摘要: Abstract The sound transmission through an infinite sandwich panel with a constrained viscoelastic damping layer is analyzed. Expressions for the loss ( TL ) and coincidence frequency are derived in terms of core parameters incidence pressure angle. Results show that has better characteristics than homogeneous elastic equivalent weight.
