35 results about "Noise-induced hearing loss" patented technology

Noise-induced hearing loss (NIHL) is 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 noise occur at work and is associated with hearing loss, it is referred to as occupational hearing loss.

Apparatus for reducing the risk of noise induced hearing loss

An apparatus is disclosed for managing the joint contribution of noise exposure of the ear of a user of the apparatus from a loudspeaker of the apparatus as well as from ambient noise so that the risk of risk of noise induced hearing losses is reduced. By assessing the joint actual sound energy delivered to the ear and feeding said assessment to a model describing the accumulated risk of hearing loss due to said sound energy accumulated over a time period, an estimate of the current risk of hearing loss is obtained. When said risk estimate passes a predetermined threshold, one or more protective measures are taken.
