The 15th annual International Noise Awareness Day, Wednesday, April 28, 2010, takes place during Noise Action Week.
For some communities, at its most basic level, noise is considered a nuisance threat to the enjoyment of peace and quiet.
According to the International Noise Awareness Day founding organization, the Center for Hearing and Communication, continuous exposure to noise above 85 decibels can be harmful to hearing. Documented research has found noise does not have to be that loud to lead to physiological changes in blood pressure, sleep, digestion and other stress-related disorders. Studies exist also documenting the harmful effects of noise on children's learning and behavior.
