Understanding the insertion loss of the partition for audio sounds generated. 6 The effects of a thin partition on spherical waves radiated by a point monopole were also studied where the transmission loss and the insertion loss are derived analytically using the plane wave expansio. Typically all effects can be considered by using energy models and corresponding attenuation factors in frequency bands (Fig. The transmission of an audio plane wave through a thin partition is well known and the mass law is widely used to predict the insertion loss.
