Potential quiet areas in Europe based upon the quietness suitability index (QSI)

Figure Created 15 Jun 2016 Published 15 Jun 2016 Last modified 25 Aug 2016
The quietness suitability index (QSI) provides the overview with the highest (QSI=1) and lowest (QSI=0) proportion of potential quiet areas in Europe.

Methodology:

Suitable distance layer from noise sources built following a fuzzy approach (*), calculating the 'membership' to the quietness range (0–1) by means of a linear relationship, considering the mean value obtained as no suitable (= 0) and maximum distance obtained as suitable (= 1). The distance values between not suitable (mean value) and suitable (maximum value) will be reassigned with a new value between 0 and 1 following a linear equation.

 (*) The production of threshold distance layers around noise sources has been made following a fuzzy approach rather than obtaining a buffer with sharp limits. Membership to a 0-1 range has been obtained according to a linear function.
