声音可以在空气中传播,早在公元前就被人们认识了。但海洋中有没有声音,很长时间人们都弄不清。不少人认为水下是无声的世界,鱼是哑的。但是渔民们很早就知道,如果把耳朵贴在船板上,就可以听到水下鱼的叫声。 海洋声学作为近代科学,一般认为是从1826年在日内瓦湖测量出水中的声速开始,当时用的方法很简单。对海洋声应用的第一次大的推动是“冰海沉船”。面对豪华客轮泰坦尼克号触冰山而沉没,科学家提出用声学方法探测水下的冰山。不过最大的推动还是第一次世
Sound can spread in the air, as early as BC people have been recognized. But there is no sound in the ocean, people are confused for a long time. Many people think underwater is a silent world, the fish are dumb. But fishermen have long known that if you put your ear on the ship’s deck, you can hear the underwater fish’s cries. As a modern science, marine acoustics was generally considered to have started with the measurement of sound velocity in the lake of Lake Geneva in 1826, when the method used was very simple. The first major boost to the application of ocean sound is the “ice-sea sunken ship.” The face of the luxury liner Titanic touch the iceberg and sink, scientists proposed the use of acoustic detection of underwater icebergs. However, the greatest impetus is the first world
