Adding relays to that field together with the rumour of bigger screens would really improve the experience. They would help with the volume in front of the repeaters too, as they would be able to cut the sound off at the edge of the arena. I love talking about PA tech, but hardly anyone here seems interested. Quote Link to comment Share on other sites More sharing options...
bamber Posted June 4, 2022 Report Share Posted June 4, 2022 My attempt at Rhapsody. It falls short I feel. An attempt at Rhapsody is better than abject dereliction of duty regarding Rhapsody though. Quote Link to comment Share on other sites More sharing options...

Rather the front array can protect it down into the crowd and the repeaters can ensure those further back can still hear. So louder up front without the bleed to other stages?

Whilst there's probably something in what @Mark H was saying, I was thinking about using the repeaters to reduce the sound at the arena perimeter. So, you know how headphone noise cancellation works? You record the sound coming in, then invert the waveform, which gets rid of the original sound. With clever software, you don't need to* record the sound to know what the waveform is going to be at any place in the arena - you can just using timings, since it's the sound from the PA you're looking to destructively interfere with, not any other sound. I don't have any source for this, but I've become convinced that clever modelling of the interaction between the repeaters explains why you don't hear a snare hit three different times when you're wandering around the Pyramid field. The repeaters are essentially pumping out negative sound* on a massive scale to ensure you hear a clean rendition of the performance in almost any part of the arena. Although it's not perfect - for instance you can hear the Pyramid up at Acoustic, on the whole sound bleed has been massively reduced over the years. You used to be able to hear W Holts at The Glade and listen to the Pyramid for the whole walk up to Acoustic. And if you've noticed that the Pyramid has been louder since 2014, that's because reducing sound bleed between arenas also lowers the off site dB levels. Having said all this, Other Stage seems to already be doing some clever stuff without repeaters - there used to far more reflection artifacts to be heard bouncing off the market stalls directly opposite the stage. But it seems like there's only so far you can go. Anyone who was unfortunate enough to be at the back of a packed W Holts field in 2015-2017*** will have heard what happens when destructive interference goes wrong. Not just quiet, but quiet in a weird, inconsistent way, where you'd think the sound engineer was on drugs. If you've ever wired up one of a pair of stereo speakers backwards, you'll have heard the effect as well. Just really bad sound. *There may well still be some monitoring going on to deal with wind. ** I might have just invented the term negative sound, but you know what it means, don't you? *** I think this started in 2015, but was definitely a problem in 2016+2017 Edited June 4, 2022 by stuartbert two hats 10 Quote Link to comment Share on other sites More sharing options...

When you say rather than recording noise to cancel sound you can use timings, how would this work? Quote Link to comment Share on other sites More sharing options...

Because they know how far one tower is from another and how fast sound moves, they can use that data to decide when the repeater need to play the inverse waveform. It's going be be slightly later than they play the normal sound that people are supposed to hear. Quote Link to comment Share on other sites More sharing options...

At Bearded Theory last week it was really windy on a couple of days and yet the sound was spot on all over the field whereas years ago it would drift with the wind.
