How are hair dryers and headphones killing your ears? - neuroscientist Sonja Pyott (University of Groningen)<unk>  <unk>  is a hearing impairment resulting from exposure to loud sound. People may have a loss of perception of a narrow range of frequencies or impaired perception of sound including sensitivity to sound or ringing in the ears. When exposure to hazards such as<unk>  occur at work and is associated with hearing loss, it is referred to as occupational hearing loss. Hearing may deteriorate gradually from chronic and repeated<unk>  exposure (such as to loud music or background<unk>  or suddenly from exposure to impulse<unk> , which is a short high intensity<unk>  (such as a gunshot or airhorn). In both types, loud sound overstimulates delicate hearing cells, leading to the permanent injury or death of the cells. Once lost this way, hearing cannot be restored in humans. There are a variety of prevention strategies available to avoid or reduce hearing loss. Lowering the volume of sound at its source, limiting the time of exposure and physical protection can reduce the impact of excessive<unk> . If not prevented, hearing loss can be managed through assistive devices and communication strategies. The largest burden of<unk>  has been through occupational exposures; however,<unk>  can also be due to unsafe recreational, residential, social and military service-related<unk>  exposures. It is estimated that 15% of young people are exposed to sufficient leisure<unk> s (i.e. concerts, sporting events, daily activities, personal listening devices, etc.) to cause<unk> . There is not a limited list of<unk>  sources that can cause hearing loss; rather, exposure to excessively high levels from any sound source over time can cause hearing loss.
