Abstract

PURPOSE: To reduce noise and improve an air ventilating effect and then miniaturize by forming the intake and exhaust air ventilating channels of an air ventilating box into a rectangular duct reducing bend and enabling incident and reflecting sound waves to interfere with each other at the corner section of the right-angled curve section in both air ventilating channels.
