====Buzzing====
An intermediate frequency oscillation in chamber pressure between 200 and 1000 [[Hertz]]. Usually caused due to insufficient pressure drop across the injectors.<ref name=sutton1975/>{{rp|261}} It generally is mostly annoying, rather than being damaging.

Buzzing is known to have adverse effects on engine performance and reliability, primarily as it causes [[material fatigue]].<ref name="HuzelAndHuang" />{{rp|147}} In extreme cases combustion can end up being forced backwards through the injectors – this can cause explosions with monopropellants.{{citation needed|date=April 2018}} Buzzing may cause Screeching.<ref name="sutton1975" />{{rp|261}}
