Street Noise-Level Dataset — Regulatory & Governmental Use

Silencio’s Street Noise-Level Dataset provides regulatory bodies, governmental agencies, and public health authorities with the most reliable and detailed data on environmental noise worldwide. Built from over 35 billion datapoints, collected via our mobile app and enhanced through AI-powered interpolation, this dataset covers hyper-local average noise levels (dBA) across streets, neighborhoods, and cities in over 200 countries.

Our dataset is specifically suited for noise regulation, environmental impact assessments, policy-making, and compliance monitoring. It offers objective, real-world acoustic data that goes beyond traditional noise models by combining actual user-collected measurements with AI-predicted values. Authorities can use the data to map noise pollution hotspots, monitor changes over time, enforce regulations, and inform sustainable urban and environmental strategies.

Silencio also operates the world’s largest noise complaint database, giving policymakers a unique tool to correlate objective noise exposure with subjective community reports for more people-focused decision-making.

Delivery options are flexible, including: • CSV exports • S3 bucket access • High-resolution image maps suitable for integration into reports, GIS platforms, or public communication.

The dataset is available both as historical records and continuously updated data. An API is currently in development, and we are open to early access discussions and custom integrations tailored to government and regulatory workflows.

Fully anonymized and fully GDPR-compliant, Silencio’s data supports transparent, evidence-based environmental and public health decision-making.

To that end, the data provided for regions includes Monmouthshire within the “Welsh counties”.However, for the purposes of the 1921 Census outputs, Monmouthshire was generally included within England. In some of the printed tables, figures were given for both “England including Monmouthshire” and “England excluding Monmouthshire”, likewise for Wales. These additional breakdowns are not being included within the digitised data at this time and for the purposes of dissemination on Nomis, Monmouthshire has been included within England only to align with the majority of printed tables. As such, any user aggregated data from regions to country will not match figures given for England and for Wales on Nomis.
