  1. Hi, Have 5m x 3m outdoor stage with spoken word content at dusk, not full blackout. Single downstage lighting bar at 3m above deck top. I have a choice of two LEDJ Spectra Par futures: 15Q8 PRO or 12HEX10 PRO. Similar price. Same build quality. Similar beam angle. Same power consumption. True1 & 5-pin. The difference: 12HEX10 is RGB + W + A + UV and 3200 lux at 2m 12Q8 is RGB + W and 6,450 lux at 2m Appreciate lux numbers don't necessarily translate to perception. Which one should I deploy & why? Thanks in advance! Best Gareth
  2. Morning Stuart Simon is spot on with his advice, but I'd like to add a few observations. The Noise Council Code of Practice has indeed been criticised, but there is no commonly adopted alternative. In practice arguing for different noise criteria will be difficult unless you have some unique circumstance in mitigation. Would you want to be the Environmental Health or Licensing person who opens themselves to criticism from bosses or the general public for not enforcing the defacto standard? One of their objectives is to uphold the expected standards for protecting the public. In my experience the best approach it to proactively work with the responsible authorities, event organisers & residents to minimise the likelihood of complaint & therefore upholding the licensing objectives to prevent public nuisance. It is true that some local authorities have more experience than others with live music events, but assumptions are best avoided. These people will have often worked at a few different authorities & some will have diploma in acoustics. Sharing skills & expertise is a positive way forward. For example, you as a sound engineer will understand what PA configurations will help contain the sound where you want it as much as practicable, and how to mix a band that sounds full without necessarily operating at high volumes for long periods. In my experience avoiding complaint is the most powerful argument for what is a workable level that does not disturb residents. In practice, complaints do not always correlate to the perceived or measured levels. The general level of disruption overall, sensitivity to noise, what disturbance occurred in the preceding weeks (such as roadworks), fear of a repeat of a previous noisy event, the type of music and so on.. i.e. the music noise level is only one factor to the complaint. The criteria of a Music Noise Level of 65dB LAeq 15' at 1m from the facade of any noise sensitive premises is a default setting for 80% of events. The Music Noise Level is just the noise of the music & not the sound of everything else with the PA off (aka residual level). Achieving compliance depends on the activity & location. A rough calc will give you an idea of the kind of level you can expect in the audience. For example, let's assume: The event is on hard ground The site is relatively open & not excessively reverberant The nearest noise sensitive receptor is 40m off-axis from a point source loudspeaker You wish to achieve an average level of 88dBA for the audience 10m from stage over a 15 minute period If you calculate the sound power at the source, deduct attenuation for noise propagation over hard ground and apply corrections for off-axis response and facade measurements, a Music Noise Level of 65dB LAeq 15' could be potentially achievable. I have a bit of experience in the area, please PM if you would like to continue the conversation. All the best Gareth
