- OSHA, the Occupational Safety and Health Administration, regulates noise levels in workplaces, with implications for headphones.
- OSHA compliance for headphones refers to noise reduction ratings (NRR) and the capacity to keep noise exposure below 85 dB.
- The higher the NRR, the more noise reduction a headphone provides.
- Various options for OSHA compliant headphones and earbuds are available, offering a range of features and prices.
In an increasingly loud world, protecting one’s hearing is more important than ever, especially in workplaces with high noise levels. This is where OSHA (Occupational Safety and Health Administration) compliant headphones come in. Despite a common misconception, OSHA doesn’t directly approve headphones. Instead, headphones gain OSHA compliance through noise reduction ratings (NRR) guided by OSHA rules.
Understanding OSHA and Noise Reduction Ratings (NRR)
OSHA, part of the US Department of Labor, ensures health and safety regulations are maintained within the workplace. In the context of noise, OSHA mandates employers to have a hearing conservation program if noise levels exceed 85 decibels (dB) over an eight-hour shift, as sustained exposure to noise above this level can lead to hearing damage. The permissible exposure time halves with every 5dB increase in noise.
Noise Reduction Rating (NRR) is a critical factor when discussing OSHA compliant headphones. Developed by the Environmental Protection Agency (EPA), NRR measures a device’s ability to reduce noise exposure. The higher the NRR, the better the noise reduction. However, calculating an NRR number isn’t straightforward as the reduction isn’t direct. A complex calculation involving subtracting 7 from the NRR number and dividing by two is involved, with alternative methods provided by OSHA.
The Search for OSHA Compliant Headphones
The technical details surrounding NRR and OSHA compliance can make finding the right pair of OSHA compliant headphones daunting. However, a good rule of thumb is to remember that a higher NRR usually translates to better noise reduction.
