噪声是一种影响人类环境与健康的污染源。长期以来人们与噪声做了不懈的斗争。随着现代科学技术的不断进步和发展,人们又研究和发明了许许多多消除噪声的新技术。 由英国科学家研制成功的新型消音系统由一组声音探测器、信息处理器和声音合成器组成。当声音探测器“听到”噪音时会把这些噪音的强弱、方向等数据传输给信息处理器.信息处理器分析后,指令声音合成器发出与噪音波振动方向相反的声音信号,这样噪音即可消失。如果将该系统摆设在床头、沙发、办公桌等周围,还可以在小范围内取得“闹中求静”的效果。科学家说,这种消音系统可广泛应用于飞机、汽车、宾馆等。
Noise is a source of pollution that affects human environment and health. For a long time people made unremitting struggles with noise. With the continuous improvement and development of modern science and technology, many new technologies have been researched and invented to eliminate noise. The new muffler system, developed by British scientists, consists of a suite of sound detectors, information processors and sound synthesizers. When the sound detector “hears” the noise, it sends the data such as the strength and direction of the noise to the information processor, which, after analysis by the information processor, instructs the sound synthesizer to emit a sound signal in the opposite direction to that of the sound wave so that the noise Can disappear. If the system is placed in the bedside, sofa, desk, etc. around, but also in small areas to obtain “quiet downtown” effect. Scientists said that this muffler system can be widely used in aircraft, cars, hotels and so on.
