Cut the Noise Concrete Construction Magazine

Oct 02, 2009  Noise is measured as a “dose” that is calculated as a combination of the noise level and duration of the noise. The level is measured using the decibels scale, which is abbreviated as dB. This scale is a logarithmic scale meaning the noise level doubles with each 10 dB increase—at a level of 80 dB normal conversation is possible, while at ...
