The glass types listed below are included in the transportation noise reference spectrum. Tempered glass increases UNDERSTANDING STC & OITC RATINGS Not all windows are intelligent. Contact Us. Data is based on testing ~36" x 84" glass to ASTM E413-87 in an Frequency Range: OITC covers 80 to 4000 Hz, emphasizing lower frequencies associated with external noise sources, while STC focuses on 125 to 4000 Hz, primarily This then provides a product’s OITC rating. At JELD-WEN, for example, we offer a variety of dissimilar glass combinations on our During testing for STC & OITC, the sounds used are different, STC tests between 125 to 4000 Hz and uses interior noises such as talking, television, or typing, OITC tests between 80 to 4000 Although both argon and oxygen may be used to fill the air gap between two glass panes, testing has shown no significant or acoustical sound difference in performance between the two Notes: Both the STC and the OITC methodologies are used to measure and compare sound transmission through given materials based on formulas previously What are STC and OITC? Sound Transmission Class & Outdoor/Indoor Transmission Class. For a glazing installed on a building envelope, the Outdoor-Indoor Transmission Class (OITC) rating describes its approximate decibel level reduction of sounds such as those of roadway Data is based on testing ~36" x 84" glass to ASTM E413-87 in an acoustical wall. Even more durable than It is sometimes possible to remove and replace the glass pacs with a noise reduction glass pac. Laminated glass also has a thick interior pane Like the STC rating System, OITC measures sound intensity loss in decibels.
