• 
Noise measurements may be used: –  to validate noise maps at selected sites, boost public confidence in these maps, –  to help develop detailed acLon plans and, –  to show the real effects of acLon plans once they are implemented. Noise measurements may also be needed to determine emission levels or base levels from industrial processes.

There are a wide range of noise measurement standards but most of them were not originally designed for noise mapping and therefore need to be adapted. • 
The selected methodologies must comply with the aims and accuracy of the strategic noise mapping as well as the available resources. • 
The fieldwork evidences the difficul4es for fulfilling the standards’ requirements so methodologies need to be adapted to the real condi4ons. • 
Decisions must be based on acous4cal criteria to guarantee the consistency of results.
