However, the design and implementation of microphone arrays with beamforming algorithms is not a trivial task when it comes to processing broadband signals such as speech. Indeed, in most sensor arrangements, the beamformer tends to have a frequency-dependent response. One exception, perhaps, is the family of differential microphone arrays (DMAs) that have the promise to form frequency-independent responses. Moreover, they have the potential to attain high directional gains with small and compact apertures. As a result, this type of microphone arrays has drawn much research and development attention recently. This book is intended to provide a systematic study of DMAs from a signal processing perspective. The primary objective is to develop a rigorous but yet simple theory for the design, implementation, and performance analysis of DMAs.Springer Topics in Signal Processing,1866-2609 ;6MicrophoneMicrophone.621.3822Benesty Jacob721063Chen J(Jingdong)1764058MiAaPQMiAaPQMiAaPQBOOK9910437885003321Study and design of differential microphone arrays4204796UNINA
