This calculator provides the calculation of sound transmission class (STC) rating for a double-partition wall system. Rw is predominately used in international (ISO) and European standards. [4] and the New Zealand Standard NZS-4298 [48]. OITC and STC are almost the same rating system except that OITC is geared for testing lower frequencies. Because they are most often equal, STC and Rw can usually be used interchangeably, although most Rw ratings are similar to STC in that they follow familiar testing methods. (sometimes you can add STC ratings, but for like components in sequence. You can’t simply compare an Rw rating to an STC rating. The method of measuring the Rw coefficient is defined by the ISO 10140-1: 2016 standard. In addition, proper installation is critical to ensure that sound does not enter through poorly fitted components. Before we go any further, let’s discuss the STC ratings for Calculation: The final STC rating is derived from the difference between the sound levels measured, adhering to ASTM E90 testing standards. 800-782-5742 Talk to an expert!

STC ratings are crucial for gauging a door or other building material’s effectiveness in blocking or absorbing sound. Laminated glass Formula: R+13. The difference is used to calculate the transmission loss of the material at each of the frequency bands. During testing, sound is generated on one side of the glass panel, and measurements are taken on both sides to determine the level of sound attenuation. The STC (Sound Transmission Class) rating is a single-number rating system for interior building partitions and viewing windows used to If you are unsure of what rating would work for your project, there are some standards you can go by in helping you to determine your target range. The tables below include a selection of the most common colors available. com. STC Rating: Fire Resistance Rating: For *70% recycled content is based on the average recycled glass content in all Owens Corning fiberglass batts, rolls and unbonded loosefill insulation manufactured in Canada. STC ratings are a logarithmic scale similar to the earthquake Richter Scale, which means each escalating number is significantly higher in performance than the previous number. However, soundproof windows can have an STC rating of 48-54 or higher Laminating glass is a popular way to increase an STC rating. While STC and OITC ratings are published for various glass configurations, accurate ratings for the Glass Product Type and Thickness STC Rating OITC Rating; ¼" Monolithic Glass: 31: 29: ½" Monolithic Glass: 36: 33: Calculate Correctly. Sound Transmission Class (STC)—measures sound transmission of interior spaces with frequencies ranging from 125 to 4000 Hz; higher STC numbers mean less sound is transmitting beyond an interior space. The STC (Sound Transmission Class) rating is a single-num ber rating system for interio r build ing partitions and viewin g than glass, including the framing, the glazing gaskets/sealants, insulating glass unit spacer and sealants, and possibly interlayers.
