<br /> Clearly acceptable: The noise exposure is such that

<br /> out with essentially no interference from aircraft noise. ..

<br /> ments are pleat.) ... '

<br /> Normally acceptable: The noise exposure is great enough
<br /> to be of some concern, but common building constructions will
<br /> make the ,indoor environment acceptable, even for sleeping ,.
<br /> quarters. (Residential areas: the outdoor environment will
<br /> be reasonably pleasant for recreation and play.)
<br /> Normally unacceptable: The noise exposure is signifi-
<br /> cantly more severe so that unusual and costly building con-
<br /> structions are necessary to ensure adequate performance of
<br /> •, activities. (Residential areas: ' barriers must be erected
<br /> . .
<br /> between the site and prominent noise sources to Make the
<br /> outdoor environment tolerable.) -
<br /> Clearly unacceptable: The noise exposure at the site
<br /> is so severe that construction costs to make the indoor
<br /> environment acceptable for performance of activities would
<br /> be prohibitiye. (Residential areas: the outdoor enriironment
<br /> Ft would be intolerable for normal residential use.)
