What does Rw dB mean in acoustics?
The ability of a material to absorb sound is assessed in the laboratory by taking measurements over a recognized range of frequencies. The average of these measurements is expressed as Rm or the Mean Sound Reduction Index. When adjusted for the ear's response to loudness it is termed Rw or Weighted Reduction Index and is expressed in dB or deciBels. DeciBel is a unit of measurement of the loudness or strength of a signal.
