STC stands for Small-scale Technology Certificate. It is a scheme developed by the Federal Government to encourage more people to install renewable energy systems and to make it more affordable for everyone. You might find some people refer to them as a rebate. However this is really untrue.
The STC rating is calculated in accordance with ASTM E413 (Originally published in 1970). It was created to provide a single number rating for interior building partitions that are subjected to noises from speech, television, radio, office equipment and other mid to high frequency noise sources.he higher the number, the better the noise isolation. The STC rating is calculated over the frequency range of 125 to 4000 hertz. The rating is calculated by comparing the measured sound transmission loss to a reference contour curve. The STC rating must only be assigned to specimens tested in a laboratory.
