A method for determining the acoustic properties of thin plates is described. Existing theoretical expressions are used to calculate transmission and reflection coefficients for sound waves striking the plates at arbitrary angles of incidence. Theory is substantiated by experimental data, and refined values for absorption coefficient and shear velocity are obtained by combining theory and experiment. Materials tested were Absonic-A, plexiglass, and polyethylene. Subject Classification: 30.30, 30.50, 20.30. [ABSTRACT FROM AUTHOR] |
