Health And Safety In Quarrying Agg-Net

Noise is regarded as unwanted sound and has the potential to interfere with communication or damage a person’s hearing. The quarrying industry is a noisy industry. The QPA3 states that typical noise levels could be between 89–108dB(A) for a primary crusher and 106–110dB(A) for hand drills. The principle health effect of being exposed to high levels of noise in the long term is noise ...

Noise NavigatorTM Sound Level Database

The tabled values are primarily A-weighted sound levels, as opposed to time-weighted average levels or L eq s. To determine exposures the user will have to factor in the total exposure time as well as the actual sound level that is present at the ear. For impulsive sounds, such as gunfire, the values are generally peak sound pressure levels (SPLs) and are so designated. A few of the sound ...

Understanding and Reducing Noise Nuisance From

Sound generated by stationary farm equipment may be considered a noise nuisance if the sound levels are higher than the ambient or surrounding background sound level. In remote rural areas, ambient sound is produced from natural sources, such as wind blowing through trees, running water, birds and insects. In urban areas, ambient sound is produced from human sources, such as road
