An agricultural equipment manufacturer chose Sound Answers to troubleshoot an acoustic boom and identify possible countermeasures. Static and operating noise and vibration measurements were made applying the source-path-receiver model at the customer’s US facility. Spectral, order, and modal analysis were utilized to understand key components of the acoustic boom. This boom consisted of high source levels coupled with a modal alignment issue that surfaced after a design change was made during the development process of the project. The customer accepted the countermeasures recommended by Sound Answers which consisted of reducing the source level and also shifted the coupled resonances. In addition to recommended changes, Sound Answers has also helped the customer develop a mode alignment chart to use as a reference during future tractor development processes.
