[Acoustics Science is concerned with the control, effects, production, transmission, and reception of sound. It is the study of mechanical waves in solid, liquid or gas in different media. Acoustics include ultrasound, vibration, infrasound, speech, and sound. Acoustical engineering is concerned...
[Microphone array (MA) involves several microphones positioned at diverse spatial locations. According to the sound propagation fundamentals, the multiple inputs can be handled to attenuate or to enhance the stemming signals from specific directions (desired signal) in the presence of demeaning...
[Estimating the direction of non-stationary moving array as well as moving narrowband sources is considered an active research area. The most cutting-edge techniques are originated from the maximum likelihood (ML) and expectations maximization (EM) methods as they have a form of recursive...
[In an enclosed environment, multi-source DOAE is an inspiring due to environmental noise, room reverberation, and the source spectra overlapping. The DOAE of acoustic sources is imperative for several applications including beamforming, automatic camera steering, robotics and surveillance. The...
[DOAE is essential in several applications including automatic steering of video camera and multiparty teleconferencing for steering and beamforming in order to suppress reverberation and noise as well as to improve the speech intelligibility.]
[Estimating the DOA of speakers and speech signals are a wide-ranging problem of interest in acoustic signal processing. From the different literatures, it is concluded that beamforming based on optimization for DOA estimation is advantageous. Significant knowledge about the MA is essential...
