Antminer S19 silencing

Hey guys,

I'm currently running 4 Antminer S19s from my residential property. While I've managed to regulate temperature and airflow in the room they're in, noise containment remains a challenge.

My neighbours have raised concerns about the noise level. I've researched soundproof boxes, but options are limited here in the UK.

I'm also hesitant about attempting a DIY solution. Would mufflers and ducts be effective for noise reduction?

I'd greatly appreciate any suggestions or advice. Thanks! 🙏
