HOW IS NOISE MADE?
Sound can be produced by vibration or as a result of aerodynamic systems. Vibration-induced noises are produced by:- Mechanical shocks and friction between parts (e.g., hammering, pressing, running gears, bearings, cutting tools, chutes, hoppers, etc.)
- Out of balance moving parts (e.g., unbalanced rigid rotors)
- Vibration of large structures (e.g., ventilation ducts, guards on machines, equipment supporting structures, etc.)
