I am it sure anyone is interested in this article which ended up in my inbox today. Myself I found it interesting so decided to share it.

Actively reducing noise by ionizing air

EPFL scientists show that a thin layer of plasma, created by ionizing air, could be promising as an active sound absorber, with applications in noise control and room acoustics.

Thanks for sharing! This is a very interesting possibility: install plasmaionizing panels to act as active room tuners to tune/cancel out room modes. Now just got to deal with the ozone generated by them....
