This example problem uses acoustic elements and viscothermal losses (comparing a boundary layer impedance [BLI] model and a low reduced frequency [LRF] model) to analyze the noise-reduction of sound-absorbing trim panels with quarter-wave resonators.
The following features and capabilities are highlighted:
The following topics are available:
You can also perform this example analysis entirely in the Ansys Mechanical Application. For more information, see Acoustic Analysis of a Viscothermal Resonator in the Mechanical Technology Showcase: Example Problems.
