Mar 30, 2023 · 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.

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).

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.

Mar 7, 2025 · Sound Transmission Coefficient (STC) – otherwise known as “Sound Transmission Class” – is the golden standard that evaluates how well a barrier, be it a wall, ceiling, door, or window, reduces airborne sound.

What is Sound Transmission Class? Sound Transmission Class (STC) is a single number that describes the ability of a building material or partition to block airborne sound. STC is a laboratory test result defined by ASTM E413 for sound transmission loss testing performed according to …

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.

Sep 17, 2018 · STC stands for Sound Transmission Class. It is the ability of a product or material to reduce the transmission of sound between rooms. It measures how much sound a wall, door, window or ventilation system, for instance, will block noise from getting through to the other side.

STC stands for Sound Transmission Class, a standardized system used to measure the effectiveness of a material in blocking sound. Essentially, the higher the STC rating, the better a wall, floor, or ceiling is at isolating sound.

STC stands for Sound Transmission Class. It’s a way to rank how much sound a building partition—like a wall or ceiling—... Guide to Soundproofing & Room Acoustics

Jun 7, 2024 · Sound Transmission Class (STC) is a numerical rating used to measure how well a building material or assembly can reduce the transmission of airborne sound from one side of a partition to the other. In simpler terms, STC is a way to quantify how effective a material is at blocking sound from passing through it.
