Determine Target STCs 3 inch 39 43 3. 030" P. WHAT IS STC? STC stands for Sound Transmission Class. The second column is the rating of the operable door. This rating is given to materials that are tested over a range of frequencies, and are proven to block sound in some capacity. The STC (Sound Transmission Class) rating is a single-num ber rating system for interio r build ing partitions and viewin g windows used to catego rize acoustic performanc e. Tested under ASTM E90, laminated outside pane consisted of either 1/8"-0. The STC rating system looks at the amount of noise mitigation provided by the assembly over a broad range of frequencies and a single number is calculated as its rating. Comparison Charts. Jun 15, 2024 · The STC ratings for windows and glass can range from 18 to 65, depending on the type and thickness of the glass. government agencies. V. The STC (Sound Transmission Class) rating is a single-number rating system for interior building partitions and viewing windows used to categorize acoustic performance. -1/8" (total 3/8" thick), 1/4"-0. Sound Transmission Class (STC) - The STC rating is a single number value quantifying the ability of a material to resist the transmission of sound. *OITC is estimate d base d on this test. However, soundproof windows can have an STC rating of 48-54 or higher, providing significantly better sound • • • • •Sound transmission Coefficient (STC) rating During general full scale wall testing, cellulose effectively reduces the airborne sound from room to room. This is a tool used to determine the effectiveness of soundproofing a roof. 5” Acoustics Assembly Number: ISS-02 STC: 43 OITC: 28 Report No. That being said, anything below an STC rating of 40 might garner comments about paper thin walls. The higher the STC rating, Class (STC) rating. For example, the STC of a 1/2” insulating glass unit (3mm/6mm airgap/3mm) is 28 and the STC rating of a 3/4” insulating glass unit (3mm/13. Each assembly has been assigned a unique refer- ence number through an index system. Jan 1, 2020 · Referring to the typical STC 30 rating chart below, STC is determined by testing sound transmission decibel loss at 16 standard frequencies from 125 to 4000 Hertz (Hz). Assemblies will be organized by STC value ranging from an STC of 40 to an STC of 57. STC Sound Transmission Class (or STC) is an integer rating of how well a building partition attenuates airborne sound. • An empty framed wall (steel studs and a layer of gypsum wallboard on each side) has an STC of approximately 35 STC ratings by up to 10. 5 inch 46 52 3 inch 48 53 3. The second column is the rating of the operable door The STC (Sound Transmission Class) rating is a single-number rating system for interior building partitions and viewing windows used to categorize acoustic performance. The first column is the rating of the door panel only; tested in a static inoperable condition to determine the sound transmission through the door. 03. It’s an integer rating that tells us to what degree a building partition (such as a wall or ceiling) reduces the force of airborne sound. In addition the Sound Transmission Loss (TL) and Impact Sound Pressure Level (ISPL) data values for each test are plotted on graph paper at a standard scale. Fire-resistant with melting point up to 2,000˚ F (1,093˚ C). • Doubling the mass of a wall assembly does not double the STC rating.

The STC and ISO RW values indicate the acoustical performance ratings, with higher numbers indicating better sound components. STC primarily measures airborne sound; however, structure borne sounds are also measured in the low frequencies below 300 Hz. In sum, STC tells you how much a ceiling or wall might stop sound. Implementation of the appropriate rating system is important because OITC and STC ratings are not linearly related, and the achievement of a strong STC rating does not necessarily correlate with a similar OITC rating. A rating of 40 would likewise correlate with a volume reduction to approximately 1/16th of the original level (1/2)^4 = 1/16). S. frequencies. B. It is intended as a quick screening tool to compare different wall or fl oor assemblies.
