I agree, I am afraid it's tinnitus, I am a sufferer and a family doctor. I also agree with much of the above comments, in particular that tiredness and stress will aggravate it, not normally caffeine and aspirin, though tinnitus is a symptom of overdoing aspirin. It is usually a corollary of aged related hearing loss, presbycusis. That in turn is related to hair cell degeneration in the cochlea. It's getting older dude. Ironical, as we become old enough to afford High end systems, we lose the ability to appreciate them.
There is little treatment I am afraid, their are rarer causes and if one sided, perhaps with deafness, it needs invetigation. Seek confirmation from an ENT specialist, but there is little treatment and less that works.
It is often the result of earlier noise exposure and I tell my kids, if you leave a gig with tinnitus, you have permanently degraded your hearing, It all adds up. If you have tinnitus, you are very vulnerable to further acoustic damage, so don't go to noisy gigs yourself or play your system at 105db's
