That sounds very technical and complicated for many stoners to grasp onto right away! :stoned:

But, if you can manage to get it to work, then you'll be heralded as a pioneer, and will have many follow in your footsteps. So if you have the means to try an experiment like this, then by all means, please do! And report back to us when you've gathered your results.

Take care. :jointsmile:
Mr. Clandestine Reviewed by Mr. Clandestine on . Active vs passive noise control (of fan noise). Sound insulation (a massive barrier which blocks sound transmission) or sound absorption (a porous material that "sponges-up" sound) are passive noise controls (sometimes called "soundproofing"). Active noise control (noise cancellation or anti-noise) uses a speaker (either near the noise source or near the person's ear) emiting sound of the same amplitude, but with the opposite phase (polarity) of the noise. The two sound waves "cancel" each other out, thus reducing the noise Rating: 5
