Accuracy of Prediction Methods for Sound Transmission Loss

Abstract [586] There are various methods for predicting the sound transmission loss of walls and floors that can be used by noise control engineers. It is important to know how accurate these methods are for typical constructions used in Building Acoustics. Results are presented for a number of different constructions showing how accurately the results of predictions match experimental laboratory results. The results will show the accuracy over the frequency range 50 to 5,000 Hz. Both single and double partitions will be discussed.
