Using acoustic curtains outside

(1/1)

Annix:
Hi,
So pleased to have found this forum. I would really appreciate some advice. I'm looking for ways to reduce noise coming from my roof terrace as a courtesy to my neighbour who overlooks us at the back. Several evenings each summer I have to hold group suppers late at night as part of a festival I organise. We try to keep the noise down, and have no music (for example) and although my neighbour is begrudgingly accepting of the situation, I would love to find a (preferably temporary) way to at least reduce/absorb some of the noise. Researching on the internet I've read that hanging thick fabrics can help and I have been looking at professional, acoustic sound-absorbing curtains that are used in theatres etc (500g weight). Would these do anything at all if they were hung from our pergola (wooden, bamboo/cane roof) along the side that gives onto the neighbour's house? I'm prepared to take a gamble if there is a chance they'll work (even if it's impossible to say beforehand exactly how effective they will be) but won't bother if they categorically won't do anything.
Many thanks in advance for your thoughts.

as long as you get the acoustic curtains that have mass loaded vinyl in them, you would see some value of reduction.
How much reduction is to be determined.

Annix:
Hmm, I'll have to check up on the ones I've seen. I'll investigate. It's good to know they may do something at least. Many thanks!

Annix:
I'm not sure what mass loaded vinyl is....but I've checked and they're 100% cotton (? sounds like a "no").

here is a link to the manufacturers page to see what real acoustic curtains look like
