This historic Ig Nobel Favorite Moment video stars Kazutaka Kurihara and Koji Tsukada, who were awarded an Ig Nobel Prize in acoustics, for creating the SpeechJammer — a machine that disrupts a person’s speech, by making them hear their own spoken words at a very slight delay.
The Ig Nobel Prizes honor achievements that make people LAUGH, then THINK.
The 30th First Annual Ig Nobel Prize Ceremony will be webcast September 17, 2020 at www.improbable.com.
