Not necessarily for sound, on industrial fans and drives, we can program in skip frequencies to avoid any resonance issues in the system. I've never done it for noise reduction. But I do some tweaks for efficiency and power consumption reduction. There's some wild industrial design stuff out there, and in the end, it's because it provides something the customer wants. I won't go into specifics, but you can design the same components the same for multiple manufacturers and do some slightly different things in its construction to give the vibe the OEM wants, or to fix some inherent characteristics in the manufacturers platform. It's REALLY cool when you think about it. Sorry to be so vague, but I have to be.
