Avoid potential hearing loss.Damage to hearing occurs when a person is exposed to loudsounds over time. The risk of hearing loss increases assound is played louder and for longer durations. Prolongedexposure to loud sounds (including music) is the mostcommon cause of preventable hearing loss. Some scientificresearch suggests that using portable audio devices, such asportable music players and cell phones, at high volumesettings for long durations may lead to permanentnoise-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 insome studies with tinnitus (a ringing in the ear),hypersensitivity to sound, and distorted hearing. Individualsusceptibility to noise-induced hearing loss and potentialhearing problem varies. Additionally, the amount of soundproduced by a portable audio device varies depending on thenature of the sound, the device settings, and the headphones
