LAeq - A-weighted, equivalent continuous sound level

To be able to obtain NAx results for a certain traffic, the following columns are needed on its file:

• track_name
• profile_name
• event_count

Echo will also apply corrections to the individual events (as dB) if the column correction is present in the file.

Check the Upload Traffic Files page for more information on traffic files upload and for details on each column of the file.
