The project is related to previous years’ DTU - Acoustics projects also concerned with influence of one stage over the other while incorporating known environmental data. As a collaboration between DTU, Roskilde Festival and Meyer Sound, the reasoning and purpose of this project is to identify the interference present between each of the individual stages (Apollo Pavillion and Orange stage) and the potential optimal arrangement of stages to allow for a better audience experience.
With the use of a fiber optic connection between each of the stages and by recording the sound coming from each stage before and during the festival, a sight survey was performed of the amount of “spill” of sound from each stage to another. The reference signal was acquired directly from the front-house audio mix after in was LP filtered and with the use of the fiber optic cables, the project team was able to capture and record all stages simultaneously with the low latency reference signal while concomitantly recording the stages that were active by placing microphones at the stages which were inactive, allowing for a synchronized correlation of all the signals that were present in the recording and the reference signals.
Thus far, the results are showing significant effect of one stage to the other, resulting in fairly coherent signals at the points of measurement. The results of this project will define the extent to which this may be problematic for the audience and the festival, paving the way for methods of restricting the sound (e.g. Sonic Crystals blocking certain frequencies) of each stage to the areas of interest.
