Noise Levels of Vibration Machines
Noise Levels of Vibration Machines. The noise made by a vibration machine needs to be minimum for many reasons. (a) Who wants to hear a motor roaring near the ears all the time while exercising? It is terribly uncomfortable. (b) Often, the noise comes because of the walking machine phenomenon, in which the machine moves around the room while one takes exercises on it. (c) Also, even if the ...

Vibratory Feeder Noise Reduction
machine cycle rates increase, vibration increases, and there is a corresponding increase in noise levels. Vibratory feeders are not immune to this exponential rise in speed requirements. As one of the fundamental building blocks of automated assembly systems, ever-larger feeders are being pressed to run ever faster to keep up with ever increasing production rates. Additionally, as the use of ...

12. VIBRATION ISOLATION
High vibration levels can cause machinery failure, as well as objectionable noise levels. A common source of objectionable noise in buildings is the vibration of machines that are mounted on floors or walls. Obviously, the best place to mount a vibrating machine is on the ground floor. Unfortunately (but fortunately for noise control consultants), this is not always possible. A typical problem ...
