Sound proof 'bunker' for festivals?

Same as for any temporary building I would guess.

Such is the nature of a litigation led society...!

At one time people were expected to exercise common sense. Nowadays, they don't have to, because they can blame it on someone else!!

Hi all,

My wife, son and I are regular Woodford (and other roots music) festival attendees. I gotta say that that there are better ways to approach the sound spill problem than building stuff.

In the case of Woodford, the site is huge. You come in through the camping area and then pass through an inner gate to enter a valley where all the stages (all temporary) are located. Well up the valley is a natural amphitheatre where the fire event and other big things take place. Up till a few years ago, it was also used for nightime rock concerts.

The lay of the land keeps the sound away from the rest of the entertainment area - although it does reach the performers camping area (but they're up all night jamming anyway so it doesn't matter).

Conversely, during the day, the amphithetre is mostly unused and isolated from the sound of the rest of the festival. It's a bit of a walk but maybe a good place to do a bit of a capella singing.

Two years ago, rock started to feature significantly in the daytime program at Woodford and events were sited in the centre part of the entertainment area. That year, there was also an unexpected increase in numbers and the organisers chose to enlarge the venues and PAs. As a result, we had to listen to some our favourite sacred music with a doof-doof backing - which really sucked. Consequently, we didn't go last year and, I understand, were not alone. We understand that the message got through and we're going this year.

For those festivals which take place on univerity, college or school grounds, it's usually pretty easy to find a quiet room.

Been away for a couple of day's cos an humungous electrical storm fried my phone and power.
I think the technical side of things is easily possible, that could be by alternative configurations of stages and maybe some sound reduction measures.
Many other considerations have to be considered with the layout.
What I am trying to stir up is the idea that quite a lot of people would like a quiet zone to be available, let's call it "The Oasis" (no camel jokes just yet thanks).
I think that would make things nicer at the big festivals.

I might be an old phart but I enjoy nice quiet music as well as a bit of
Wock n Woll.

That suggestion is sure to give a lot of people the hump.

Guest ace -
Sound cancellation technology is cool, but I don't imagine it would work in a festival venue. The headphones produce a cancelling sound wave that is equal in volume to the offending noise, but 180 degrees out of phase. The trick is the offending noise is canceled at a known point -- right as it enters the ear.

Out in the 3D world you would still need a cancelling sound wave as loud as the offending noise and exactly 180 degrees out of phase. The problem is that the cancelling souud can't be "as loud" and "out of phase" in all parts of a large 3D space at same time.

The device that that stops bass from coming through the wall seems plausible. With a little tweaking and tuning you should be able to push back on a 2D wall with an equal but opposite force to the offending, incoming sound and stop the wall from vibrating. It seems like it would work best attached directly to the wall, but I'm just speculating. This sort of device might be useful for building your bunker out of cheap, portable materials.

I got an idea!!
Just been doing an bit of work that involved an old 20 foot shipping container.
Noise reduction even with just one empty container is very good.
No...we don't go inside and close the doors!
We arrange 4 (or more) of them in a rectangle with suitable gap for a doorway.
Festival organisers could very cheaply rent the containers for the event, the containers could at the same time be used for secure lock up.
This would create the bunker effect and the hard walls provide a nice resonance as an added bonus.
Wocha reckon?

Great idea - provides secure storage for the beer, sound equipment and other stuff! Tarpaulins could be stretched across when it rains.

Bodhran players would, of course, play inside one of the containers... ;o>

What a brilliant idea!
They could be locked inside at the end of the festival which would save them the cost and effort of travel the following year. Heck, next time round they wouldn't even need to buy a ticket!
