Resumen

The influence of applying European default values to the making of a noise map was evaluated in a typical environment like Palma de Mallorca. These default values were compared with measured noise levels and the model was validated or rejected according to the deviations. After an unacceptable initial result, quantification of improvements to the process has been performed. This analysis demonstrates that the use of noise source default data in the absence of specific data can generate deviations in excess of more than 9 dB. Consequently, additional data gathered were of higher quality and were collected using different techniques. Different methodologies were also examined for collecting model input data that would be of the highest possible quality, by analysing the improvement generated in the reduction in the uncertainty of the final result of the noise map. Improvements to the process consisted of a developing a new traffic network with current data, obtaining more experimental data with a greater geographical sampling of traffic, implementing a new road categorization system and using alternative techniques to obtain the composition and speed of traffic.
