Listen Responsibly!
Hearing health is critical to your enjoyment of
music and to your quality of life. Protect your
hearing by listening to your music in a responsible
manner that protects your long-term hearing
health.
Please review and consider the following
Occupational Safety Health Administration
(“OSHA”) guidelines regarding the maximum
time exposure to sound pressure levels before
hearing damage may occur.
OSHA has established the following noise
exposure limits:
Sound Pressure
Level dB(A)
Permissible Noise
Exposure Duration
(per day)
90 8 hours
95 4 hours
100 2 hours
105 1 hour
110 30 minutes
WARNING: Exposure to sound pressure levels
above 115dB(A) for even short periods of time
can cause permanent hearing damage.
The preceding OSHA exposure levels should be
considered maximum limits. Compliance with the
OSHA limits will not provide you with protection
from potential hearing loss. Accordingly, we
recommend never exceeding 50% of the
permitted volume on your audio playing device
and limiting your use of headphones to durations
of one hour or less per day. Decibel levels of 85
dB(A) are dangerous to your hearing and may
cause hearing loss.
