Advances in Experimental Research on the Influence of Friction Powders on Acoustic Liners (Helmholtz Resonators)

This paper presents the technological advancement of using friction powders to increase the absorption of acoustic liners used in the reduction of tonal noise generated by aero-engines or for other applications related to Helmholtz resonators used in noise absorption of low frequencies. The experime...
