Yes, anti-resonance (aka damping, or spectral zeroes) is defo a thing in acoustics. It can be conceived of as a freq component travelling in the opposite direction from the direction in which the main wave is travelling, thus subtracting from energy in that freq.

@_thegeoff@mastodon.social @gahlord@post.lurk.org PS it's how noise cancellation works: flip the ambient spectrum upside down, thus turning ambient resonances into anti-resonances, then add that to the desired signal + ambient mix, and thus effectively subtract out the ambient noise
