of operation from 50 Hz to 16 kHz, and we show that the order of the beamformer should be changed across frequency, so that the signal-to-noise ratio for the beamformed signal is above a specified threshold value for the entire frequency range of operation.
