    Vibration of large structures (e.g., ventilation ducts, guards on machines, equipment supporting structures, etc.) The sound may be amplified by reflective surfaces that are around the devices. Aerodynamic sources of noise are air or fluid flows through pipes and fans, or as the pressure drops in the air distribution system.

  • Vibrating Screen Working Principle

    A vibrating mechanism attached to the middle of the screen imparts rapid vibrations of small amplitude to its surface, making the ore, which enters at the top, pass down it in an even mobile stream. The spring-loaded bolts, which can be seen in section in Fig. 7, move with a hinge action, allowing unrestricted movement of the entire screening10 ENGINEERING NOISE CONTROL WHO,ENGINEERING NOISE CONTROL strongly suggests that when control takes the form of understanding the noise-producing mechanism and changing it to produce a quieter process, as opposed to the use of a barrier for Often noise sources are either vibrating surfaces or unsteady fluid flow (air, gas or steam).
