In many countries, noiseinduced hearing loss is one of the most prevalent occupational diseases. According to a Environmental Protection Agency (EPA)/USA report in 1981, there are more than nine million Americans exposed to a daily average occupational noise level above 85 dB(A); this number has increased to about 30 million in 1990.
The relationship between noise level and exposure time that is measured in a logarithmic scale – where every 3dB(A) increase in noise doubles the risk of exposure to hearing loss. b) a noise that exceeds a peak noise level of 140 dB(C) at any time during the day. Ideally, you should keep noise levels below:
A Guide to Noise Control in Minnesota • November 2015 Minnesota Pollution Control Agency 3 Common noise concerns y Minnesota law, the MPA is empowered to enforce the state''s noise rules . Many other agencies and levels of government, however, have an important role to play in upholding the noise standards.
The noise assessment of the process plant determined that the average occupational noise levels at key working locations would meet the noise exposure target levels after implementation of the recommended noise control measures. The recommended measures were as follows: Installing acoustic blankets around the rotating equipment.

This paper presents research examining noise on dredges used in several surface mine sand and gravel operations and in the processing facilities. Results indicate that there
Overview. Loud noise at work can damage hearing. Approximately 22 million workers are exposed to hazardous noise at work. To minimize occupational noiseinduced hearing loss, the National Institute for Occupational Safety and Health (NIOSH) recommends that workers should not be exposed to noise at a level that amounts to more than 85 decibels (dBA) for 8 hours.
Aug 23, 2018· The crypto mining facility have been using large fans to cool down 9,500 mining rigs, which residents claimed created too much noise that kept them up at night. In fact, some residents said they had to move to bedrooms facing away from the facility, while others had to sleep with their windows closed even on hot summer nights to keep the noise out.
Aug 23, 2018· The problem stems from residents reports stating the facility is responsible for the noise pollution in the area. Particularly the mining farm in Hønefoss is being a burden to the locals who explain that the giant fans, which are used to cool down the 9,500 mining rigs produce unbearable noise levels.
