Low Frequency Noise Reduction Using Novel Poro-Elastic Acoustic Metamaterials
Low frequency noise is a common problem in aircraft and launch vehicles. New technologies must be investigated to reduce this noise while contributing minimal weight to the structure. This thesis investigates passive and active control methods to improve low frequency sound absorption and transmissi...
