Why a quack beats a honk behind the wheel

A quacking car horn works better than the traditional honking noise because it is less stressful, researchers say.

Sound experts developed the device that sounds like a synthesised duck after different sound variations were tested on 100 volunteers.

Professor Myung-jin Bae, the lead researcher from Soongsil University in Seoul, South Korea, said: “Our new klaxon sound can immediately alert the pedestrians of the danger while also reducing the unpleasantness and stress of the sound.”
