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.
