You can get tinnitus maskers to use at night if tinnitus disturbs sleep. Mine is a little battery powered machine (sold as a travel version) that looks like a 1970s transistor radio & sits by the bed. I think mine came from Action on Hearing Loss - still seems to be available on their website.
It has lots of different sound tracks to choose from so you can match to your own pitch/pattern of tinnitus, which then fades from consciousness - falling rain, surf sounds, wind chimes, steam train
etc. Volume is adjustable so you can turn right up in the middle of the night to wake your snoring partner. Alternatively pick it up & chuck it at him. Win win!
The sound quality is better - less tinny - if you hitch it up to a little speaker - a PC speaker will do. You can set it to play constantly throughout the night or switch off after a set period if you just need it to get to sleep. There are some that can be used under the pillow if sleeping partners are disturbed by the noise - assuming you don't want them to be!
After 7 years of very intrusive tinnitus with a horrible wavering tone, over the last 18 months mine has quietened considerably & the tone is now even, so most days it's now no more than a quiet background hum & much easier to tolerate. So please don't give up hope & assume you will be stuck with a distressing degree of it for life.
The masker is still useful to drown out OH's snoring!
