Noise regulations in a key Latin American country were revised to a lower level, forcing CNH and other construction equipment manufacturers to reduce the noise footprint of their products.

Results Validation:

“Simulating the acoustic performance of alternative approaches to noise remediation helped us meet the tighter noise specification in about three months,” Tamamidis said. “If we had to rely on physical testing for this project, it would have taken at least a year to reduce noise to the levels needed to meet the new spec. Due to successful projects such as this, we have integrated Actran into our product development process and use it on a regular basis to help ensure the acoustic performance of new designs and solve problems with existing designs.”

  • Quicker understanding of noise contributors
  • Simulations proved more comprehensive than physical test
  • Met noise specifications faster
  • Able to ensure acoustic performance of new designs
