I have the same; it's the bane of my life. It started around 4 years ago, I think connected to a lot of drilling I did in a house with fantastically hard bricks. My hearing is fine but I have to listen to the sound of rain on Alexa to get to sleep as it helps focuses my mind away from the tinnitus.I have constant ringing in my ears exactly the same as after you've been to a loud concert. Although I've seen loads of live music over the years, it isn't to blame. My tinnitus started as a result of a virus about 15 years ago.
The saddest thing is not being able to just sit in the garden, say, and listen to the breeze and the birdsong. The tinnitus ruins it.
