Abstract:
Some important standard research achievements in the fields of establishing and revising national standards on acoustics made by National Standardization Technical Committee on Acoustics (SAC TC 17) since its establishment in 1980 are firstly reviewed.Through 30 years' common efforts made by all the members of SAC TC 17 and the Chinese experts on acoustics,by the end of 2009,totally 166 national standard items on acoustics were built or revised, 131 presently effective national standards on acoustics attributed to SAC TC 17 are coming into existence,therefore national fundamental measurement standard system on acoustics including acoustical foundation,noise,building acoustics, ultrasonics and underwater acoustics standards is built up.Such a national fundamental measurement standard system on acoustics constitutes a comparatively complete national standard system on acoustics together with national environmental protection standards,such as sound environmental quality,noise emission etc standards,and engineering construction standards,as well as electrical acoustics and audio-video standards etc.Finally,considering the standard research works to be made by SAC TC 17,the details of national fundamental measurement standard system on acoustics to be developed is presented.It may be expected that as the issue of these national standards in succession,the national standard system on acoustics will be much more perfect in the future.
