The sound of Amazon delivery vans reversing has been compared to a 'demonic crow,' a flock of murderous hawks, and tortoise sex - but the reason behind the bizarre back-up sound could actually be safety, Input reports.
The harsh, grating sound may be intended to be unique and unignorable to prevent pedestrians, cyclists, and other vehicles from tuning out the sound and getting run into by the Amazon vans, author and freelance journalist Chris Stokel-Walker reports.
"I'm in a large apartment complex and kept hearing that," a commenter on a Youtube video of the van said. "It sounded like a crow falling down the stairs and throwing up at the same time."
"I thought one of my chickens was dying! Turns out it was an Amazon truck," another commenter said. Amazon didn't immediately respond to Insider's request for comment about the sound.
"The beep-beeps are annoying, the brain does something called habituation, realizing it's heard the noise several hundred times before," Deborah Withington, a professor at the University of Leeds and founder of Sound Alert Technology, told Input. "You go, 'Oh, for flip's sake, I'm not going to bother responding to that anymore. And of course, it's the one time the vehicle is coming towards you."
