• The authors see Noise as having become a major environmental price that contemporary societies have to pay for living in densely urbanized environments.The impact of this externality upon the quality life leads to a diminishing on the level of the household welfare and, consequently, to a reduction in property values. Bu using hedonic pricing models (HP), a signifi cant number of studies have assessed the impact of noise upon real estate values. They quote the meta-analysis made by NAVRUD (2002) which demonstrated that for each dB of noise growth, the price of housing is reduced on an average of 0.64%. In their paper, by using a geographically weighted HP model, which allows for a considering of soft boundaries between submarkets while at the same time solving space dependencies, the impact of noise upon a sample of multifamily housing in Barcelona is investigated.

  While the results indicate that actual noise levels reduce the value attributed to dwelling space, unlike other studies: 1) in Barcelona the noise depreciation sensibility index (NDSI) is lower and 2) the willingness to pay, resulting from a contingent valuation is greater than the implicit price of noise.
