Industrial noise control generally involves the replacement of noise-producing machinery or equipment with quieter alternatives. For example, the noise from an air fan may be reduced by increasing the number of blades or their pitch and decreasing the rotational speed, thus obtaining the same air flow.
What do you mean by industrial noise?
Occupational noise is the amount of acoustic energy received by an employee’s auditory system when they are working in the industry. Occupational noise, or industrial noise, is often a term used in occupational safety and health, as sustained exposure can cause permanent hearing damage.

What are the sources industrial noise pollution?
Industrial machinery and processes are composed of various noise sources such as rotors, stators, gears, fans, vibrating panels, turbulent fluid flow, impact processes, electrical machines, internal combustion engines etc. In many countries, noise-induced hearing loss is one of the most prevalent occupational diseases.
How is industrial noise measured?
The most common instruments used for measuring noise are the sound level meter (SLM), the integrating sound level meter (ISLM), and the noise dosimeter. Most accurate for personal noise exposures, and is worn by the worker.
What is the cause of industrial noise?
Causes of Industrial Noise Pollution The three most damaging sources of noise pollution in an industrial setting are machinery, construction, and vehicles. Similarly, construction workers, blasting, bulldozing, quarrying, and various other similar activities can create a high intensity of noise pollution.
How do factories reduce sound?
Industrial Noise Treatment Options
- Sound Absorbing Wall Treatments. When high-noise machines are placed up against walls in the factory, sound absorbing wall treatments can provide noise reduction.
- Widely Spacing Machines.
- Closely Spacing Machines.
- Installing Enclosures to Contain Machine Noise.
How can you control or manage noise pollution?
How to Reduce Noise Pollution?
- Turn off Appliances at Home and offices.
- Shut the Door when using noisy Machines.
- Use Earplugs.
- Lower the volume.
- Stay away from Noisy area.
- Follow the Limits of Noise level.
- Control Noise level near sensitive areas.
- Go Green by planning trees.
What are the effects of industrial noise?
Many studies in occupational settings have indicated that workers exposed to high levels of industrial noise for 5– 30 years have increased blood pressure and statistically significant increases in risk for hypertension, compared to workers in control areas (Passchier-Vermeer 1993).
What are the 3 elements of noise?
These are voice, ambience (or effects) and music. This is an incredibly broad way of classifying the millions of different sounds that we hear during our lives.
