djmatthill Posted June 11, 2017 Share Posted June 11, 2017 Hi All I'm in the process of setting up a Dsp soundweb for a client in a bar that is very near residential properties. Previously DJs have been causing headaches with playing too loud. The LF is causing the complaints and in a bid to sort this out we ve set the Soundweb to limit and Process using various High Pass filters etc.... My question is.... Do you think sticking a 2nd limiter Component after the LF output on the Crossover section would help and be usable! So if the DJ cranked up bass the HF would still remain unaffected but the LF would cut... It would sound bad, but hopefully this would encourage said DJ to turn things down a little... Your thoughts please.. Link to comment Share on other sites More sharing options...
Jivemaster Posted June 11, 2017 Share Posted June 11, 2017 My thoughts. If the venue has noise issues with neighbours then DON'T BOOK DISCOs, DON'T ALLOW DISCOS. Remember that the neighbours control the drinks licence! Basically a disco is a 105dB sound source for 1 - 3 hours and a cause of noisy spill out onto the pavement for smokers. If the venue want the disco then they have to provide 100dB noise barriers. Link to comment Share on other sites More sharing options...
Stuart91 Posted June 11, 2017 Share Posted June 11, 2017 Have a look at some of the volume controllers that Formula Sound make. They are not cheap (but far less expensive than the venue losing its licence). They can actually bring the output volume down when the input volume exceeds the threshold, so they "train" the DJs to sit in the sweet spot. However, as Jivemaster suggests above, if the venue is unsuitable for these kinds of events you may well be fighting a losing battle... Link to comment Share on other sites More sharing options...
djmatthill Posted June 11, 2017 Author Share Posted June 11, 2017 Cheers Guys .. The bars main theme is DJ led Entertainment so pulling the DJ aint an option. To be fair the bar has been running nicely for over 10 years without any problems. I think the change of modern music styles being more "Bass Heavy" coupled with the fact"Experienced and Professional DJ`s" who know how to work to limits and good structure are a rare findthese days has necessitated the need for this... The Venue currently has a soundweb unit and are not looking to change this .... Just after some real world tips on how YOU GUYS have overcome this type of issue using clever DSP tools/settings Link to comment Share on other sites More sharing options...
dosxuk Posted June 11, 2017 Share Posted June 11, 2017 You should be able to build a Formula Sound style effect with some meter trigger objects and preset recalls. If you're not familiar with what they do, they basically act as a really rubbish compressor, attenuating the feed in more and more severe stages as the input level goes up. They also work impressively well at training the DJs as to what level you want them to play at - if they go over a bit, they'll hear it get a little quieter, if they go over a lot, they'll hear it get a lot quieter.

Jivemaster Posted June 12, 2017 Share Posted June 12, 2017 Suggest you consider what the clients want -the pub's punters after all they pay to buy the beer -no punters no profit. Remember that they now smoke outside so take their personal noise out with them. The DJ is there to play loud music. The punters come for the loud music. It's up to you to keep the music loud inside and quiet outside. OR change to ballroom dancing. It's NOT the DJ's fault that they play to the crowd, it's the pub company's fault that they want what the neighbours don't want. Link to comment Share on other sites More sharing options...

Mr.Si Posted June 14, 2017 Share Posted June 14, 2017 Long time no post. I get involved in sound installations where noise breakout is also an issue prior to the installation going in. As an acoustician, for me it's not just about limiting the sound level at source that is an issue as sometimes it's unavoidable, but the building shell is also something major to consider. What is the condition of the venue's building envelope? (i.e. walls, floor, ceiling, windows and doors)? What is each element made from?Are there any obvious points where sound easily leaks out that can be dealt with? (i.e. closing windows where possible, if ventilation can be achieved by other means, using a double-door set or sound lobby to help prevent sound leaking out via this route, or using a well controlled venue entry/exit system). Otherwise, I'd second the use of a formula sound Sentry Mk2 with an AT1 unit in line with the system prior to sending to the amps or powered speakers, along with the use of a beyer dynamic measurement microphone (much better than the sentry's own one in the unit) as you can place it in the most relevant place, which is often remote to the sentry unit. If needs be, get an acoustic consultant to help you - they're often more willing to assist with mitigation measures than an Environmental Health Officer who's been called by the client (though some EHOs are very sensible and understanding). Just some food for thought... Simon Link to comment Share on other sites More sharing options...
Jivemaster Posted June 15, 2017 Share Posted June 15, 2017 There are schemes of distributed speakers in the ceiling that beam the sound into a small space with lots of sound at ear level but little spill. BUT once someone goes to the bar they are outside the sound and may not hear tunes they want to dance to. Silent disco systems have the same effect -people with cans hear disco the rest hear nothing. Can be fun with two circuits one with club and one with pop and two sets of people dancing to different beats. Double glazing double glazed with another double glass will help, if they are both screwed shut. BUT then the air handling must be adequate to maintain a normal temperature without leaking sound out or generating it's own noise. The best quiet disco was next door to my old house. At 2 metres we never heard anything because it was in a sealed bunker/basement with sound trapped doors and ventilation. Can your pub move the disco into the basement? Outside quietness also depends on the punters leaving/smoking quietly outside, not peeing in the neighbours gardens, and not throwing litter and condoms there. "Security" must include constant and near instant litter picking. No neighbour wants to see their garden used as an ash tray/litterbin etc. Above all neighbours complain if they don't like the music.

Doug Siddons Posted June 20, 2017 Share Posted June 20, 2017 I would decide the " acceptable" level then set the output limiter to be a brick wall so as they push the system it gets quieter, justa thought. Link to comment Share on other sites More sharing options...
Simon Lewis Posted June 20, 2017 Share Posted June 20, 2017 I agree with Simon - it's worth checking the building in detail first to see where the problems arise and what might be done to mitigate them. Whilst spaced triple glazed windows etc. can be quite good at resisting the passage of sound, placing them in a lightweight wall construction or having an air vent nearby can undo any expected advantage. Similarly, having been involved with sound systems at Students Unions, it's not unusual for limiters to simply have the XLRs unplugged from the back panel and joined together to bypass the unit. Although some DJs and performers may comply, there are others who will go to great lengths to play at the volume they think suitable or necessary to get "their" sound...
