Abstract: In the 21st Century, human population is experiencing the manmade plague of environmental noise from which there is virtually no escape, no matter where we are - in our homes and yards, on our streets, in our cars, at theaters, restaurants, parks, arenas, and in other public places. There are many factors, both emotional and physical, which contribute to the variation in human reaction to response. The existence of these variables prohibits defining an exact individual and community response. Exposure to noise induces fatigue, depressed mood and well-being, and decreased performance. Decreased alertness leading to accidents, injuries, and death has also been attributed to lack of sleep and disrupted circadian rhythms. Noise during sleep causes increased blood pressure, increased heart rate, increased pulse amplitude, vasoconstriction, and changes in respiration, cardiac arrhythmias, and increased body movement.
