I think when my tinnitus is acting up, I don’t hear some high tones as soon as I would otherwise, as they are being masked. So before the test, I don’t drink coffee or do anything else that may increase the noise in my head.
Many years ago, as I walked into the building for my first hearing test, I passed under a ventilation fan that had a bad bearing. The squeal suddenly increased the tinnitus in one ear. Naturally, I scored poorly in the test.
The technician was concerned that I might have a tumor, despite my description of the sudden increase in tinnitus. He insisted on my undergoing an scan on my head, which was negative. Or as my wife teased “They didn’t find anything.”
A re-test the next year was normal, showing mild/moderate loss essentially equal in the two ears (which got much greater 10 years later following chemo).
