i'm not really sure what a "sound wall" is exactly. but the mining operators like to spit out that phrase as though it's the solution to the noise problem when i'm not really sure how effective those things are.

They are somewhat effective, if you have ever lived next to a highway you would be able to tell. Cheesy

Obviously, they won't make those massive farms 100% silent, from personal experience, I was able to hear "very slightly" the noise from my farm from a 2 km distance, it was on a quiet winter night, obviously, if you don't know where the sound is coming from, at that distance it would just sound like a truck engine somewhere a bit far, but once your ears grasp what miners noise actually is, you will be able to tell, the whistling sound that miners make due to heatsink design and high RPMs is exceptional.

Many people underestimate the noise level that miners make, but in a farm where we had no more than 200 something miners, right on the exhaust side, it was as loud as 120-130db, which is as loud as a jet, powerful it could break your ear drum if you stay there for too long without wearing ears protection.

One thing that would bring the noise level down close to silent for those who live like 1000 meters away would be to get the fans to spin below 3000RPM, that's when they get very quiet, if they spin anywhere near 7000RPM no sound barrier on planet earth would stop the noise from traveling a few kilometers away.

yeah there is some you can do. but if you are sticking with stock 7000 rpm fans that come with the s21 they are noisy . and you need more space to lower sounds .

you can not restrict the airflow too much or you won’t cool the gear.

you also need to be willing to lose hash rate if you aircool in the summer and the temps are over 35c or 93 f

hot weather hurts air cooling a lot.
