| Parameter | Description |
|---|---|
| LAeqT | A-weighting equivalent continuous sound pressure level |
| Lden | Day–evening–night level |
| Lday | A-weighted average sound level over the daytime period 07:00–19:00 |
| Levening | A-weighted average sound level over the evening period 19:00–23:00 |
| Lnight | A-weighted average sound level over the night period 23:00–07:00 |
| LAmax | Maximum A-weighted noise level during the measurement period |
