Tontine Sound Batts ACOUSTIC DESIGN MANUAL Cont. ..Sound Transmission Class of Wall Constructions TSB, when installed in the cavity of a double leaf stud wall can significantly improve the sound reduction achieved by the wall. Following are examples of the Sound Transmission Class of some building partitions with the different grades of TSB. Please note the systems referred to are as per the CSR Gyprock Manual.
