If a ventilation grille (vent) is to be placed in the wall and the loss must not fall below 20 dB, what is the largest allowable area Svent Assume the vent is acoustically transparent, i.e., let its acoustic power coefficient be Twent = 1. Begin by showing that transmission of the vent? transmission Svent Tn - Twall Tent-Twall Swall Two rooms share a common 12 ft x 8 ft wall (Swall = 96 ft²) that has a transmission loss of TLwall = 25 dB.
