ENVIRONMENTAL
SOUND
AND ITS
EFFECT
ON HEALTH
Because ol the documented
efii-
cacy of music in lowering blood pres-
sure, enhancing digestive function and
reducing pain, it
has
been widely em-
ployed as a general measure to reliel
emotional and environmental slress.
However,
disorders due to sound
pol-
lution has been frequently
observed.
lt
requires
the attention of
people to
the
problem, and
to the
measures
to
be
employed
in handling
the dramatic
in-
creasing of sound.
