In 2025, São Paulo witnessed a staggering rise in noise complaints, with nearly 50,000 grievances reported to the Urban Silence Program (Psiu), marking a 14% increase from 2024 and a striking 111% rise since 2012, when record-keeping began. These complaints are pervasive across the city, spanning from central neighborhoods to the outskirts, highlighting a growing concern among residents about noise pollution. Despite the city's efforts to address these issues, only about 37% of the complaints received were addressed, pointing to potential shortcomings in the city's noise management strategies.

The administration of Mayor Ricardo Nunes (MDB) has stated that it has intensified enforcement against noise violations, issuing 844 guidance terms, 788 fines, and 119 administrative closures of offending establishments last year. In contrast, the previous year saw significantly lower numbers, raising questions about the effectiveness of their enforcement measures. This inconsistency in noise management could be contributing to the rising complaints, suggesting that residents feel their concerns are not being adequately addressed by local authorities.

Adding to the complexity, the São Paulo city government has been attempting for over three years to relax the noise limits for large events, indicating a potential conflict between accommodating public entertainment and respecting residents' right to peace. The city's recent appeal to the Supreme Federal Court (STF) for assistance in this matter underscores the ongoing tension between urban development needs and quality of life for citizens, as officials navigate the challenges of noise management in a bustling metropolis.
