This weekend, 10,000 smart wristbands are distributed to the Woodstower festival goers, inviting them to be part of the light shows during the evening concerts.
The Woodstower festival is a celebration of the last summer weekend with music, lake swimming and entertainment, and it is the first festival outside the project to try out MONICA solutions, which besides light shows also include crowd and sound level monitoring.
Light shows and crowd density
Volunteers are distributing up to 10,000 MONICA smart wristbands with LED lights that will flash in synchronisation with the music played on each of the four stages.
Additionally, the crowd wristbands are tracked (anonymously) so that the organisers can get an overview of the crowd density by the display of a crowd heatmap.
Monitor sound level and level of annoyance
Besides boosting the crowd experience, the festival is also interested in monitoring the sound levels.
Inside the venue, four IoT-enabled sound level meters are automatically collecting and transmitting the acoustic measurements and displaying them in real time as a sound heat map on the COP.
Another four sound level meters are placed in the neighbouring communities to evaluate the level of noise annoyance. On the COP, the festival staff can see an index of ‘annoyance likelihood’ that takes into account the subjective perception of noise.
Estimate the sound exposure in the audience
A final aim is to estimate the sound exposure in the audience by comparing the positioning data of the crowd wristbands with the sound level data from the sound heat map.
This approach is done in the light of a new French sound regulation, coming into force in October 2018, which sets limits on sound pressure levels in the audience.
