N22 Review

Client: National Roads Authority (NRA)

This project involved a review of the Noise and Vibration impact assessment chapter from the EIA. Baseline noise data as previously measured was used to validate a computational noise model (CadnaA) and the Lden value was predicted at residential receptors along the route. Suitable mitigation measures were subsequently recommended to the client.

The consultant for this project was David Cawley however this may not have been with Allegro Acoustics Ltd.
