 　　If you've ever tried out a flirt¹ up at a party or a club or maybe a construction side, you'll know it can be tough making yourself heard above the din². One solution is to go home and text your love interest. But a more immediate³ one, is to shout. And that is pretty much the approach of male grasshoppers⁴ take when the roar of traffic treantens to drown out their mating calls. The results appear in the British ecological⁵ Society Journal Funtional Ecology. Lots of animals use sounds to woo a potential partner. But what happens when an unnaturally⁶ noise environment all but overwhelms such romantic intridies. To see how grasshoppers cope with vehicular clamor, researchers collect about 200 males half from the stripe along the highway. Then they showed the lads a female and recorded the results. It turns out that compare to males lives some place quiet, the roadside chripers selectively boosted the bass⁷ notes in their love song, percisely the part that would have gotten lost during rush hour.
