Editing Noise exposure (dB-hours) (section)

== Aggregation Semantics ==
Geographically, noise exposure data are aggregated across spatial units such as neighborhoods, urban districts, or broader regions to assess community-level exposure patterns. Temporal aggregation involves frequent measurement intervals, enabling analysis of daily, weekly, or seasonal exposure variations. Cross-signal aggregation may integrate noise exposure with related environmental stressors or health outcome signals to evaluate combined effects. Aggregation semantics ensure that noise exposure metrics are contextually meaningful and support comparative analysis across geographic and temporal scales within the SIGNAL framework.
