Noise. I hate noise. What is noise?

I've heard noise described as any unwanted sound. So, one woman's noise is another woman's operetta. I'm sick of airplane noise, that's for sure. I keep one tab of Firefox open to http://www.macnoise.com/complaint and when I'm at the computer, if I hear an airplane above the sound of the fan I keep on as white noise I complain about it. Takes about 3 seconds. Only thing is, they won't let you complain more than once per minute, and sometimes the planes fly over more frequently than that. So I complained about that. Life is kvetching. Here's a taste of what Wikipedia has to say about the health effects of noise, now well-documented:

Noise health effects

Roadway noise is a major source of exposure

Noise health effects are the health consequences of elevated sound levels. Elevated workplace or other noise can cause hearing impairment, hypertension, ischemic heart disease, annoyance, sleep disturbance, and decreased school performance. Changes in the immune system and birth defects have been attributed to noise exposure, but evidence is limited.^[1] Although some presbycusis may occur naturally with age,^[2] in many developed nations the cumulative impact of noise is sufficient to impair the hearing of a large fraction of the population over the course of a lifetime.^[3][4] Noise exposure has also been known to induce tinnitus, hypertension, vasoconstriction and other cardiovascular impacts.^[5]

Beyond these effects, elevated noise levels can create stress, increase workplace accident rates, and stimulate aggression and other anti-social behaviors.^[6] The most significant causes are vehicle and aircraft noise, prolonged exposure to loud music, and industrial noise .
