Hearing Protection Ratings Explained
Those who are well informed about on-the-job noise exposure and the dangers therein are typically familiar with the term “hearing protection ratings.” However, there are still many employers and employees who have not been adequately informed about hearing protection ratings and noise reduction ratings. Individuals who are not familiar with the aforementioned terms may benefit from reading this brief explanation. By remaining informed about occupational noise exposure and related concepts such as hearing protection ratings and noise reduction ratings, employers and employees alike can intentionally pursue safety without reducing work efficiency.
What Are Hearing Protection Ratings?
Hearing protection ratings are often referred to as noise reduction ratings. Essentially, a noise reduction rating is a guideline or standard that acts as an absolute reference concerning the amount of predicted hearing protection a certain piece of equipment will supply at any given time in an overly noisy work atmosphere. Most hearing devices are designed to decrease the amount of noise exposure with the intention of creating a safer working environment for employees.
Noise reduction ratings are measured in decibels (a unit of measurement used to classify how powerful or dense a certain sound is); for instance, a certain device may be screened to discern how great a potential it may hold for reducing decibels. This screening is often performed during experiments within scientific laboratories.
