What Is The Most Effective Noise Control Method?

What is acceptable noise level?

For peak noise, the national standard is a peak sound pressure level of 140 decibels.

The levels specified in the national standard are the maximum acceptable exposure levels for noise in the workplace.

However, over long periods, repeated exposure to noise between 75 and 85 decibels may be a small risk to some people..

Why is it important to reduce noise?

By reducing noise in areas where concentration is a primary condition you allow your employees to fulfill work tasks more effectively. Clearly, preventing noise from reaching too high levels is vital for businesses to protect their staff and maintain working efficiency.

What problems can excessive noise cause at work?

Over one million workers are exposed to levels of noise that put their hearing at risk, with 17 per cent suffering hearing loss, tinnitus or other hearing-related conditions as a result of exposure to excessive noise at work.

What is the best way to manage excessive noise levels?

The exposure to noise can be reduced by eliminating the source of noise (if possible), substituting the source with a quieter one, applying engineering modifications, using administrative controls, and by using protective equipment. The best way to reduce exposure to noise is to engineer it out at the design stage.

What are noise control measures?

Ways to control worker exposure to excessive noise and prevent hearing loss include using quieter machines, isolating the noise source, limiting worker exposure, or using use effective protective equipment.

How noise affects work performance?

The physical environment affects job perception, attitude, satisfaction and work ethic. An employee productivity study by British Gypsum in 2015 found reducing noise in the workplace increased the ability to focus by almost 50 percent and decreased stress levels by almost 30 percent.

What is a good noise reduction rating?

NRR Ratings The highest NRR rating for earplugs is 33, and the highest available NRR rating for earmuffs is 31. These values reflect the level of noise protection available for each device when worn alone. Combining earplugs with earmuffs can offer a NRR protection level of 36.
