When I run the Waveguide Simulator demo on my Alienware M15 Ryzen Ed. R5 (has a RTX 3070; Windows 11 Pro, Chrome v129), I hear a distinct high pitched flutter noise emanating from my laptop. I thought it was from the speakers, but no, with my volume down it was still present as long as the simulator was playing. Weird, but very cool demo (probably my hardware, never hear this during games or other WebGPU demos). The realistic house simulation yields a different signature in the sound.

Coil whine (or capacitor whine) from the gpu running at too high a refresh rate. Easiest thing would be to use nvidia control panel to add an fps cap to something like 2x your monitors max rate for the browser (or globally). It's pretty common with any workload after like 600 fps.
