measurements of noise levels taken near a busy highway and on the outside of a building wall may show that average noise levels are around 80 dB(A), yet when measured on the inside of that building only record 50 dB(A). The difference between the two levels is 30 dB(A), so an approximate noise reduction rating for that wall would be 30 dB(A).

Decibel (dB) Range Charts - Click to Enlarge. Decibel (dB) is the unit used to measure a sound's strength. The decibel scale is not linear but logarithmic. This means that noise levels can't be added directly like other numbers. On the decibel scale, the smallest audible sound (near total silence) is 0 dB. A sound 10 times more powerful is 10 dB.
Concrete Recycling • Breaking, removing and crushing hardened concrete from an acceptable source. • Old concrete pavements often are excellent sources of material for producing recycled concrete aggregate (RCA). • This webinar focuses primarily on RCA from existing pavements (not mixed C&D waste). 6
