WebThe problem of direction of arrival (DOA) estimation with a circular microphone array has been addressed with classical source localization methods, such as the model-based methods and the param etric methods. These methods have an advantage in estimating the DOAs in a blind manner, i.e. with no (or limited) prior knowledge about the sound sources. WebIn this array, the sound from the sides is attenuated by 6 dB, whereas it was only attenuated by 3 dB in the 2-microphone broadside array. However, aliasing (cloverleaf pattern) occurs at even lower frequencies now because the total distance between all elements has been increased from 75 mm to 150 mm.
