Waves inhibitors

  1. Mar 9, 2015 #1

    sound waves are mechanical waves

    I heard that it is possible, by sending a properly opposite wave, to diminish a sound wave

    is this possible?

    does this apply also to heat waves?

    Yes, you are referring to destructive interference. It does apply to heat waves (electromagnetic waves in the IR part of the spectrum), but it is much harder to cancel them out due to their much shorter wavelength.
