A theoretical model is developed to predict the transmission loss of a clamped rectangular plate with an array of lumped masses attached, and is compared with experimental measurements. An increase in the transmission loss of the plate was observed over approximately two octaves, in excess of that expected due to the effect of the ‘smearing’ the added mass over the plate, and these results compared well with a theoretical model. A laser vibrometer was used to measure the average velocity of the plate and the measured results compared favourably with theoretical predictions.
