On a typical day, a concrete mixer is pouring the driveway, contributing 85 dB. While the concrete mixer is on, so is an air compressor that contributes another 80 dB. And while concrete is being poured and the air compressor is on, another team member is using a concrete saw that contributes 90 dB.

Decibel Noise and Range Charts - HelpChartsFor example, a backhoe and a compressor each producing 90 dB have a combined output of 93 dB, not 180. But 93 dB is still twice as much noise as 90 dB. In other words, sound intensity doubles every 3 dB. Hearing protection should be used for any level over 85 dB and double protection for any level over 105 dB.Heavy Construction Equipment Noise Study Using Dosimetry ...420,000 U.S. construction workers are exposed to potentially hazardous noise levels above 85 dB(A).

Sound Intensity and Sound Level | Physics

The decibel level of a sound having the threshold intensity of 10 −12 W/m 2 is β = 0 dB, because log 10 1 = 0. That is, the threshold of hearing is 0 decibels. Table 1 gives levels in decibels and intensities in watts per meter squared for some familiar sounds.Construction Noise HandbookTable 9.3 Construction Equipment Noise Levels Based on Limited Data Samples - Backhoes.
