Brussels Airport noise disrupts sleep for over 104,000 in 2025
Noise pollution from Brussels Airport disrupted the sleep of over 104,000 people in 2025. The issue worsened in several areas, with sharp increases in reported disturbances. Almost 60% of those affected live in the Brussels-Capital Region. The latest data shows a 2.9% expansion in the 45-decibel noise zone, known as the 'L-den' area. Within the louder 55-decibel zone, the number of people classified as 'highly annoyed' rose by 7.4%. Reports of severe sleep disturbance also climbed by 2.5% compared to 2024.
The 'City of Brussels' recorded the highest number of complaints, with 16,643 residents suffering from disrupted sleep. Nearby municipalities like Schaerbeek (12,924), Sint-Jans-Molenbeek (10,596), and Evere (7,039) also saw significant numbers. However, Jette experienced a notable improvement, with a 35% drop in severe sleep disruption claims.
A new landing protocol introduced in summer 2025 led to a surge in complaints. Sint-Jans-Molenbeek saw a 54% increase in sleep disturbances, while Koekelberg reported a 47% rise. Research has linked noise pollution and sleep disruption to serious health risks, including heart disease. The 2025 figures highlight ongoing challenges for residents near Brussels Airport. Authorities may need to review noise mitigation strategies in response to the growing problem.
