Paper Abstract: Discusses how it affects human behavior and health. Exposure to noise as a public health risk. Environmental noise and its effect on hearing. Rising community noise levels. Exposure to transit noise; physiological responses. Discusses findings of several studies in negative impact of noise on schoolchildren, women and men. Need to reduce environmental noise.
Paper Introduction: How noise affects human behavior
Noise is sound which is unwanted, either because of its effects on humans, its effect on physical equipment, or its interference with the detection of other sounds (Cannella, Meconi, Percoco, Comi and Graziani, 2000). It is part of environmental pollution, and under certain circumstances, can cause problems for the general population. Unsuitable exposure to noise for even short periods of time is responsible for symptomatology involving the ear, cardiovascular, muscular and digestive systems via the connection between the central and the autonomous nervous systems.
Exposure to noise constitutes a risk to public health, and there is sufficient scientific evidence that noise exposure can induce hearing impairment, hypertension, ischemic heart disease,
