Comparative Analysis of the Acoustic Characteristics of Composite and Metal Panels Under Sound and Pseudosound Excitation

The results of experimental studies to determine the acoustic and vibroacoustic characteristics of a panel made of a polymer composite material are presented in comparison with the characteristics of a reinforced metal panel of comparable mass and relative stiffness. A comparative analysis of the characteristics was carried out for an unlined panel and a panel lined with a vibration-absorbing material in the case of their excitation by sound and pseudosound fields of pressure fluctuations.
