The State Key Laboratory of Sound Field and Sound Information (Institute of Acoustics, Chinese Academy of Sciences) is a laboratory focusing on sound field and sound information, which was established in 1987.
Sound field and sound information key state laboratories [1] rely on Institute of Acoustics, Chinese Academy of Sciences 。 In 1987, it was approved by the State Planning Commission. It was completed at the end of 1989. In February 1990, it passed the national acceptance. In September 1990, it was officially opened to the outside world. Since its establishment, the laboratory has participated in four national assessments (1991, 1994, 2000 and 2005), all of which were rated as "excellent laboratories". At the 10th and 20th anniversary of the National Key Laboratory Program, the laboratory was rated as "Advanced Collective of the National Key Laboratory Program", and Academician Zhang Renhe was rated as "Advanced Worker of the National Key Laboratory Program". The State Key Laboratory of Sound Field Sound Information, closely focusing on major national needs and key scientific and technological issues in the field of acoustics, grasps the development trend of the world's scientific frontier and interdisciplinary development. It is China's research in sound field sound information and digital signal processing closely related to it, especially in marine acoustics and related scientific frontier fields, A base for high-level basic research and applied basic research, a base for high-level international exchange and cooperation research, and a base for attracting and gathering outstanding scientific and technological talents and cultivating young scientific and technological talents. Facing the world's scientific frontier and national strategic needs in three disciplines, namely underwater acoustics, ultrasonics and aeroacoustics, the laboratory focuses on studying the interaction between sound waves and materials, exploring the laws of the influence of material properties on the sound field and the methods of obtaining information related to material properties from the sound field, and paying attention to the close combination of sound field physics and sound information extraction, signal processing theory and technology, Pay special attention to the theory and method research on acoustic detection and recognition, continue to carry out basic, strategic and forward-looking basic research and applied basic research, and actively promote the transformation and application of applied basic research achievements to strategic high-tech.
