Selective conditioning for the measurement of sound transmission loss

Multiple input modelling techniques have been applied to the measurement of sound pressure and intensity in transmission loss problems. Results indicate that the power radiated by a partition or facade can be meaningfully estimated in the presence of substantial (10–25 dB) background noise levels re...

Summary:Multiple input modelling techniques have been applied to the measurement of sound pressure and intensity in transmission loss problems. Results indicate that the power radiated by a partition or facade can be meaningfully estimated in the presence of substantial (10–25 dB) background noise levels relative to a primary, multi-sine, excitation. Selective intensity estimates of the power radiated by a facade subject to random excitation also appear to be feasible.
