I can cause tinnitus by pinching my nose, closing my throat, and manipulating my throat to pressurize my skull.. like one does to "pop their ears" after changing altitudes to hear/speak properly again. If my ears start ringing like I feel tinnitus has arrived, I've found it goes away by cycling this pressure a couple times. YMMV
