I've had tinnitus for years. Annoying noise, 24x7, it never stops. Today my wife and I are watching TV and I heard a sound, or odd and sudden lack of a sound. I asked her to pause the TV. Sure enough the endless noise in my ears was not there. Decades, simply decades of noise.
I got new hearing aids two weeks ago. Some say hearing full spectrum sound can mitigate tinnitus effects. Seems like it did.
