Tub Grinder Sound Power Troubleshooting

Industry: Off-Highway

Applications: Troubleshooting

A manufacturer of agricultural, environmental, and construction equipment selected Sound Answers to perform sound power measurements and to teach troubleshooting tasks to identify key components driving sound power results of their tub grinder. Standardized sound power measurements were conducted to quantify source and an assessment of which bands contributed the most to the overall level were focused on. Once focus was narrowed, both acoustical and structural resonances were calculated/measured to determine whether root cause was a forced response or modal. A root cause was identified and recommendations were accepted which reduced the sound power results of the tub grinder. The techniques used for this project among others were taught so that the customer can later solve similar issues in the future.
