I started hearing a similar sound recently. I don't know if the fact that I had been sitting in a loud open office layout for a year or two was related, or a coincidence. Like others here, I listened to a lot of loud music over the years, mostly using earbuds and headphones, with a few live shows. Also like others here, I've found the usual combination of (lack of) exercise/sleep/stress are factors, and I suspect age contributes as well.
