60秒科学:Weak Have Stronger Hearing

If you ever got picked on in the schoolyard, you might have wished for some sort of superpower: like unbeatable speed or maybe just the ability to completely disappear. Now scientists at the College of Wooster in Ohio say that you might have had a skill you didn’t realize: the uncanny ability to hear a bully¹ coming.

An earlier study found that women hear approaching noises sooner than their bigger, brawnier male counterparts. Perhaps, the scientists thought, the same would hold true for scrawny specimens² versus³ the truly buff. So they had 50 volunteers listen to a tone that sounds like it’s moving toward them. The listeners pressed a button when it sounded like the tone arrived. The scientists then assessed each subject’s strength and cardiovascular fitness.

And they found that the 98-pound weaklings banged their buttons quicker than the well-muscled, because they perceived the threatening sound as being closer than it actually was. The finding got a hearing May 21st at the meeting of the Acoustical⁴ Society of America in Portland, Oregon.

Such auditory overreacting, the scientists say, could be a survival mechanism⁵. So that the meek⁶, while waiting to inherit the earth, can avoid getting knocked onto it.
