I struggle with tinnitus distress and Ménière's. One of my coping strategies is to continuously play some sort of background sound in the areas I occupy.
I have a first gen RPi with a set of USB powered speakers in my bedroom that plays long form background soundscapes I get from YouTube on loop. This is the lowest tech I could muster. YouTube-DL is a command line tool that fetches content from places like YouTube and recodes it. I use mpg123 to play the resulting audio file on loop... and because I'm already using ssh for all sorts of other things as go about my day this workflow is basically completely integrated into my normal day-to-day activities.
When I first started doing this I changed the audio track on a fairly regular basis. Sometime to suit my mood, other times for the weather. These days it's more of a seasonal thing.
It works great. It's proven to be really reliable and it was really, really cheap.
