噪声能干扰人们的工作、生活和健康,因此人们对控制和消除噪声的呼声日益强烈。将噪声降低到无害的程度,已经成为国内外一项重要的研究课题。发动机减噪美国希格比教授利用反噪声技术,成功地减小了大柴油机的低频振动。其原理是用一组传感器将检测到的柴油机信号输入计算机,然 Noise can interfere with people’s work, life and health, so people’s voices to control and eliminate noise are increasingly strong. Reducing noise to harmless levels has become an important research topic at home and abroad. Engine Noise Reduction Professor Siegbi used the anti-noise technology to successfully reduce the low-frequency vibration of a large diesel engine. The principle is to use a set of sensors to detect the diesel engine input signal to the computer, however
