    Sound dampening material inside the ear protectors filters and cancels sound waves. This uses the physics of attenuation to reduce sound energy.

    Back in my aerospace engineering days, I used to design noise suppression panels and turning vanes for post-overhaul jet engine test facilities (somewhat little larger than ear plug or muffs).
