Safe Listening
Use of these earphones at full volume on portable music players
is within OSHA Permissible Exposure Limits (PEL) for 10 ½ hours
per day (52 ½ hours per week). Because of the noise-isolating
properties of the eartips (NRR=22 dB for 3-flange eartips and
NRR=27 dB for foam eartips) ambient (industrial) noise (up to
102 dB for 3-flange eartips or up to 108 dB for foam eartips) has
a negligible effect on overall noise dose.
The SAFETY Earphones have been tested in accordance with the
EN50332-2:2013 sound system equipment: Headphones and
earphones associated with personal music players — Maximum
sound pressure level measurement methodology.
The acoustic output of the SAFETY Earphones is more than 20 dB
below the maximum limit in EN 60950-1/A 12:2011 Information
technology equipment - Safety -- Part 1: General requirements.
Because of the noise-isolating properties of the eartips (SNR 27 to
28), ambient environmental noise up to 108 dB has a negligible
effect on overall noise dose.
