HTG 419: Plasma-Based Sound Absorption - A new method of acoustic treatment

Acoustically treating a room normally involves bulky panels and other passive materials that must be very large and thick to affect low frequencies. But a new technology could do away with all that, replacing it with super-thin panels that use ionized air to perfectly tame the acoustics of any room.
