Making engine sounds pleasant

Sound Design Lab LLC and the Takeshi Toi Laboratory at Chuo University in Japan have been working on a project to make engine sounds more pleasant to listen to. The idea is that engine sounds are usually perceived to be noise pollution, however the researchers have discovered that engine sounds are quite similar to stringed instruments.

Some people are concerned that the noiselessness of electric cars can make them dangerous, especially to pedestrians. The team is investigating sounds that they can use that will sound enough like an engine to give people cues on how fast the car is going, and from what direction, but at the same time sound nice.
