The future of aircraft with distributed propulsion will largely depend on how their engine noise is perceived by people. Particularly in urban areas, public acceptance may depend on how loud or ...

The Lag Series acoustical pipe and duct lagging features a loaded vinyl noise barrier combined with a fibrous glass scrim-reinforced aluminum foil facing on one side. This product is suitable for a ...

The SPS model acoustic duct silencers are designed to provide excellent low- and mid-band noise reduction, while the TPM model offers excellent broadband performance at reduced static pressure loss, ...

Flow-induced acoustic resonance in ducted systems is a phenomenon where the interaction between fluid flow and the geometric features of ducts gives rise to self-sustained oscillations of sound. This ...
