Windows and doors can help block outside noises whether you live in the city or on a farm. These treatments help absorb sound waves, reducing reverberation and minimizing noise The glasses were tested for their sound transmission class (STC) and outdoor indoor transmission class (OITC). (STC/OITC), high altitudes, Sea Turtle Conservation Codes (available on The window has its own STC rating though, typically averaging about 30. Window Treatments: Utilizing window treatments like heavy curtains, blinds, or window films can provide an extra layer of sound insulation. ; All external resources referenced by OpenGlass must ensure that it can be accessed by DWM, so paths The standard IGU has 1/8” x 1/8” glass on each side. In our recent tests, an annealed IGU was used as the primary window and was tested. Quiet Line Vinyl Windows -- multiple glass lites combine to reduce sound dramatically. Glass Analytics online tools offer a comprehensive suite of engineering and analytical reports that demonstrate the advantages of high-performance glass in building facades. • A testing method conforming to ASTM E90-0913 was The STC (Sound Transmission Class) is a rating system for interior building partitions and viewing windows used to categorize acoustic performance. 1,2,3). 01 Frequency (Hz) Insulating Glass Construction STC OITC* 100 125 160 200 250 315 400 500 630 800 1000 1250 1600 2000 2500 3150 4000 5000 Sound Transmission Loss (dB) 5/8" overall - 1/8" glass, 3/8" airspace, 1/8" glass 31 26 26 23 23 20 23 19 23 27 29 32 35 39 44 47 48 41 36 43 1" overall - 1/4" glass, 1/2" airspace, 1/4" glass 35 30 27 24 29 22 22 25 30 33 35 38 40 42 42 Laminated Glass.
