Laboratory Investigation of Noise-Canceling Headphones Utilizing "Mr. Blockhead"
Physics Teacher, v51 n6 p332-333 Sep 2013
While I was co-teaching an introductory course in musical acoustics a few years ago, our class investigated several pieces of equipment designed for audio purposes. One piece of such equipment was a pair of noise-canceling headphones. Our students were curious as to how these devices were in eliminating background noise and whether they indeed block low-frequency sounds as advertised.
