Avoid potential hearing loss.
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 cellular telephones, at high volume settings for long durations may
lead to permanent hearing loss. This includes the use of headphones (including headsets, ear
buds and Bluetooth®, or other wireless devices). Exposure to very loud sound has also been
associated in some studies with tinnitus (ringing in the ear), hypersensitivity to sound, and
distorted hearing. 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. Hence,
individual susceptibility to noise-induced hearing loss and other hearing problems can vary.
Please follow these important guidelines for hearing loss prevention:
1. Set the phone’s volume in a quiet environment and select the lowest volume for which
you can hear clearly.
