2007 Porsche Cayman — buzzing noise only at one engine RPM

There is a light buzz from the dash at one narrow RPM range. It disappears above and below that speed. Any good method for locating trim resonance without randomly adding foam everywhere?

Thanks — that narrowed it. I'm going to try the simpler check on the 2007 Porsche Cayman first. I'd rather look cautious in this thread than stuck later.

I'd keep this practical. Verify the cheap/easy branch on the 2007 Porsche Cayman before a big repair or a big spend. I'd do that before spending real money. Have you gotten a second quote in writing? Your commute and mine probably aren't the same, but the test still applies. This is me being the wet blanket on purpose.

I parked the 2007 Porsche Cayman and wrote down what I already tested so I'm not repeating myself. Might be overthinking it, but I'd rather overthink than overspend.

Don't overfit one forum story to your car. If it still isn't clear on the 2007 Porsche Cayman, a specialist hour can be cheaper than another round of parts. Then you'll know the next fork. No need to make it theatrical. If the story changes I'll post the new data.
