   When using your headphones with an unfamiliar or unstable sound 

system (airplane, public access ports, etc.), make sure the volume is 
low to prevent “break-in” bursts of loud sounds.

   Keep your M-Audio headphones away from young children. This 

product includes small parts that may create a choking hazard.

   M-Audio recommends limiting the use of headphones. Different 

individuals may be impacted to a different degree by high noise 
levels (volumes exceeding 85 dB(A)). Regular exposure to loud 
headphones may be dangerous to your hearing and can cause 
permanent hearing loss.

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 115 dB(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 necessarily provide 
you with protection from potential hearing loss.
