Warm air layer causes Rotterdam festival music to travel, triggering 66 noise complaints
The Environmental Protection Agency Rijnmond (Milieudienst Rijnmond, DCMR) received dozens of complaints Saturday evening about loud music from the Boothstock dance and techno festival held in the Kralingse Bos. Residents in Rotterdam and Capelle aan den IJssel reported being disturbed by the noise. By just before 9:30 p.m., the environmental agency had logged 66 official reports of nuisance.
According to DCMR, weather conditions on Saturday evening caused the sound to travel farther than usual. The agency explained that an inversion was occurring, in which a layer of warm air remains above cooler air near the ground. This acts as a lid that reflects sound back toward the ground, amplifying how far it carries.
DCMR noted that the low bass tones in particular were reaching greater distances than normal. The agency said it was continuously monitoring the sound levels of the event to ensure compliance with regulations. The festival ended at 11 p.m.
The Boothstock festival is an annual event that draws large crowds for electronic music performances in Rotterdam’s Kralingse Bos park.
