Many venues have Noise Limiters and we work with them on a regular basis.
They are to ensure no disruption to neighbours and they cut the power for a while if a pre-set volume is exceeded.
We’re quite happy and accustomed to working with Noise Limiters.
… but please note all limiters are set to a different volume relative to the needs of the venue and how close the neighbours are. Some cut the music when it’s quite loud (so this shouldn’t affect your Party) whilst others are set VERY low, so this may well affect your Party atmosphere.
My advice is to try to ask someone else about their experience of a Disco at the same venue or try to pop along to another Party at this venue whilst a Disco is in operation there to see if you think the volume is loud enough for you.
