Should harmful interferencebe found to occur, FDA will conduct testing to assess the interferenceand work to resolve the problem.12.

Some scientific research suggests thatusing portable audio devices, and cellular telephones, at high volumesettings for long durations may lead to permanent noise-inducedhearing loss. This includes the use of headphones (including headsets,earbuds and Bluetooth® or other wireless devices). Exposure to veryloud sound has also been associated in some studies with tinnitus (aringing in the ear), hypersensitivity to sound and distorted hearing.Individual susceptibility to noise-induced hearing loss and otherpotential hearing problems varies.
