How does acoustic beamforming arrays work
WebAcoustic Beamforming Using a Microphone Array Copy Command This example illustrates microphone array beamforming to extract desired speech signals in an interference-dominant, noisy environment. Such operations are useful to enhance speech signal quality for perception or further processing. WebBeamforming for Small-Spacing Acoustic Vector Sensor Array Using Optimal Beampattern Synthesis Technique. Abstract: Traditional low-frequency acoustic senor arrays will always be very large and not easy to be implemented. So it is meaningful to study small-spacing underwater acoustic sensor arrays.
