M-AUDIO IE-40 Manuel D’Utilisation

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:

90

8 hours

95

4 hours

100

2 hours

105

1 hour

110

30 minutes

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.
