I bet you could remove it fairly easily. Use another laser to count the revs or something. Your brain does most of the work in removing noise from speech.

- enneff 13y agoOr just use two microphones—one aimed at the windshield and one at the bonnet—and subtract one from the other.
- RBerenguel 13y agoThen it turns into a significantly more complex problem. The thing with removing noise from speech is that the amount of vibration from the glass due to speech is negligible compared to the vibration due to the motor
- hamiltonkibbe 13y agoI don't think it's that straightforward, a few feet of difference in source position amounts to a phase shift of significant percentage of a wavelength at audio frequencies. You can't just flip phase and sum. It was also my understanding that laser microphones require very precise alignment, and getting one lined up normal to a convex, moving windshield is at least a tiny bit more than "trivial"
