Examples in Context

  1. The result indicates that the board has excellent absorbing properties. Noise Reduction Coefficient(NRC) is around 0.80 ~ 1.10.
  2. The experiment results showed that when X-ray television system based on this method is regulated noise reduction coefficient, the effects of noise reduction, as well as movement of the tail of the image did not generate the feeling of transition.
  3. The noise reduction coefficient of the material is 0.6, and the sound absorption property at middle-low fre-quency is good.
  4. Many methods of noise reduction can influence coefficient of performance ( COP ) of compressors, and improving efficiency maybe cause noise increase or transformation of frequency spectrum.
