<正>It is well known that animals are affected by human noise pollution.For example,dark-eyed junco birds that live in cities sing both louder and with a different song than their countryside counterparts.However,human noise pollution is not contained to cities,and even our oceans are filled with the noise from ships,motorboats and jet skis.Most research into human noise pollution has looked at how animals deal with communicating when there's more noise than what they're used to.
