Abstract


Wave field analysis of stationary sound fields can be performed with high spatial resolution when sequential measurements on a circle are employed. Applying a circular harmonics decomposition to wideband audio data requires a careful setup of the measurement process to avoid noise amplification at certain frequencies. To this end, measurements with several microphones at multiple radii are considered here. Three mathematically well-founded strategies to combine their measurement signals are compared regarding the resulting noise amplification. ©2009 IEEE.
