im wondering if anyone can tell me a safe distance to have between a doof site and the nearest neighbours using a 10k system?

are we talking somewhere in the range of 2 km? or more like 10km?

cheers

It depends on heaps of stuff... mainly the lay of the land... if you can get a valley, and face the sound toward a wall, you'll muffle it heaps in the trees...
I *think* we found 12kms to be absolutley quiet, and insects and stuff drown out the sound (except the bass) from about 6 or 7kms... that's safe, if there aren't any neighbours (e.g. the middle of a SF or large property)

You can always get SF rangers to warn the locals of an event beforehand, which will reduce complaints, if you're strapped for space...

Whatever you do, DON'T face the speakers parallel with the valley or track... it funnels the sound to *who-knows-where*, in which case you could be doing soundchecks in the wrong place...


So... WHEN'S THE PARTY?!
:D

Depends on the geography - whether you're in a valley, whether you're on top of a hill, what direction you're pointing the system (ie, if you're in a valley and you project it down the valley the valley will carry the sound further). If you're near water (which carries sound very fast), whether it's open or there's a lot of trees (trees add insulation).

Generally, with a 10k system neighbours 2km away will hear it. 10km away? Maybe, maybe not. However regardless, it's common courtesy to inform all neighbours that you'll be there. They're far less likely to call in noise complaints in that situation anyway. Just 'cause they can hear it doesn't mean it disturbs them - it might only disturb them if they don't know what it is.

At PALA a party in the Wattagans a few years ago the police told us that they had received noise complaints from residents 20km away. The complaints came from down a valley but even though the party was at the top of the valley the speakers were not faced towards it. I'm not sure of the exact size of the rig at Pala but it was no more than 10K.

my sugestion is go to a camping store and buy a tropography map of the area you intend to have a party

it will show you where settlements are (and lown farm houses) it will show you in which direction valleys head and also it will show you where all roads (including fire trail) are for easy access and escape in emergancys

Q: Distance Sound Carries from a doof?

A: Depends on where the truck's parked.

Looks like the question has been adequatly answerd above. I alwaise tried for minimum of 3km behind the speakes and 5 km in front depending on topography etc. If in a valley beware of reflection of clifs etc this can throw sound a long way in unexpected directions as well.

BTW: our record for sound complaints was 42Km straight line or over 60km by road. At Earthdance 2002 we had 60kw on top of the highest hill in the area. Aparently a few weeks after the event someone told the land owners they herd it clearly at there home 42 away directly in front of the speakers.

Sound travels better (faster and further) with lower temperatures. If you do a soundcheck at day time then it wont be accurate because it gets colder when the sun goes to beddie-bys.
Problem is heat + contemporary Psychedelics = total body meltdown ie. heatstroke.

if you are doing an outdoor -get a good reference point (you don't have to have gps, but it can help - unless you are paranoid...) and clear a Helipad and take flares for signalling.
These things take forethought and need contingencies - no-one likes a tourist - stuff up an outdoor bad and all outdoors are shut, forever. full stop. you are now the news.

What about facing the speakers towards the ground. Ie Mounting them above the party and parallel to the ground?

We've had sound complaints from 6 miles (8km??) away even when using half the rig (5K) and surrounded by trees. It's so hard to judge

we should just set up a massive desert gig for next winter or autumn. only problem is getting out there. Sound would travel about 20 kms too, shit there is no way around it!!!!
I know, we do waterworld, doof out at sea, next speak like a pirate day, no. oh bother.
