Headache, tachycardias, agitation, fast breathing and blinking are some of the symptoms. Muscles also may become tense.

But if a person over 85 decibels is exposed for a long time may have cardiovascular risks. It is also possible that increased levels of cholesterol, triglycerides and blood glucose register.

After the watershed passage of the United States Noise Control Act of 1972,other local and state governments passed further regulations. A noise regulation restricts the amount of noise, the duration of noise and the source of noise. It usually places restrictions for certain times of the day.Although the UK and Japan enacted national laws in 1960 and 1967 respectively, these laws were not at all comprehensive or fully enforceable as to address generally rising ambient noise, enforceable numerical source limits on aircraft and motor vehicles or comprehensive directives to local government.
