Therefore, during one of the two sports activities on 7 and 8 September, the sound must be reduced to 72 dB. And during two of the four days of the concerts, 11 to 14 September, the volume must also be reduced. Sportworx may decide for itself, according to the judge, on which days the sound level must be reduced and on which days the sound remains at 80 dB. On the last day, 15 September, the concert of Zomerstadion lasts until 20:00 and the musical starts exactly when the concert is over, so there is no nuisance then and Sportworx does not have to do anything about the sound.
