What do you guys do when masking doesn't help your T? Mine is so loud and high-pitched in one ear that I can't cover it with white-noise when I try to sleep. I'm using a fan, a window A/C unit, and a white noise app on my phone. It does the job ok enough when I'm awake, but as soon as I try to sleep the T is out of control and can't be covered. This is a recent development so hoping it'll level off soon... Thanks in advance.
