What is the Difference Between Noise Cancellation and Noise Suppression?

Noise cancellation looks for a frequency you do not want and adds a second sound specifically designed to cancel the first noise. Noise suppression allows all noise to be heard but at safe dB’s allowing the user to maintain awareness of their surroundings whilst still being able to hear clearly the information being relayed.

What is the NRR?

Hearing protection ratings are often referred to as Noise Reduction Ratings (NRR). 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.
