Industrial Noise Control and Noise Control Products

When we talk about industrial noise control, it shouldn’t sound out of place as most industrial activities generate noise at different level. Knowing the negative impact of noise on total wellbeing, it is pertinent that we understand the concept of noise generation, exposure and control.

The Center for Disease Control (CDC) estimates that 22 million workers are exposed to potentially damaging noise at work each year. Whether you work at a sports venue, on a tarmac, or operate a jackhammer — hearing loss is preventable.

This is why this article is very important; though you may not be working directly where there is risk of exposure to excessive noise, the information you gather may be used as a guide to advise persons who are exposed and do not know how to manage the situation.

We will be considering the subject matter under some sub-headings:

What is Industrial Noise Control

Industrial noise control generally involves the replacement of noise-producing machinery or equipment with quieter alternatives, shielding noisy equipment to minimize noise, reducing employee exposure time to noise, use of personal protective equipment (PPE).

It is legally required that employers reduce their noise exposure level to as low as reasonably practicable to safe guard their employees and prevent hearing loss.

OSHA Noise Control Standard

Noise hazards are addressed in OSHA standards for recordkeeping and general industry. This section highlights OSHA standards and documents related to noise. For information on construction employment, see the construction requirements section.

Section 5(a)(1) of the OSH Act, often referred to as the General Duty Clause, requires employers to “furnish to each of his employees employment and a place of employment which are free from recognized hazards that are causing or are likely to cause death or serious physical harm to his employees”. This section may be used to address hazards for which there are no specific standards, e.g. noise in agricultural operations. Noise Standards

Sound attenuation panels:

Acoustic panels are the most popular solution for spaces where echo and reverberation create so much ambient noise, it’s difficult to hear. By absorbing sound, acoustic panels minimize sound reflections and create a more comfortable acoustic environment where speech is intelligible, and loudness is reduced.

Acoustic panels serve a very simple purpose. They introduce porous materials and density to the space. When sound waves impact hard surfaces, they reflect back into the room. The flatter those surfaces the more direct the reflections. Direct reflections can lead to audio issues in rooms, like echo and reverberation.

Perforated metal sound absorbing panels:

Perforated metal panels deliver ample sound absorption over a wide frequency range. Suitable for indoor and outdoor applications, its acoustical properties, appearance, cleanable/wipeable surface, and rugged durability make it the choice for controlling reverberant, noisy spaces where panels must resist damage from impacts, abrasion, or moisture.
