= Hearing Protector Fit-Testing = Hearing protector fit-test determines how effective a hearing protection device is for an individual when worn correctly. This is typically carried out using one of the available fit-testing hardware and software systems. The effectiveness is measured as a personal attenuation rating (PAR) which is subtracted from the known noise exposure to estimate the total noise exposure a single person has to noise when wearing the tested hearing protection device.

Hearing protection such as earplugs or earmuffs must be worn correctly to be protected from noise. Correct use of hearing protection includes:


 * Choosing the most appropriate hearing protection device, both with appropriate noise reduction rating (NRR) and appropriate fit for the individual.
 * Wearing or inserting the hearing protection device correctly so it seals your ear canal, using the "roll-pull-hold" method for foam earplugs, and ensuring ear muffs create a seal around each ear.

Fit-testing hearing protection ensures both an appropriate choice of hearing protection and allows for the professional administering the fit-test to train proper techniques for wear.

Personal Attenuation Rating
Similar to a Noise Reduction Rating (NRR) required on hearing protection devices in the United States, a Personal Attenuation Rating (PAR) is subtracted from the measured noise exposure to estimate the total noise exposure an individual is receiving when wearing hearing protection. However, the PAR is regarded as more accurate than the NRR because it is calculated per individual and per hearing protection device, while NRR is a generalized estimate of potential sound reduction based on the protection provided to a small population of people.
