reduction of the payback period. If we talk about the air cooling, it is usually selfmade by miners. In order to reduce the noise, the regular cooling system is dismantled and silent coolers with a selfmade silencers installed. They are usually made with a 3D printer. The equipment is kept in also selfmade boxes which are designed for 12 ASICs.
Noiseinduced hearing loss entails substantial economic costs. As well as the financial cost, there is a reduction in quality of life for a person with severely impaired hearing. Mining companies recognise noise as a hazard requiring control, and most have noise control programs in place. However, in

The equipment type, specific model, equipment condition and the operation performed influence equipment noise. Equipment manufacturers began attacking machine noise problems in the late ''60s and today because of design improvements and technological advances new machines have been quieted to an acceptable level for almost every situation.
Controlling Noise on Construction Sites ... equipment the final determination often depends on whether the noise reduction justifies the extra expense. Looking at this decision another way, if the quieter machine costs 100 ... Bureau of Mines, Mining Machinery Noise Control Guidelines, 1983 . 9 Modifying Pneumatic Nail Gun Problem:
An acoustic enclosure is a closed engineering structure, designed and built for the purpose of reduction, minimisation, or attenuation of the noise generated by a particular piece of equipment or machinery. It forms a box around the said equipment and includes acoustic doors and windows and an attenuated ventilation and cooling system.
Avoiding Noise Overexposure at Underground and Surface Coal Mines, Preparation Plants and Surface Drilling Eric R. ,, Mining Hearing Loss Prevention Workshop June 2122, 2005 ... Exposure Reduction Methods Engineering noise controls: • Reduce the sound levels of the
Machine Noise Reduction – What you need to know. Machine noise is a serious problem in a factory or industrial environment. And it''s one that any manufacturer or employer needs to understand and make steps to control and reduce. The Regulations require you as an employer to assess the risks to your employees from noise at work
this chapter. Note that many of the specific noise control measures described are intended as a rough guide only. Further information on the subject can be found in ISO 11690 and in the specialised literature. Also suppliers of equipment and noise control hardware can often provide helpful noise .
Reduction of Fire Hazards on Large Mining Equipment MARIA I. DE ROSA Analysis of mining equipment fires from 1990 through 1999 reveals that there were 340 large mining equipment fires, resulting in 72 injuries and five fatalities. Many of the fires resulted in the loss of equipment and all posed potential or real risks to the operator.
Enclosures for Machinery Equipment. Specialized in industrial noise reduction, MECART can supply acoustic enclosures for even the noisiest factories. ...

Ten Ways to Reduce Noise Exposure for Your Workers. Hazardous noise levels in the workplace are a serious issue, and, if not protected against, could lead to stress, lower productivity, and, most ...
Noise can be continuous, variable, intermittent or impulsive depending on how it changes over time. Continuous noise is noise which remains constant and stable over a given time period. The noise of boilers in a power house is relatively constant and can therefore be classified as continuous. Most manufacturing noise is variable or intermittent.

Fans Noise Power Generated Noise or sound generated by a fan depends on the motor power, volume capacity, static pressure and discharged volume
Another no less important aspects of noise mitigation is the exposure of the machinery operators to cabin noise. However trivial these issues may seem – each of them is paramount for success of a particular mining project or piece of machinery." Issues with Noise across the mining industry
Protecting workers from the noise of mining. We''re helping the mining industry to protect the health of its workforce by solving the problem of noise control. Our temporary and portable noise reduction barriers provide a simple, fast and effective way to reduce noise from machinery, compressors, pumps and generators—by as much as 97%.
Noise in Mining. Most of the of exposure to noise in mining comes from the need to use heavy machinery underground, but careful design and new technology and materials can be used to minimize this. Noise assessment in mining plants need to identify noise sources in order to effectively apply the hierarchy of controls.
You can also exclude noise coming from other directions, so that it is easier to assess each source individually. Knowing how to monitor mining noise is an important part of successful mine management, but it doesn''t have to be a difficult part. With sufficient noise monitoring equipment of the right type, you can eliminate most complaints.
