Abstract
A noise attenuating system includes a core portion adapted to actively filter sound waves into various bands, passing only those bands corresponding to safe amplitude sounds to a wearer's ear canal. Unlike conventional active noise cancellation systems, active noise attenuation is accomplished without providing additional sound waves inverse to unsafe amplitude sound waves. Instead, unsafe amplitude sound waves are passively blocked, and only safe amplitude sound waves are passed through to the wearer's ear canal.
