Progress of Electro-Acoustic Technology( Continued)
YANG Jun;Key Laboratory of Noise and Vibration Research,Institute of Acoustics, Chinese Academy of Sciences;
The latest progress of electro-acoustic technology is presented including new loudspeaker,audio signal processing,acoustic focus and replay. The new loudspeaker includes high directivity parametric array loudspeaker and all-digital audio signal processing technologies. The audio signal processing technology includes loudspeaker system balancing,virtual bass,stereo enhancement and artificial reverberation technology. The acoustic focus and replay introduce the directional acoustic radiation based on the loudspeaker array signal processing and spatial sound field technology.
