9-years between the start and complete deafness. I didn't see a Dr for the tinnitus alone as it wasn't that bad. About 8yrs later, my ear started feeling stuffed quite frequently, but I could still hear okay. Around year 9, one night I woke up with a vertigo attack so bad, couldn't hardly walk and the slightest bit of head movement made me nauseous. I realized at that time, the vertigo took my hearing with it, replacing it with much louder tinnitus that sounds like cicadas in August. Vertigo attacks were on and off for a week before I went to see the Dr. Was told it was Meniere's. Then the vertigo passed, but my hearing stayed gone.
