Estimation of field psychoacoustic indices and predictive annoyance models for road traffic noise combined with aircraft noise

Abstract

Annoyance due to urban road traffic noise combined with aircraft noise was studied using both laboratory and field survey data. Laboratory data were used to propose (i) partial annoyance models considering psychoacoustic indices and noise sensitivity, and (ii) total annoyance models considering noise indices or partial annoyance models. To predict partial and total annoyance in field, a methodology was proposed to estimate the different psychoacoustic indices, involved in annoyance models, from L_denvalues. This methodology, interesting from a practical point of view, and the proposed annoyance models enable a good prediction of the field partial and total annoyance ratings compared to models based on L_den only. These results show that there is a need to develop the methodology of psychoacoustic index estimation from noise map L_den and also partial and total annoyance models.
