Hearing protection prevents hearing loss in loud workplaces, saving your employees’ hearing, lost work, time and money. Don’t risk damaging your employees hearing ability, let them know that you put their safety first!
To better understand the type of hearing protection you should buy, the Environmental Protection Agency defines Noise Reduction Rating (NRR) as the measurement, in decibels, of how well a hearing protector reduces noise. The higher the NRR number the greater the noise reduction. When dual protectors are used, the combined NRR provides approximately 5 – 10 decibels more than the higher rated of the two devices. For example, using disposable ear plugs (NRR of 29 decibels) with ear muffs (NRR 27) would provide a Noise Reduction Rating of approximately 39 decibels.
Excessive noise is defined as 85-90 decibels or more over an 8 hour period.
Examples of noise levels considered dangerous by experts are: a rock concert, firearms, lawnmower, firecrackers, headset listening systems, motorcycles, tractors, power tools and industrial machinery. All can deliver sounds over 90 decibels and some up to 140 decibels.
