concrete batching plant noise levels - dcmpublicschool. The noise level is therefore expressed in decibels (dB) on the "A" scale, or dB(A). Duration of exposure is equally important. Duration is typically measured over a workday and accumulated through many years. The chart below shows different types of power tools and their noise levels.

vents, gas and oil burners, etc. Typical sound pressure levels at 1 m from a blow-off nozzle can reach 105 dB(A). Table 5.3. Increase of noise given by the sound power level difference Lw due to doubling of typical velocity (e.g. average flow velocity of gas jets, rotational speed of fans). [After Költzsch, 1984]
LAeq noise levels in general cannot exceed baseline (pre-construction) LAeq noise levels by more than 5 dB at identified noise sensitive receptor locations. While an increase of 5 dB may be noticeable, it should not present an unacceptable noise hardship condition. Baseline LAeq noise levels must be established prior to con-
