日本工程师研究的“白”噪音技术,在不久的将来能够让日本生产的小汽车变成世界上最安静的小汽车之一。在尼桑、蓝鸟轿车上使用结果表明,这项技术可以将发动机的噪音量降低10多个分贝。 “白”噪音的原理是通过产生相反的声波来消除噪音。由于研究出功率较大的微机系统,因此这一新技术已经广泛应用于冰箱、飞机和音乐厅上面。尼桑汽车制造厂的工程师们为汽车设计了一套新装置,他们在汽车顶上安装了由4个走克风组成 The “white” noise technology studied by Japanese engineers will in the near future turn Japanese-made cars into one of the quietest cars in the world. The results of the Nissan and Bluebird sedans show that this technology can reduce the engine noise by more than 10 dB. The principle of “white” noise is to eliminate noise by producing opposite sound waves. Due to the development of more powerful computer systems, this new technology has been widely used in refrigerators, airplanes and concert halls. Engineers at Nissan Motor Manufacturing have designed a new set of equipment for the car, which is installed on the roof of the car consisting of four walking winds
