Wound Therapy Device Sound and Vibration Testing

Industry: Medical

Applications: Troubleshooting

A medical devices company requested Sound Answers to evaluate NVH performance of a wound therapy device focusing on understanding the NVH mechanism of the device and identifying best guidelines for reducing noise and vibration. Operating noise and vibration measurements were conducted within a full-anechoic chamber. The source-path-receiver approach was utilized concentrating on FFT and order analysis to root cause noise and vibration mechanism of the device. Countermeasures to reduce noise and vibration were made from both the source and path side that were effective. However, only path side countermeasures were used due to the wound therapy device being so far along in the development process.
