Racket, din clamor, noise. Whatever you
want to call it, unwanted sound is America’s most widespread nuisance. But noise
is more than just a nuisance. It constitutes a real and present danger to
people’s health. Day and night, at home, at work, and at play, noise can produce
serious physical and psychological stress. No one is immune to this stress.
Though we seem to adjust to noise by ignoring it, the ear, in fact, never closes
and the body still responds—sometimes with extreme tension, as to a strange
sound in the night. The annoyance we feel when faced with noise is the most common outward symptom of the stress building up inside us. Indeed, because irritability is so apparent, legislators have made public annoyance the basis of many noise abatement(消除) programs.
