Something else that could be done is to try and make an sorta sound absorbing box or area around your setup like some people do for microphones.
Additionally you can also put up stuff on your walls that absorb sound too, foam is generally the best but also expensive obviously as all sound enthusiast want or use it. But just by putting up something not flat against the wall helps especially if it’s triangle shaped since then it can capture/entrap sound diffusing it at the least which compared to a flat surface that will just bounce the sound around helps a bit.
Something I’ve done myself for an large room I have my computer in is segregate an alcove area off via getting an extendable curtain rail and put on some black out curtains which results in the sound struggling to escape from it since it bounces off the curtains if it even escapes from the dips in it.
