I don't know it this is tinnitus, but lately when I park my car in the basement at the end of the day and sit there for a moment and everything is quiet, I have something like "white noise" which I can hear, and also a constant high-pitched hum. This started recently. (It continues into the evening, but later when I put on the radio I don't notice it anymore.)
I have had problems with hyperacute hearing in the past, but it happens quite seldom now -- I very seldom experience sensory overload. (I wear hearing protection from time to time, though, e.g. at a night club or in an aeroplane or a shopping centre.) But at the time of my big sensory problems, I do not recall having this "white noise" thing. (I'd say one thing, though, I'd rather have the white noise than the hyperacute hearing!)
I was wondering if it could be related to my medication (methylphenidate, lamotrigine), or perhaps to the ambient sound at the office during the day, or just to working too long without a proper break. I only become aware of it in the evening. It does not seem to be there at other times (although during the day there are other sounds, so maybe I just don't notice). it isn't there when I wake up.
Any ideas about why it could be happening at the end of the day?
