Measurement of Vibroacoustic Performance of Close-Fitting Honeycomb Sandwich Structures
This paper considers acoustic treatment of honeycomb sandwich panels in close-fitting enclosures. Honeycomb sandwich panels are efficient radiators of sound because they are generally optimized for high stiffness and low weight. Results confirm that adding absorption at the mass-spring-mass resonance of a honeycomb panel with a thin plate has practical benefit. The absorption minimizes the effect of the ‘mass-air-mass’ resonance which usually reduces the low-frequency transmission loss, and offers increased performance at higher frequencies. The potential of composite honeycomb sandwich panels for reducing noise below 500 Hz is also demonstrated.
