![]() ![]() How Does Headset Hearing Protection Change Decibel Exposure Levels? Instead of the former “one number” approach, the EPA has proposed changing the labels to indicate a range, from the minimally trained to the more proficient users, accounting for variability in usage and fit. Note: the EPA is in the process of changing NRR ratings labels. Those who are serious about hearing protection may need to consider the fact that NRR is an estimate based on what will be achieved by 98% of the population if the hearing protection is properly fit (note that fit and individuality may skew the numbers drastically – in some cases by as much as 50%). The NRR essentially functions as a “ruler” that measures how well a particular piece of hearing protection or equipment may work in real time and space. To make a long story short, Noise Reduction Ratings are a set of “rules” that are set in place to serve as an absolute point of reference for those who are serious about protecting worker hearing. OSHA noise standards, 29 CFR, require a specifically tested device with strict standards.Ĭalculate the noise level at your ear using Sensear's Hearing Protection Calculator to make sure you are meeting OSHA established permissible noise exposure limits.Ī Noise Reduction Rating, also sometime referred to under the umbrella term of “hearing protection rating,” can be a confusing concept for individuals who are just starting out in the world of hearing protection terminology. Screenings are typically conducted in controlled laboratory experiments during which devices are tested in order to determine real world capabilities. Noise reduction ratings are measured using the decibel, a standard unit of measurement used to describe how powerful or compressed a specific sound level is. Noise Reduction Rating Measurement and OSHA The higher the NRR number associated with a hearing protector, the greater the potential for noise reduction. NRR is a common method for expressing values of noise reduction or attenuation provided by different types of hearing protectors values range from 0 to approximately 30, with higher values indicating greater amounts of noise reduction. Take a look at the information below to better understand one of the most important concepts of noise protection: the Noise Reduction Rating, also sometimes referred to as the NRR. ![]() Learning as much as possible about hearing protection is a key characteristic of a well-rounded business owner, manager, or administration member. Business owners, administrators, and those who are heavily involved in businesses involving the use of heavy machinery and other loud equipment might be interested in protecting worker hearing. Many business owners are beginning to understand the importance of overly loud noise exposure on the job for employees and administrators alike. ![]()
