Measuring and Simulating Acoustic Absorption of Open-Celled Metals

Aircraft noise is of great importance for aircraft passengers and residents near airports. Excellent candidates as metal fiber felts or metal foams to absorb engine noise are experimentally investigated in acoustic absorption measurements.

Zusammenfassung:Aircraft noise is of great importance for aircraft passengers and residents near airports. Excellent candidates as metal fiber felts or metal foams to absorb engine noise are experimentally investigated in acoustic absorption measurements. Additionally, the empirical Delany–Bazley model is applied to receive simulation results. The comparison of measured and simulated results shows good agreement.
