Drilling noise control is an important process especially in those industries that major in building and construction projects. Other sectors where you will likely encounter the use of these controls include the mineral exploration industries specifically gas and oil exploration. Any ethical company strives to shield the workforce and community from excessive sound energy that can damage the ear drums hence making one deaf. Techniques employed include use of sound abatement, noise absorbing wall panels and air silencers.
Human hearing is known to be great such that noise-levels cannot be accurately represented on a scale that is linear. To counter this, a logarithmic unit is used commonly known as the decibel. Sound intensity and ones length of exposure determines the risk that a persons hearing may be damaged. Sound energy received is the core determinant of damage.
Surveys can be conducted in any workplace to determine the hazard posed by the noises. The preliminary surveys should be able to identify places where the noise-level exceeds the set exposure limits. Wherever drilling machinery are used, a detailed survey should be conducted so as to provide an in-depth assessment that quantifies the noise-level, identifies the source, develop control strategies and determine the appropriate hearing protection needs.
Most controls are pegged on areas such as administration, hearing protection and engineering. One needs to clearly understand the principles that relate to noise-control. Breaking down the problem into smaller portions so as to effectively deal with each independently. These areas should include the source, transmission and reception.
To lower the levels, one should try and separate the sources. This is because combined noises produce a sound that can be 3db higher than the usual one hence posing a risk of hearing damage. Sound insulation can be used to reduce the sound energy that is able to pass. It works by reflecting most of the sound. The most common way of insulation is the use of an obstacle such as a wall or partition. One can use a porous material to absorb sound energy. This is widely applied in music recording studios. These absorbents can absorb 50 percent of the sound energy produced.
Policies set by the company administration should help reduce the sound-levels. Sound policies such as the purchase of quiet equipment can be very beneficial in solving this problem. This type of equipment is quickly gaining popularity around the world. Many manufacturers are now manufacturing and assembling such equipment as they are selling quickly and are more profitable. Routine maintenance of plant and job rotation can also help cut down on noise-levels.
There are instances where reducing the noises as the source is impossible. A sealed simple enclosure can come in handy in such a case. It reduces sound energy produced by 15 to 20 dB. Large and heavy equipment should not be mounted near a building. An elastic stable foundation such as that of rubber or springs can be used to mount the machines.
There are various drilling noise control techniques related to drifters. If down the hole hammer machines are used, they should have hydraulic drive motors. Double glass insulation in rooms can also help reduce the sound energy levels.
