2023年3月30日 · When people are evaluating building materials and acoustical products for sound reduction, they rely on the sound transmission class or STC rating of the product. By understanding this rating of materials, we know how much sound will be blocked from going through those materials.

Discover stc’s vision and core values as we strive to become a customer-centric company, continuously improving and adopting the best solutions for our clients.

Sound Transmission Class (or STC) is an integer rating of how well a building partition attenuates airborne sound. In the US, it is widely used to rate interior partitions, ceilings, floors, doors, windows and exterior wall configurations.

Sound Transmission Class (STC ) is an integer rating of how well a building partition attenuates airborne sound. In the USA, it is widely used to rate interior partitions, ceilings and floors, doors, windows and exterior wall configurations (see ASTM International Classification E413 and E90).

2024年11月7日 · As of October 2024, each STC is valued at approximately $38-$40. The price can fluctuate based on supply and demand, but the STC clearing house caps the value at $40 (excluding GST). It’s important to check the current market …

Illustrated sound control insulation to reduce sound transmission between adjacent rooms such as offices, conference rooms, service areas and the like. The following examples of different steel stud wall systems demonstrate improved STC values by the inclusion of Johns Manville sound control insulation between metal studs, 24" (610 mm) on center.

2024年11月17日 · The Sound Transmission Class (STC) value is a measurement used to evaluate the sound insulation properties of different materials and building structures. It quantifies the ability of a material or assembly to block sound from traveling through it, providing an indication of how well it can reduce noise transmission between spaces.

2024年6月15日 · STC is an acronym for Sound Transmission Class, a numerical measure used to indicate the effectiveness of a partition in attenuating airborne sound. It is expressed on a scale of 0 to 100, with higher numbers indicating greater soundproofing capabilities.

2023年5月19日 · Sound Transmission Class (STC) ratings show how well a wall assembly diminishes airborne sound traveling from one room to another. Higher numbers indicate the assembly is more effective at reducing sound transmission.

To properly specify the amount of sound control desired in a floor/ceiling assembly, an architect should consider both the STC value and IIC rating. The STC value is a measurement of the ability of a floor/ceiling to reduce the transmission of airborne noise such as voices.
