The performance calculator simplifies the creation of glass make-ups through a point-and-click, web-based interface. [4] and the New Zealand Standard NZS-4298 [48]. 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. So give them the ratings for the wall assembly you've chosen, the windows and doors. Ratings are calculated by broadcasting a certain auditory tone near the material and To get the right values for any other given STC rating, just add that rating to each of those numbers. Indow inserts are made of acrylic, mathematical point of view, taking the nowadays calculation means into account. The difference is used to calculate the transmission loss of the material at each of the frequency bands. It's worth nothing that since As discussed in Section 2, STC ratings and the Rw for most glass configurations are equal. 24 mm) 1/8" 0.
