Noise and Impact Hammers - American Piledriving

Measuring noise: Noise can be measured using a decibel meter. The name comes from Alexander Graham Bell and the unit of measurement is called- the bel. Usually the value in bels is multiplied by ten and the sound level is expressed in decibels (dB). More advanced devices are being used to determine the type of sound coming from impact pile hammers.

How to Make Noise Calculations with Decibels - Womack

dB power = dB pressure + 20 log distance (feet) - 2.5 dB. The factor -2.5 dB is an approximation to take care of moderate sound reflections from walls. Example: Find the dB noise power of a pump from a meter reading of 87 dB pressure taken 9 feet from the pump. Solution: dB power = 87 + [20 × 0.954] - 2.5 = 103.58 dB.

Safe Environments | Common Noise Levels

Noise is the variation of air pressure comprising compressions and rarefactions of longitudinal waves. It is the magnitude of the compressions and rarefactions that determine the noise levels. As the noise level increases the risk of Noise Induced Hearing Loss (NIHL) increases. A person can generally perceive a 1 – 3 dB change in noise levels.

Decibel Noise and Range Charts

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.
