To derive the decibel LA90 reading for a specific time T noise monitoring campaign, you would need to: Collect noise data over the monitoring period. Sort the noise levels in descending order. Identify the noise level that is exceeded for 90% of the monitoring period. This level corresponds to the LA90 reading, which represents the noise level that is exceeded for 90% of the time during the monitoring campaign.
