I have somato-sensory tinnitus that was caused by a neck injury. Yoga and related flexibility training are the only things that have ever helped. I think it is because they simultaneously correct and strengthen my neck posture while calming my sympathetic nervous system. This treatment the article describes seems to be doing the same thing — using multiple sensory inputs to alter how the nervous system self regulates.
I miss that too, but sadly there is no easy equivalent. You just have to make local DNS your friend. I’m in the process of going ipv6-only on my home LAN (because I’m a tech nerd). I enable avahi/bonjour on everything that supports it, then I simply connect to <hostname>.local.
Any servers that require a static v6 IP address get something like <prefix>::BABE:CAFE:1 mostly just as a way to remind myself that the address is static and not allocated by SLAAC.
