WebJan 10, 2011 · It is often enough to localize environmental sources of noise from different directions in a plane. This can be accomplished with a circular microphone array, which can be designed to have practically the same resolution over 360°. The microphones can be suspended in free space or they can be mounted on a solid cylinder. This … 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.

WebSep 7, 2007 · A new DOA estimation method using a circular microphone array Abstract: This paper proposes a new DOA (direction of arrival) estimation method based on circular microphone array. For an arbitrary number of microphones, it is analytically shown that DOA estimation reduces to an efficient non-linear optimization problem. WebThis paper proposes a real-time method for capturing and reproducing spatial audio based on a circular microphone array. Following a different approach than other recently proposed array-based methods for spatial audio, the proposed method estimates the directions of arrival of the active sound sources on a per time-frame basis and performs …
