Facts About Industrial Noise Control In Florida



Filed under : Environment

Noise from industries is something that is almost unavoidable as long as machines are made use of. It however has become a serious issue over time due to the fact that the hearing ability of industrial workers may be adversely affected. In fact, the ears of such people may be permanently affected due to such exposure. It therefore is important that strategies are put in place to prevent such effects. There are many techniques used for industrial noise control in Florida.

One of the techniques employed is the use of damping. This is used in hoppers, chutes, panels, machine guards and conveyors among others. With this technique, there are two basic ways of achieving control. The first way is through unconstrained layer damping in which a layer of bitumastic material of high damping is stuck to the surface. The second option involves construction of a laminate. The more effective and rugged option is constrained layer damping.

With constrained layer damping, there is either re-manufacture of steel guards or the purchase of self adhesive steel sheets. The second option makes it possible for existing components to be stuck and to cover 80 percent of flat surface areas. This results in between 5-25 dB reduction in noise. This however comes with a limitation; there will be reduced efficiency for thicker sheets. Implementation in sheets that have thickness over 3mm is not easy.

The use of fan installations is also effective. Maximum efficiency of fans coincides precisely with minimum noise. As a result, any fan installation features that tend to minimize efficiency of the fan will definitely increase sonic pollution. The most experienced examples are dampers and bends close to the fan. For fan efficiency to be at a maximum, there should at least be 2-3 duct diameters between features that may disturb flow.

When ductwork is used, there will be 10-20 dB reduction in noises that are transmitted in the air. Rather than making use of silencers, one can line the last bend in the ductwork through the use of acoustic absorbents. The absorbents may either be fiberglass or foam. Alternatively, there can be construction of simple right-angled bends constructed from absorbents and which can fit on the openings. Any duct vibrations are handled through the use of dampers.

There is the application of fan speed reduction in centrifugal flow fans and axial fans. Noise from fans is roughly proportional to the 5th power of fan speed. Therefore, small drops in speed of fans will massively reduce noises. This can be achieved by changing size of pulleys or control systems. Dampers may also be reset.

The use of electric motors can be employed in such a way that noises are greatly controlled in the industry. The majority of companies have many electric motors used on a large range of devices. Most people are however not aware of the availability of general duty motors that are up to 10 dB or more quieter than the available typical units. It is best to feed motors into the system gradually such that all replacements are quiet.

Companies should ensure that employees are protected from excessive noises. This can be achieved through the use of earplugs and a range of other protective gears. Regular medical examination helps to ensure hearing is not affected.
