Active high transmission loss panel
First Claim
1. An active high transmission loss panel for use in quieting broadband sound radiation, said panel comprisingpanel means providing passive sound attenuation, said panel means including a plurality of first and second partition or partitioning means, with said panel means defining a number of contiguous cell means and being spaced from each other along the sound radiation path,each first said partition means having a first sensor means thereon and each said corresponding second partition means having a first actuator and second sensor means thereon,said actuator and sensor means, in conjunction with an active noise control means, adapted to attenuate noise impacting on said panel means from passing through to the opposite side.

11. An active high transmission loss panel for use in quieting broadband sound radiation, said panel comprising
panel means providing passive sound attenuation and comprising a multiplicity of first and second spaced partition means which define a corresponding number of contiguous cell means, each said first partition means having a first sensor means thereon and each said corresponding second partition means having a first actuator means thereon and a second sensor means thereon, said first sensor means being spaced from said second sensor means, said actuator and sensor means, in conjunction with an active noise control means, adapted to attenuate noise impacting on said panel means from passing through from one side to the opposite side.
