Web the oitc rating represents transmission loss results from 80 to 4,000 hz using a different mathematical equation than the stc rating. For glazing that is installed within a building interior, the sound transmission class (stc) rating may be a more appropriate Web outdoor/indoor transmission class (oitc) and is an integer rating of how effectively an exterior building element attenuates, or reduces, airborne noise from outside to inside a building. How to measure stc rating? Web transmission class (oitc) rating describes its approximate decibel level reduction of sounds such as those of roadway and rail traffic, and of nearby aircraft takeoffs. A higher sound transmission class rating indicates more effective sound insulation than a lower rating.
