INFORMATION REQUIRED BY E.P.A.
The level of nose entering a person's ear, when hearing protection is worn as directed, is closely approximated by the difference between the A-weighted
environmental level and the NRR
Example:
1. The environmental noise level at the ear is 100 dB (A).
2. The NRR is
23
decibels (dB)
3. The level of noise entering the ear is approximately equal to 77 dB (A).
CAUTION:
For noise environments dominated by frequencies below 500 Hz. the C-weighted environmental noise level should be used. Improper fit of
this device will reduce its effectiveness in attenuating noise. Although hearing protectors can be recommended for protection against the harmful effects
of impulse 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 impulse noise such as gunfire.
NOTE: The Noise Reduction Rating is derived from testing procedures at an independent laboratory and in accordance to acceptable ANSI standards.
Actual noise reduction can vary from laboratory results as labelled Protection is maximised when proper protector is selected for application.
7. SPARE PARTS AND ACCESSORIES
Two easily replaced cushions and damping pads. The replacement cushions are easily installed with a simple press-and-snap function. It is recommended
that the hearing protector cushions and damping pads
are replaced with 6 month intervals
Is in order to guarantee continued good noise attenuation,
hygiene and comfort.
Clean disposable headset protective pads – Cool II:
The ultimate and comfortable alternative when using headsets in dirty environments or in extreme heat. Clean is a disposable hygiene pad that is applied
directly on the hearing protector cushions. Package consists of 100 pairs of pads.
