do i need ducting on both sides of the box or just one ?

You certainly need to be able to move air in one end and out the other.

Of course both side (that's why called as soundproof). Are this is DIY soundproof box? You also must be considered about heat handler (as above said), many ways to do it. May you should be made DIY cooling systems and add it to the box.

Soundproof boxes that are heat compatible are not new. There are lots of online guides and tutorials out there that teach you how to make or buy these types of boxes. All you have to do is search them. If you're not familiar with DYI or don't have any tools at home though, I would probably just ask a local carpentry shop or hardware to make it for you.

If you're looking for soundproofing guides, here's two guides that I have saved on my browser.

This (https://bitcointalk.org/index.php?topic=2245487.0) guide by philipma1957 is more oriented towards BTC miners like the S9 and S7, but it should also work for the D3. Fire resistant, fits 2 Antminer-sized units and works very well.

This (https://steemit.com/bitcoin/@cloh76/building-a-soundproof-enclosure-for-my-bitmain-s9-bitcoin-antminer-my-building-journey-video-included) enclosure also seems to be somewhat fireproof and should work decently, but it only fits one unit. Cost for this is around $120.

If you decide to purchase something for soundproofing, don't go for something like this (https://m.ebay.com/itm/Antminer-Airflow-Noise-Reducer-4x12-Silencer-D3-L3-S9-APW3-Bitcoin-Miner-NEW/142672723070?epid=2210595051&hash=item2137f4fc7e:g:AvkAAOSw3wVab3xC). This type of noise reducer hardly does anything and you're better off with the two solutions I linked above.
