Basic study on active acoustic shielding (Improving noise-reducing performance in low-frequency range)

Active acoustic shielding (AAS) is a system that can attenuate a sound passing through an open window. An AAS is constructed from a number of AAS cells set in an array having an approximately co-located microphone and speaker system. The concept of AAS was previously demonstrated and some simple sim...
