Danish environmental law requires a noise contribution from road traffic at maximum LAeq,24h = 55 dB re 20 Pa (year mean day). When the construction project finished, measurements were made at the facades, in the courtyard and on the walkways. Compared to measurements Odeon 9 generally overestimated the values with 3-5 dB. At this moment there has been made no attempt to analyze why this deviation appeared.
