Influence of Components Precision on Characteristics of Dual Microphone Arrays

Microphone arrays have great potential in practical applications due to their ability for significant improvement in speech quality and signal to noise ratio in noisy environments. Large amount of scientific papers and patents have been devoted to different algorithmic techniques for producing optimal output of microphone array using different optimization criteria. However, in practice performance of microphone arrays in a large extent depend on the quality of their components such as amplitude matching, phase matching, error in distance between microphones and etc. This paper analyses dependence of a dual microphone array characteristics on the above factors.
