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.
