Các thành phố triển khai camera âm thanh để xử lý tình trạng đường phố ồn ào

Camera âm thanh được triển khai ở các thành phố Mỹ để giám sát tiếng ồn xe quá mức, nhằm xử lý ồn ào đô thị hiệu quả.

: Newport, Rhode Island đã triển khai hệ thống camera âm thanh để giám sát và xử phạt xe vượt quá giới hạn 83 decibel. Hệ thống này xuất xứ từ Châu Âu và trang bị cảm biến âm thanh tiên tiến, nhận diện nguồn gốc tiếng ồn và ghi lại vi phạm qua ảnh và video. Tại New York, các camera đã cấp hơn 2,500 vé phạt từ khi hoạt động năm 2021, thu về khoảng 550,000 đô la. Các ý kiến công chúng còn chia rẽ, nhưng nhiều thành phố cho thấy giảm rõ rệt khiếu nại về tiếng ồn sau khi áp dụng công nghệ này.

In recent efforts to address urban noise pollution, Newport, Rhode Island has adopted cutting-edge technology involving noise-detection cameras. These systems, which originated in European cities, use advanced microphone arrays capable of identifying vehicles responsible for excessive noise even in high-traffic areas, such as those exceeding 83 decibels. Sorama, a Dutch company, supplies devices that integrate license plate readers, capturing both photographic and video evidence of each violation. This automated enforcement represents a shift from traditional patrol and complaint-based methods to a more continuous and precise approach.

The introduction of noise-detection cameras in the United States is gaining traction, with New York City having deployed ten SoundVue cameras since 2021, resulting in over 2,500 citations. These have generated approximately $550,000 in fines, with penalties ranging from $800 for first-time violations to $2,500 for repeat offenses. Such data reflects the growing necessity to manage urban noise, exacerbated by increasing tourism and summer activities in cities like Newport.

Municipal officials, including Newport’s Police Chief Ryan Duffy, emphasize the effectiveness of these systems in managing mobile noise offenders as opposed to inefficient handheld meters previously used. Early results from Newport’s pilot program have reported numerous citations within months, prompting plans for citywide expansion. The city's initiative considers public input and statistical trends to deploy noise-detection trailers strategically in high-complaint areas.

The benefits of noise monitoring extend to health outcomes, with chronic noise exposure linked to sleep disruptions and cardiovascular risks. Urban planners document the correlation between effective noise enforcement and reduced violation rates across cities. While preliminary outcomes indicate a decrease in complaints post-deployment, long-term impacts of such technologies continue to be evaluated.

Public opinion on noise cameras remains divided, with some appreciating quieter urban environments and others, particularly high-performance vehicle owners, questioning the fairness of such measures. Privacy concerns linger, leading cities to define strict data retention policies, such as Newport’s protocol of deleting non-violation records and only issuing citations with clear evidence.

Legal challenges are emerging nationwide as courts consider the adequacy of these ordinances and technologies in addressing vehicular variability and driving conditions. Sustained technological success may depend on careful calibration, governance transparency, and community engagement, ensuring these innovations adapt to changing urban landscapes.
