If you didn’t already know, Honda makes a lot of other things besides just cars, including a jet, generators, a robotic lawn mower and ASIMO. The company’s latest creation is this, the Sound Sitter, which is meant to calm down babies when they expressed discomfort.

According to Honda, the Sound Sitter is a stuffed toy in the shape of classic S600, and carries a built-in speaker that is linked to a smartphone. The idea here is to identify “sedative” sounds with the frequency characteristic closest to what a baby would hear when he/she is still in the womb.

To do so, Honda recorded the exhaust notes of 37 cars it has made in the past. These include the 2002 NSX Type R, 1966 S800, 1992 CR-X del Sol, 1978 Prelude, 1999 S2000, 1987 Civic and 1999 Insight, among many others.

In a highly scientific test, 12 babies were introduced to the Sound Sitter for two minutes the moment each began crying, with their heartbeat and respiratory patterns monitored. Out of all the engine sounds played, 11 out of 12 babies were soothed by the sound of the 2018 NSX and its 3.5 litre twin-turbo V6.

Of course, because there is science involved, Honda says that the glorious noise made by the NSX is not expected to be of much help when the child is hungry or has a full diaper. Nonetheless, if you want to calm your child down when the express discomfort, play them a sound clip of a NSX revving.
