Major Airport Noise Levels Measured as LAeq 16h

Noise exposure data for major airports, including Belfast International Airport, measured using the LAeq,16hr metric and other standard noise indicators like Lden, Lday, Levening, and Lnight. The dataset is provided by OpenDataNI under the OGL-UK-3.0 license and was last updated on March 18, 2026. Available file formats include JSON, KML, CSV, SHP, GEOJSON, and HTML.

Use Cases

• Modeling community noise exposure based on the provided LAeq,16hr and Lden metrics.
• Assessing diurnal noise patterns using the separate Lday, Levening, and Lnight indicators.
• Conducting comparative environmental impact studies of different major airports.
• Creating geospatial visualizations of noise contours around airports using the provided KML, SHP, and GEOJSON formats.

Strengths

• Data includes multiple standardized noise metrics (Lden, Lday, Levening, Lnight, LAeq,16hr) for analysis.
• Available in several interoperable formats, including geospatial standards like KML, SHP, and GEOJSON.
• Last updated on March 18, 2026, suggesting recent maintenance.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The description metadata is limited; actual data quality requires manual inspection after download.
