Measurements in numerous peanut shelling plants revealed that the striking of metal surfaces by peanut pods and kernels was a major source of noise. Noise level was affected by thickness of metal and kinetic energy of peanuts (height of fall and flow rate of peanuts). Results from controlled tests showed that plant noise could be substantially reduced by use of modified handling techniques, by use of various damping treatments, and/or by enclosure of the noise sources.
