When exposed to loud noise ends of nerve fibers fade, which violates their relationship with the hair cells in all synapses (specialized zones of contact between the processes of nerve cells and other excitable and non-excitable cells, providing the transmission of information signal). According to study author Dr. Charles Lieberman, every time when a person is exposed to very loud sounds, some of its nerve fibers fade.

If this happens several times, the person is unlikely that the notice, but eventually hearing loss   begins to progress. This is particularly dangerous for young people who regularly attend a variety of noisy Events. (READ MORE)
