Reducing Radiating Area

Generally speaking, the larger the vibrating part or surface, the greater the noise output. The rule of thumb for quiet machine design is to minimize the effective radiating surface areas of the parts without impairing their operation or structural strength. This design includes making parts smaller, removing excess material, or cutting openings, slots, or perforations in the parts. For example, replacing a large, vibrating sheet-metal safety guard on a machine with a guard made of wire mesh or metal webbing might substantially reduce noise because of the reduced surface area of the part (see Figure 6.6.6).
