How to reduce noise level on S19j?

I have just recently received my S19j and it is super loud compared to my old antminer l3+. This thing is a beast! I’ve got it in the shed and I have sound proof the shed but you can still hear it. Is there any way that I can change the tuning to a less setting and make it less noisy?

yeah there are silencers that fit the S19 (search web for ASIC silencers). There is also a more extreme version which is called the Cooler Master Miner Pro but they are hard to find as there are many scam sites.
