Editing Noise exposure (dB-hours) (section)

== Observational Status ==
Current monitoring of noise exposure is supported by a combination of fixed and mobile acoustic sensors, with increasing integration of real-time data collection technologies. Data availability varies by region, with more comprehensive coverage in urbanized areas. Future SIGNAL releases aim to enhance spatial resolution, incorporate standardized boundary definitions, and integrate noise exposure data with related environmental and health signals. Ongoing efforts focus on improving the temporal frequency of observations and harmonizing measurement conventions to support global comparative assessments.
