The Noise-Canceling Handset uses a sophisticated microphone to filter out background noise.  It also filters out feedback commonly heard from paging systems. Unlike standard microphones which only have ports in the front, noise-canceling microphones have ports in the front and the rear. Since ambient noise enters the microphone from both ports, the same pressure is put on both sides of the diaphragm. Because the ambient noise doesn't make the diaphragm vibrate, the ambient noise isn't heard.  Since speech is entering from only the front of the microphone, the diaphragm vibrates from only the speech which means the background noise isn't heard. With a noise canceling handset, the caller must speak directly into the microphone.
