WebSTC versus OITC The first measure of acoustic performance is referred to as the Sound Transmission Class or STC. This metric measures the sound levels for interior building partitions where the main sounds are people talking or office equipment. The other measure is known as the Outdoor-Indoor Transmission Class or OITC. WebGlass installed for building façade ideally possesses significant level of outdoor indoor transmission class (OITC) so it does not decrease OITC of conventional wall façade significantly. This study is about OITC of glass building in the temperature warmer than the one outlined by ASTM E-90, as it is commonly experienced in a tropical environment.
