health effects from electromagnetic microwaves have health effect too, i got neuropathy from microwaves and radar
Noise is unwanted and/or harmful sound, first recognized as a public health hazard in 1968.
The Noise Control Act of 1972 declared that “it is the policy of the United States to promote an environment for all Americans free from noise that jeopardizes their health or welfare.” The promise of that legislation remains unfulfilled 50 years later. Human exposure to harmful noise levels is widespread.
Major sources of noise include transportation, military aircraft and combat operations, noisy recreational vehicles, industrial machinery, recreational and leisure activities, outdoor power equipment, consumer products, electronic sirens and wind turbines.
Loud noise causes hearing loss and tinnitus and can contribute to non-auditory health problems. Chronic noise, even at low levels, can cause annoyance, sleep disruption, and stress that contribute to cardiovascular disease, cerebrovascular disease, metabolic disturbances, exacerbation of psychological disorders, and premature mortality.
Noise interferes with cognition and learning, contributes to behavior problems, and reduces achievement and productivity. The health of more than 100 million Americans is at risk, with children among the most vulnerable. Noise-related costs range in the hundreds of billions of dollars per year. Yet, the United States has no federal standards for non-occupational noise exposure. Federal standards for occupational noise exposure from the 1970s address only hearing loss as an adverse health effect and do not apply to all workers (e.g., those in agriculture and construction). Calls for action have gone largely unheeded.
Long-term exposure to traffic noise has been linked to a greater risk of heart disease. New research reveals additional clues about this connection.
Researchers studied nearly 500 adults over a five-year period and gathered traffic and aircraft noise data for each person's home address. After adjusting for other factors that contribute to cardiovascular risk (including air pollution), they found that every 5-decibel increase in the average 24-hour noise level was associated with a 34% increase in heart attacks, strokes, and other serious heart-related problems.
By using a specialized brain imaging technique, researchers showed that higher levels of noise exposure were associated with increased activity in the amygdala, the area of the brain involved in processing stress, anxiety, and fear. Excess noise also increased inflammation in the arteries, a known trigger for cardiovascular problems. The findings were published Nov. 26, 2019, in the
European Heart Journal.
People prone to heart disease should be aware that chronic noise exposure where they live may raise their risk, according to the study's lead author.

The term "noise pollution" refers to unwanted or annoying sounds that happen around you. Machinery, amplified music, noisy vehicles, and other things can cause it. If it's loud or long-lasting, noise pollution can damage your hearing. It may also lead to other health problems, including
headaches,
sleep loss, and even
high blood pressure. And it can
stress you out, make you less productive, and decrease your quality of life.
