• 

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.

• 

Limit the amount of time you listen. As the volume increases, less time is required before 

you hearing could be affected.
