Controlling Noise at Factories

In the United States, workers are protected from the damaging health effects of high degree noise exposure throughout the Occupational Safety and Health Administration (OSHA) noise standards. The standards forbid workers from being exposed to noise levels exceeding an 8-hour time weighted average, A-weighted sound level of 90 decibels (denoted dBA).

Factory workers can be exposed to excessive noise levels because of employed in close proximity to high sound machines. It is not uncommon for workers in certain factories to operate in locations where the sound level exceeds 100 dBA.


The use of individual hearing protection to achieve OSHA's noise standards is considered a last resort to be used just after potential engineering and administrative noise control measures have failed to lessen the sound sufficiently. For that reason, administrative and engineering controls are of chief importance.

Noise control steps for factories must fulfill the following criteria:

They must not obstruct workers or somewhat affect just how operators make use of the system.

Noise barriers and machine enclosures may be an effective way to reduce noise; nevertheless their design shouldn't disturb workers or reduce productivity. A challenge in factories may be designing effective noise barriers that usually do not obstruct walkways or fork lift paths.

They must have the ability to resist working conditions in the factory.

Any noise control measures have to be created for that environment in that they're placed. The substances from the noise control is assembled must not be affected from dirt, oil or water if these are prevalent from the mill. Generators Enclosures have to have the ability to resist impacts when placed in regions of high traffic.

They need to keep the productivity and dependability of the machine and maybe not cause malfunctions or engineering issues.

Factory machines must work as designed after any alterations have been made into the system. The alterations must not reduce growth.

Enclosing machines with acoustically rated enclosures can be a really effective method of noise control. However, this method can restrict airflow to the equipment and also present overheating problems. Cooling systems might be required, which can themselves demand noise control systems.

They have to maintain visibility to factory machines and areas where required.

Workers frequently have to visually inspect machinery when in performance. Noise control measures must not prevent vulnerability to critical areas. Managers should be able to see into areas where employees are currently working. Transparent noise control substances should be considered in places where visibility is demanded.

Noise consultants specialize in analyzing sound degrees and designing noise control systems. A good sound consultant should have the ability to design noise control steps while fulfilling the aforementioned criteria.
