Gear-noise: diagnosis & control

Moin Mujawar CAE analyst

The Course structure was very constructive. Milind Sir has extensive experience in NVH & Acoustics domain. The way he explained NVH and acoustics concepts made even complex topics easy to understand and apply. His practical insights and structured approach added great value to the learning experience. I truly found this course to be highly informative and beneficial, and I would strongly recommend

Quick gripe first: Module 4 on damping theory ran a bit long, and the quiz felt padded. That said, the habit of calling out what actually changes between versions saved time; fewer “is this still true?” pauses. As a freelancer, I liked how it tied NVH choices back to outcomes in prod, not just math. The Chapter 3 example on order tracking—specifically the gear whine FFT waterfall—stuck with me because it mapped cleanly to decisions you’d make in the arch review. Labs didn’t assume much infra, which helped. It closed a gap between what I knew and what I assumed I knew about noise paths.

Quality stayed pretty even across modules, but module 4 dragged a bit and the labs assume you’ve already got MATLAB wired up. After that, it clicked. The “Modal Testing Basics” section with the door panel resonance example at ~180 Hz stuck with me, especially how they tied frequency response back to design tradeoffs. As someone bridging legacy code and newer infra, I kept mapping the NVH flow to how we think about obs in prod: measure first, then tweak arch. The transfer path analysis chapter felt like reading a clean PR—clear inputs, fewer guesses. I’ve already borrowed the checklist style for a CI gate around RPS regressions. Not flashy, but it fits day-to-day work.

Sat through plenty of advanced NVH courses, and this one actually bites. It doesn’t float at slide level; it pushes into how decisions land in prod when targets get ugly, and that kept me engaged between meetings. The bit that stuck was the order-tracking walkthrough in the powertrain chapter, where they map 2nd order boom during a 3,200 RPM coastdown and show how a mount tweak shifts the peak; I’ve already mirrored that flow in my repo for a current PR. There’s practical glue too: tying CAE outputs to test obs, plus a quick nod to how CI can gate NVH regressions before release. I wasn't sold on the intro pacing, and I wished there was more on road-induced NVH at low RPS, but mostly it held up. I've felt the gap close between sim and test, and my day-to-day loop is shorter with fewer re-runs.
