Study of thin panel with fluid loaded absorbers

The absorption of thin panel with fluid loaded absorbers was investigated. The general theory and approximate theory of thin panel absorbers were given; parameters of potential energy, parameters of kinetic energy and parameters of fluid loaded were proposed and calculated, which made absorption mechanism more clear and computation more simple than before. The coefficients of absorption and impedances of thin panel absorbers were obtained in use of transfer function method acoustical tube which agreed with the theoretical results very well.
