Evaluation of a Microporous Acoustic Liner Using Advanced Noise Control Fan Engine

A novel microstructurally controlled graded micro-porous material was developed and experimentally validated for noise reduction through a normal incidence impedance test. Extensive parametric studies were conducted to understand the influence of test specimen size, particle size, porosity, pore siz...
