Pre-characterization simulations of geometry. (a) Transmission loss due to cross section changes; highlighted λ/4- and λ/2-resonance frequencies. (b) Overall simulated sound pressure of the MPA setup without MPP compared to single center inlet point at the nozzle (cf. Fig. 6c); indicated cut-off frequencies fc,RFS and fc,MFS.
