The Audio Guide System Can Keep Us Away From Noise

indistinguishable from sound, as both are vibrationsthrough a medium, such as air or water. The difference arises when the brain receives and perceives a sound.

Exposure to noise is associated with several negative health outcomes. Depending on duration and level of exposure, noise may cause or increase the likelihood of hearing loss, high blood pressure, ischemic heart disease, sleep disturbances, injuries, and even decreased school performance.

Noise exposure has increasingly been identified as a public health issue, especially in an occupational setting, as demonstrated with the creation of NIOSH's Noise and Hearing Loss Prevention program. Noise has also proven to be an occuptional hazard, as it is the most common work-related pollutant. Noise-induced hearing loss, when associate with exposures from the workplace is also called occuputional hearing loss.

Noise can come from anyone anywhere.So what we can do is stop receiving it.
