Blame it on Evolution!

If you can’t concentrate due to the irritating beeping sounds coming from that truck backing up, blame the brain confusion on an evolutionary glitch.Natural soumds are created from a transfer of energy (say, a stick hitting a drum) and gradually dissipate ,and our perceptual system has evolved to use that decay of sound to figure out what made it and where it came from.But beeps don’t typically change or fade away over time,so our brains have trouble keeping up —–BY Natalie Wolchover From Life’s Little Mysteries
