There’s an old trick for getting babies to sleep:  Just drive them around in the car for a while.  But now you might not have to waste all that gas . . .

Scientists in the U.K. worked with a music producer named Tom Middleton and created a bunch of music that SIMULATES the driving sounds that put kids to sleep.

Apparently the vibration of the road does help.  But the hum of the ENGINE also plays a big part.  The music doesn’t sound like a car engine though.

They used a bunch of car sounds . . . like the engine hum and the air conditioner.  But they mixed it with ambient music, and a combination of, quote, “white, pink, and brown noise” in various tones.  So the car sounds are really subtle.

They ended up with 15 minutes of calming music that supposedly puts kids to sleep, just like driving does.

The whole thing is part of a promo for the Nissan LEAF . . . their fully electric car that doesn’t make any engine noise.  You can listen to the full 15-minute song on Spotify.  Just search for “Tom Middleton Dream Drive“.
