Important Monster® Performance and Safety TipsListen ResponsiblyTo 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 |
| Quite 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 125dB |

"....a typical person can safely listen to an iPod for 4.6 hours per day at 70% volume."
"....knowing the levels one is listening to music at, and for how long is extremely important."

Use Responsibly Do not use headphones when it's unsafe to do so - while operating a vehicle, crossing streets, or during any activity or in an environment where your full attention to your surroundings is required.
It's dangerous to drive while wearing headphones, and in many places, illegal because it decreases your chances of hearing life-saving sounds outside of your vehicle, such as another car's horn and emergency vehicle sirens.
Please avoid wearing your headphones while driving. Use one of Monster's FM transmitters to listen to your mobile media devices instead.
