Sometimes the wear plate needs to be drilled. What should we pay attention to during drilling? Here are some information for your reference: choose the correct shape. In order to reduce the volume and noise radiation area of the noise barrier, its shape should be similar to that of the sound source device, And the cover wall should be close to the shell of the sound source device as far as possible, but the requirements of convenient monitoring, good ventilation, normal operation of intake and exhaust and muffler should also be considered
In addition, the surface form should have greater stiffness, which is conducive to sound insulation. The use of square parallel walls should be minimized to prevent the air acoustic effect in the hood
The wall of the sound insulation enclosure shall be provided with enough LTL of transmission loss. The cover material can be lead plate, steel plate, aluminum plate, thin wall and high density plate, generally 2 ~ 3mm steel plate
By strengthening or applying the damping layer, the resonance and coincidence effect of light structure such as steel plate are restrained, and the acoustic radiation is reduced. The thickness of the damping layer should not be less than 2 ~ 4 times of the wall thickness
