Why would rotation speed inversely affect head noise?
- rbinv 6y agoYeah, I came to the same conclusion after thinking about it some more. Looks like a faulty memory.
- sandworm101 6y agoEver drive a manual transmission? At very low RPM the engine will seem to shake more. It isn't so much that there is less vibration at higher speeds but that it occurs at a higher frequency. That means the amount the part physically moves from one side of the oscillation to another is less, just as a higher-revving engine doesn't bounce around as much as it would at lower RPM. The total amount of noise/vibration may be similar but the change in frequency can still have other effects.
