Industrial Noise and Vibration Control The main purpose of industrial noise control is to protect the hearing of the people  working in the production units, factories and workshops etc.  Noise generated by fluctuating forces in structures...The internal forces in a machine are  transferred as structure-borne sound to the surface where it is radiated as sound...The  forces can be either steady, caused by reciprocating motion in an engine, or transient  caused by impacts. ..More noise is produced if a task is carried out with great force for a  short time than with less force for a longer time...Since the structural vibration will have  to radiate as sound from the machine surfaces reduction of the surface area or  reduction of the radiation efficiency of he surface can be good noise control  techniques...An object with a small surface area may vibrate intensely without a great  deal of noise radiation. The higher the frequencies, the smaller the surface must be to  prevent disturbance. Top 10 Noise & Vibration Control Techniques we work on as Consultant. 1.  DAMPING      Typical applications: Chutes, hoppers, machine guards, panels, conveyors, tanks. 2.  FAN INSTALLATIONS      Typical applications: Axial flow or centrifugal fans. 3.  DUCTWORK      Typical applications: Ventilation, cooling, openings in walls and enclosures. 4.  FAN SPEED      Typical applications: Axial or centrifugal flow fans. 5.  VIBRATION ISOLATION PADS      Typical applications: Machine feet, pumps, mezzanine installations. 6.  SOUND ABSORBING MATERIALS      Typical applications: Walls treatment 7.  TRANSMISSION LOSS OR BARRIER MATERIALS      Typical applications: Walls treatment 8.  RESONATOR-TYPE MATERIALS      Typical applications: Noisy rooms treatment. 9.  BARRIERS      Typical applications: free-standing walls or structures to block source noise. 10. ACOUSTICAL BUILDINGS       Typical applications: Customized, highly acoustical enclosures.
