1、Noise is included aerodynamic noise and structure noise.
2、The noise at lower part of railway cars consists of rolling noise, aerodynamic noise and driving device noise.
3、The key point of reducing noise of paper machine is to reduce aerodynamic noise of vacuum couch.
4、Described are the sound source detection method for the aerodynamic noise on Shinkansen rolling stock and relevant noise reduction measures.
5、The vibration force acting on the fluid directly comes into being the aerodynamic noise.
6、With the constant increase of the trains' speed, the aerodynamic noise gradually succeeds the traditional track noise and becomes the main noise source of the high-speed trains.
7、Using acoustical holography, some interesting results are shown about the different noises of a high speed vehicle, such as engine noise, tire noise and aerodynamic noise.
8、Study on the aerodynamic noise of a fastback car with rear view mirrors in uniform motion and accelerated motion
