    Hi guys,

    Hope you can help.. Some friends are planning to have a small party in some foresty hills, and they really don’t want to disturb the neighbours, who live at the bottom of the hill 200m as the crow flies. The line of sight to the neighbours house is slightly blocked by hills here and there, but not much. My friends have a small active PA system, something like Mackie SRM450 V2 (GAK).

    Are the neighbours guaranteed to hear it if it’s tipped beyond a certain point? Are there any techniques in aiming the speakers that would help avoid the neighbours? What about aiming the music at the hill?

    Cheers everyone ๐Ÿ™‚

    alot of people seem to like to use walls of hay stacks to help reduce noise polution if you have any hay lying about (sounds funny for me to say that as I’m from suburbia but i’m aware some people actualy have spare hay lying about :laugh_at:)

    if you’re that close to the neighbours they might be just as likely to dob the party in on seeing the extra traffic before its even had a chance to get set up… most rural areas are on alert every weekend now for this sort of thing…. often its not the noise which is the issue these days but the fact you’ve dared to trespass on other peoples land (Forestry in some parts of the UK take a dim view of raves, two of my mates went to jail partly on their evidence!)

    might be worth going back to the drawing board (or one of the many on line mapping sites) and finding somewhere with less neighbours….

    What did your mates go down for? I was under the impression that if you were amicable with the police they’d generally be alright back and just tell you to shut the system down, and that if you left when the landowner asked it wasn’t tresspass.

    There is a plan to bring people in slowly.

    So I take it 200m is not enough distance at all, even with a small PA?

    Cheers

    200m isn’t far at all really anything louder then a home hi-fi (and probably alot of them as some go quite loud) will, i would imagin, be quite easily heard at 200m (at some bigger raves you can’t even get within 200m of the pa lol)
    It’s the bass you have to worry about as goes through most things

    Daftfader is right about the bass. I’m no expert in sound engineering etc, but 200m is not far at all. Maybe raising the speakers well off the floor is an idea, but the richness of the bass would be lost and anything like hay bales used as screens would have to be higher too.
    A new location is probably the best idea.

    As the others have said, doesn’t sound like a good location at all. There must be better places than that. House sounds way too close. Depends how loud you have it though and as to legal risks I would think it very much depends now big the event is, how well you chose the location and if its private or not. But having never organised a party in my life I wouldn’t put any faith in my words.

    holding a licensable activity without the relevant license… even one of the cops in charge said he thought the penalty was harsh but at the same time this did happen in East Anglia where both sides wanted to be stubborn with predictable unpleasant results.

    the whole criminal justice system wanted to make a stand that property rights and licensing laws were to be respected however inconvenient they may be.

    these days even if the cops let you get away with the rig they may well still start searching people and asking unwanted questions…

    200m is way too close. most people would dial 999 if they saw a load of young people in cars turning up virtually next door to them even if they were a very friendly and good natured crowd….

    Ok then, my mates have found a new venue, in a forest clearing about 1km and 1.5km respectively away from the only dwellings for miles. Both dwellings are slightly downhill and there is a mixture of dense and sparse forest in between the venue and the dwellings.

    Is this any good? Would aiming the speakers away from the dwellings and/or aiming the sound towards a centre point so that it diffuses in an X direction help?

    Are there any other steps that could be taken, e.g. strapping carpet to the back of the speakers, putting them on stands, and/or putting a bunch of fabric behind them if they’re on the floor?

    Cheers for the help guys, muchly appreciated

    That sounds like a MUCH more sensible place!

    sound ecko’s through vallys so the best thing to do would be stop the majority of the sound b4 it gets too far out … make a ring of hay bales as high as the speakers and make it into an arena where you dance inside and the speakers are allso inside.

    yeah 200m isnt very much at all, unless your allowed to do it there and let the people that close know then i wouldnt bother with the hassle,

    with two mid/tops and a usb sub you could hear clearly what type of music was being played from over a mile from a mates field, got complaints from all around and he was in a small marquee surrounded by trees on 2 sides and a long slope on the other.

    If you can find something solid to aim the direct dispersion from the speakers (ie what comes out of the front of the boxes) you will get much less leakage – we tend to use hills (of which there many in Scotland), and you mentioned it being a foresty/hilly area. The main thing is to get something solid between the speakers and any place where the leakage would cause a problem (the hay bales idea is a good one too, as hay bales would work in a similar way to the foam used to soundproof studios)…

    Echos and reflections are much less of a problem, as the intensity of the sound is greatly reduced when it’s reflected so I wouldn’t worry too much about that – the important thing is to get something to interrupt the direct path to anyone who might complain.

    Most of the time when people put sound equipment into valley’s, there is a tendency to point it along the line of the valley – never worked out why, as thats the easiest way to get noise complaints, but in my experience it’s what happens. If they set up at right angles – ie pointing into one of the hills, they would have far less trouble (as I say, this is how we always set up, and we never get noise complaints :love: )

    Yeah come to think of it every party I’ve been to that I’ve heard miles away all were pointing the same way as the vally! One party actualy got quiter the closer we got untill we actualy got there where obviosly it got very loud – this was because of the way the sound way echoing all down the vally and around the pathway to the place and past the road further out (what was in a vally).
