| contents | The development of acoustic simulation workflows in the time-domain description is essential for predicting the sound of aeroacoustic or other transient acoustic effects. A common practice for noise mitigation is using absorbers. The modeling of these acoustic absorbers is typically provided in the frequency domain. Several, methods established bridging this gap, investigating methods to model absorber in the time domain. Therefore, this short article, describes the analytic solution in time-domain for benchmarking absorber simulations with infinite 1D, 2D, and 3D domains. Connected to the analytic solution, a Matlab script is provided to easily obtain the reference solution. The reference codes are provided as benchmark solution in the EAA TCCA Benchmarking database as METAMAT 01. |
