The main objective of this paper is to validate a methodology, which allows to train an ANN model properly, in order to
predict the WPT range to reduce road traffic noise annoyance within a given population. The results obtained with this
methodology were compared to the econometric ordered probit model outcomes. The target variables used to adjust the
model come from a socio acoustic survey that collects the WTP of the respondents. Characteristics such as: (a) environmental
noise perception of the respondents, (b) modelled day-night noise exposure level (LDN) at the fac
