Sound Proofing: STC and OITC Rating
When it comes to sound, sound control is essential to living a happy, healthy life. People expect a certain level of privacy and silence, especially in their homes. Therefore, in recent years sound control standards have become a part of building codes. Part of an overall sound control strategy is to choose doors that absorb and block noise, rather than transmit it.
Sound rating systems are critical for optimal building design and product specification. Two of the most common sound rating systems are Sound Transmission Class (STC) and Outdoor-indoor Transmission Class (OITC).
