Abstract

Critical and coincidence frequencies of panels are important in studying their behaviour under acoustic excitation Expressions for critical and coincidence frequencies of thin and thick homogeous isotropic panels are derived. Characteristics of critical frequency values in function of panel thickness for five different construction materials are shown.
