In his annual article in Radio-Electronics
, Mohammed Ulysses Fips described his recent invention of a "Snorekill" snore elimination device. It was an adaptation of his Noise Neutralizer (described in his 1952 column
) adapted for the specific purpose of suppressing snore sounds. It worked by picking up the snoring sounds with a microphone, then reversing the phase of the sounds, and feeding them back into the room, thereby canceling out the sound of the snoring.
