Screech tone
WebIt is known that the screech tone is generated by the interaction of the unsteady jet shear layer of high-speed flow and the train of shock cells in the jet, where the instability wave propagates downstream and is amplified by the feedback mechanism of the acoustic wave propagating upstream [ 1] [ 2 ]. WebA screech tone frequency prediction formula is thus proposed based on this relation. The predicted screech wavelengths or Strouhal numbers of cold and hot jets all agree well with the experimental data by other researchers, except for a small discrepancy for the B mode.

MY headphones (Razer Carcharias) emit a high-pitched coil whine into my ears. It's quite subtle on the desktop, but as soon as I put my PC into load like when I launch a game, it becomes a squeal and is incessant and awful.
