Reducing noise levels of a shed

Squidgy Black

We're looking to reduce sound levels in a new shed, it's metal but pvc coated, with 40mm kingspan insulation.

I've been doing a bit of internet trawling, and there seems to be a lot of debate over acoustic foam and whether it actually absorbs any sound. Same with carpets on the wall.

We're not looking to soundproof the room totally, just reduce the levels so trackings drums and loud guitars etc. are more manageable and keep complaints away.

The sheds 5mx3 if that makes any difference.

Acoustic foam and carpets are for changing how it sounds IN the room. They will do nothing for soundproofing.

You will basically need to build a new room inside your shed, with an air gap and a large amount of mass separating it from the walls of the shed.

Before I describe that or give you links, are you prepared to spend the money to basically build a new shed inside the existing one?

I'm not looking to soundproof the room, and building a room inside the room's out of question as it's a tight space as it is.

I'm really just looking for an easy way to make it quieter by a few db, but nothing excessive like total soundproofing.

Sorry but it's not easy, and yes, you are looking for soundproofing, albeit not much (whatever that means). Unfortunately half measures are not recommended, they will cause other problems I think.

You can try sealing up all the air gaps where sound can leak out. So door seals on all four edges of the door(s), block up old vents, etc. If you've a window, put a second window inside it with as thick a glass as you can, seal the frame in well and ensure that the outside frame is totally sealed too. Double glazing is no good.

That should get you quite literally a few dB less sound leakage. However it may cause problems with air circulation and dampness. As I said, half measures like this are not recommended!

If you want something effective, but not too complicated, acoustic plaster board should help a good bit. if possible, connect it using resilient bars.

ATIL in Dublin should be able to supply this.

Good idea shayleon. Never experienced that stuff, does it work?

Just be aware that the effect of that will be completely negated by any holes that allow air (and therefore sound) to leak to the outside.

Insulation here is with that + rockwool + led impregnated rubber and it works.
