• If the ambient noise (an airplane engine, say), is "+1",the 36dB headphones would create and add "-1" so your ear hears 0 (i.e. nothing) better than 95% of the NC headphones, working best with low droning sounds, like car engines, airplane engines, air conditioners, etc. Midrange sounds, like voices, are largely unaffected (though they may sound odd as the low frequency parts of the voices are cancelled out).
