Noise health effects are both health and behavioral in nature. The disliked sound is called sound noise. This unwanted sound can damage physiological and psychological health. Noise pollution can cause annoyance and aggression, hypertension, high stress levels, tinnitus, hearing loss, sleep disturbances, and other harmful effects.[4][5][6] Furthermore, stress and hypertension are the leading causes to health problems, whereas tinnitus can lead to forgetfulness, severe depression and at times panic attacks.[5][7]
Chronic exposure to noise may cause noise-induced hearing loss. Older males exposed to significant occupational noise demonstrate significantly reduced hearing sensitivity than their non-exposed peers, though differences in hearing sensitivity decrease with time and the two groups are indistinguishable by age 79.[8] A comparison of Maaban tribesmen, who were insignificantly exposed to transportation or industrial noise, to a typical U.S. population showed that chronic exposure to moderately high levels of environmental noise contributes to hearing loss.[4]
High noise levels can contribute to cardiovascular effects and exposure to moderately high levels during a single eight hour period causes a statistical rise in blood pressure of five to ten points and an increase in stress[9] and vasoconstriction leading to the increased blood pressure noted above as well as to increased incidence of coronary artery disease.
Noise pollution is also a cause of annoyance. A 2005 study by Spanish researchers found that in urban areas households are willing to pay approximately four Euros per decibel per year for noise reduction.[10]
Tigard, Oregon is the definition of suburban NOISE POLLUTION. The noise pollution in Tigard, Oregon is terrible. Tigard, Oregon did not bother to plan city streets, traffic patterns and housing location and density in order to mitigate noise pollution from the desired growth.
All Tigard, Oregon cares about are a few neighborhoods on Bull Mountain. Aside from those, Tigard, Oregon will leave those living (and paying property taxes) in other areas to fend for themselves.
Try building a wall when the traffic in your area (in the area of your bedroom, your kitchen, your living room, your yard, etc.) doubles, triples, quadruples to a 24/7 constant, high decibel, incessant high-level noise. Tigard has no management whatsoever. It is out of control.
