Noise-induced hearing loss (NIHL) 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 . [ 1 ]
Adults, as well as children, experience hearing loss if the sound intensity is loud enough. According to the NIH, data from 2005-2006 estimated that 17% of teenagers had noise-induced hearing loss ...
Traumatic noise exposure can happen at work (e.g., loud machinery), at play (e.g., loud sporting events, concerts, recreational activities), and/or by accident (e.g., a backfiring engine.) Noise induced hearing loss is sometimes unilateral and typically causes patients to lose hearing around the frequency of the triggering sound trauma. [17]
Essentially, hearing aids pick up sounds in the environment, selectively amplify speech while filtering out noise, and then provide the correct frequency-specific volume for the user's hearing ...
How do hearing aids work? “Hearing aids work by sampling and collecting sound through tiny microphones,” explains audiologist Dr. Amy Sarow. These sounds are then converted into electrical ...
A common cause or exacerbating factor in SNHL is prolonged exposure to environmental noise, or noise-induced hearing loss. Exposure to a single very loud noise such as a gun shot or bomb blast can cause noise-induced hearing loss. Using headphones at high volume over time, or being in loud environments regularly, such as a loud workplace ...
