This video suggests that sound cancellation is possible with just a microphone, amplifier and surface transducer but doesn't explain how the sound being produced by the speaker/transducer is ensured to be 180° out-of-phase with the sound going through the panels. Is it the spacing between the microphone and the speaker or is something else needed?
