Noise Impact Study for UMore Park Sand and Gravel Resources UOFMN 103496 University of Minnesota Page 3 The following list provides a comparison of the noise levels of some common noise sources. Sound Pressure Level (dBA) Noise Source 140 Jet Engine (at 25 meters)
If you must be exposed to noise, it is recommended that you limit the exposure time and/or wear hearing protection. A three dBA increase doubles the amount of noise, and halves the recommended amount of exposure time. The following decibel levels of common noise sources are typical, but will vary.
Thunderclap, chain saw. Oxygen torch (121 dB). 120: Painful. 32 times as loud as 70 dB. Steel mill, auto horn at 1 meter. Turbofan aircraft at takeoff power at 200 ft (118 dB). Riveting machine (110 dB); live rock music (108 114 dB). 110: Average human pain threshold. 16 times as loud as 70 dB.

This resulted in the temperature of the wash water in the holding tank building up to between 25°C and 40°C (which is in the optimal range for Legionella growth). Risk factors. 11 There are a number of factors that predispose any plant of this type to the proliferation of microbes and subsequent risk to personnel:
The median difference between measured and predicted noise levels was + dB(A) ( the model over predicted by dB(A)) with a standard deviation of dB(A). Predicted noise levels at the boundary were within ±2 dB(A) of measured levels. This is considered to be a good correlation between predicted and measured noise levels.
