Completely cancels the energy of that frequency.
Very effective. You will NOT hear any vehicles approaching you. Those pesky sirens you'd hear when the fire trucks are bearing down on you to save your home burning to the ground won't interrupt the reveries of sweet, sweet music.
I am sure y'all gather I am not a fan of blocking the hearing in this way. Attenuation, not cancellation, is what we want. Not being able to hear emergency vehicles or other important ambient sounds, not good.
Noise cancelling is not legal, but soft earplugs are OK in CA now, though. I've never had any problem hearing emergency vehicles with these in my ears.
