Hi, This credit require to evaluate the sound isolation performance of constructions using STC rating which is very common in US. Our project is in Europe where STC rating is not use. To evaluate sound isolation performance, the local equivalent used is weighted sound reduction index from Standard ISO 140 series. As for room noise level the credit accepts local equivalent, I was wondering if it was possible to use weighted sound reduction index instead of STC? Does anyone knows about it ?
