All the best for our recovery!
Having recently suffered a minor stroke, I know what it is to lie around in hospitals... a good cure during rehab was seeing all those other patients who had been hit far harder than me.
From day one, I had my pocket trumpet with me to practise; unfortunately without a mute. I then ordered Thomann's own brand warm-up mute which did the job. Nice, small, and well intonated, it surprised me as being better than the Wick... can only recommend it.
As to sound reduction: Quite a few nurses encouraged me to play, seeing my horn. And were very astonished when I told them that I was working on Arban up to two hours per day. No one outside my room had noticed...
