My tinnitus is 24x7, pure tone. When it started, I can’t recall, but for as long as I remember, it’s been an ongoing thing. The tone is at 4kHz without fail all of the time, although every so often, there are a few variances that occur, up or down in frequency. As to volume, that I couldn’t say, but I would say it is similar to the average volume of a conversation.
As others have asked/postulated, with tinnitus affecting a hearing test, for myself, yes. Hearing tests for me are difficult unless there is a warble or beep rather than a steady tone. From my posted audiogram from 2018 which was done with a steady tone, this past year with the warble/beeps used for the hearing test, I believe I was told I had a 5db improvement in hearing from 4kHz-8kHz. Not so much an ‘improvement’ but that I was able to better recognize that the tone was there rather than a phantom tone from my tinnitus.
