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 other potential hearing problems varies. The amount of sound produced by a portable audio device varies depending on the nature of the sound, the device, the device settings and the headphones. When using any portable audio device: • Set the volume in a quiet environment and select the lowest volume at which you can hear adequately. • 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-canceling headphones to block out background environmental noise. • Limit the amount of time you listen. As the volume increases, less time is required before your hearing could be affected. 12 NEXUS 5
