摘要

<正> Some scientists say that animals in the ocean are increasinglythreatened by noise pollution caused by humans.The issue of noisepollution in the oceans was dissussed at a conference this month ofthe Acoustical Society of America.The noise that affects sea creatuescomes from a number of human activities.It is caused mainly byindustrial under-water explosions,ocean drilling,ship engines andsubmarines.Such noises are addded to natural sounds.These soundsinclude the breaking of ice-fields,under-water earthquakes andvolcanoes,storms and sounds made by animals themselves.
