Caution! Avoid potential hearing loss
Damage to hearing occurs when a person is exposed to loud 
sounds over time. The risk of hearing loss increases as 
sound is played louder and for longer durations. Prolonged 
exposure to loud sounds (including music) is the most 
common cause of preventable hearing loss. Some scientific 
research suggests that using portable audio devices, such as 
portable music players and cell phones, at high volume 
settings for long durations may lead to permanent 
noise-induced hearing loss. 
This includes the use of headphones (including headsets, 
earbuds, and Bluetooth
®
 or other wireless devices). 
Exposure to very loud sound has also been associated in 
some studies with tinnitus (a ringing in the ear), 
hypersensitivity to sound, and distorted hearing. Individual 
susceptibility to noise-induced hearing loss and potential 
hearing problem varies. Additionally, the amount of sound 
produced by a portable audio device varies depending on the 
nature of the sound, the device settings, and the headphones 
that are used. As a result, there is no single volume setting 
that is appropriate for everyone or for every combination of 
sound, settings, and equipment. 
You should follow some common sense recommendations 
when using any portable audio device: 
• 
Always turn the volume down before plugging the earphones into 
an audio source. 
• 
Set the volume in a quiet environment and select the lowest 
volume at which you can hear adequately. 
• 
Be aware that you can adapt to higher volume settings over time, 
not realizing that the higher volume may be harmful to your 
hearing. 
• 
When using headphones, turn the volume down if you cannot 
hear the people speaking near you or if the person sitting next to 
you can hear what you are listening to. 
• 
Do not turn the volume up to block out noisy surroundings. If you 
choose to listen to your portable device in a noisy environment, 
use noise-cancelling headphones to block out background 
environmental noise. By blocking background environment noise, 
noise cancelling headphones should allow you to hear the music 
at lower volumes than when using earbuds.
