JBUDDIES PROTECT

KIDS HEARING PROTECTION

FITTING INSTRUCTIONS

NOISE REDUCTION RATING (NRR)

Although hearing protectors can be recommended for protection against the harmful effects of impulsive noise, the Noise Reduction Rating

(NRR) is based on the attenuation of continuous noise and may not be an accurate indicator of the protection attainable against impulsive

noise such as gunfire.

The level of noise entering a person's ear, when hearing protector is worn as directed, is closely approximated by the difference between the

A-weighted environmental noise level and the NRR.

ATTENUATION DATA (ANSI S3.19-1974)

Place the earmuff on the head with the band resting on top of the head.

1

Pull out the earcups and place them over your ears so that the ear cushions fit snugly.

2

It is important that the cups fully enclose the ears and that the cushions exert equal

pressure around the ears.

3

Adjust the height of both earcups for comfort and a good seal. Do this by sliding the

earcup up or down while holding the headband in place.
