frequency Road traffic noise levels are usually quoted in terms of dB(A) and the "difference" between outside and inside noise levels (due to barriers windows walls etc) is quoted as dB(A) reduction Sound Reduction Ratings – Wall Floor Panels Precast concrete floor and wall panels (as well as other materials eg glass) are Get price

Dispelling the myths about structural steel and sound

and amplified speech A wall assembly with an STC rating of 50 db can reduce 110 db of airborne sound on one side of the wall to 60 db airborne sound on the other This is the equivalent of reducing the noise level of a rock concert to the level of normal speech (We'll stay focused on the medium- and high-frequency range but it should be noted Get price

What is a decibel and how is it measured? NEXT PAGE The decibel All of the ratings above are taken while standing near the sound Any sound above 85 dB can cause hearing loss and the loss is related both to the power of the sound as well as the length of exposure You know that you are listening to an 85-dB sound if you have to raise Get price

Noise Reduction Coefficient (NRC)

Noise Reduction Coefficient (NRC) While STC and SRC indicate how well noise passes through different materials NRC (Noise Reduction Coefficient) measures how well materials stop sound from reflecting (how much sound they can absorb) The NRC is the percentage of sound that a surface absorbs (in other words hits a surface and doesn't reflect Get price
