Important Monster® Performance and Safety Tips

Listen Responsibly

To avoid hearing damage, make sure that the volume on your music player is turned down before connecting your headphones. After placing headphones in your ears, gradually turn up the volume until you reach a comfortable listening level.

Noise levels are measured in decibels (dB), exposure to any noise at or above 85 dB can cause gradual hearing loss.

Monitor your use; hearing loss is a function of loudness versus time. The louder it is, the less time you can be exposed to it. The softer it is, the more time you can listen to it. Refer to the chart* below.

This decibel (dB) table compares some common sounds and shows how they rank in potential harm to hearing.

SOUND	NOISE LEVEL (dB)	EFFECT
Whisper	30	Very quiet
Quiet Office	50–60	Comfortable hearing levels are under 60 dB
Vacuum Cleaner, Hair Dryer	70	Intrusive; interferes with telephone conversations
Food Blender	85–90	85 dB is the level at which hearing damage (8 hrs.) begins
Garbage Truck, Cement Mixer	100	No more than 15 minutes of unprotected exposure
		recommended for sounds between 90-100 dB
Power Saw, Drill/Jackhammer	110	Regular exposure to sound over 100 dB of more than 1 minute
		risks permanent hearing loss
Rock Concerts (varies)	110–140	Threshold of pain begins around 125 dB
