Reduction of Acoustic Responses using Viscoelastic Damping Materials
Item
- Title
- Reduction of Acoustic Responses using Viscoelastic Damping Materials
- Description
- This paper presents the results of a development test conducted at GE/ASD for reduction of acoustic responses of honeycomb panels using viscoelastic damping material. The damping strip consists of viscoelastic damping material, honeycomb core, and graphite constraint layer. Acoustic tests were conducted on the undamped and damped panels. The comparison of the acoustic responses with and without damping strip are presented. Analytical prediction of the reduction factors and their comparison with the test results are also described.
