Modeling and Mapping of Combined Noise Annoyance for Aircraft and Road Traffic Based on a Partial Loudness Model

Abstract

Complex transportation systems often produce combined exposure to aircraft and road noise. Depending on the noise source, the annoyance response is different, and a masking effect occurs between the noise sources within the combined noise. Considering these characteristics, partial loudness was adopted to evaluate noise annoyance. First, a partial loudness model incorporating binaural inhibition was proposed and validated. Second, short- and long-term annoyance models were developed using partial loudness. Finally, the annoyance of combined noise was visualized as a map. These models can evaluate the annoyance by considering both the intensity and frequency characteristics of the noise. In addition, it is possible to quantify the masking effect that occurs between noise sources. Combined noise annoyance maps depict the degree of annoyance of residents and show the background noise effect, which is not seen on general noise maps.

Use of noise prediction models for road noise mapping in locations that do not have a standardized model: a short systematic review

“…Urban noise can come from different sound sources such as aeronautical (Grigolato et al, 2018 ; Lee et al, 2021a ), road (Morillas et al, 2021 ; Cai et al, 2019 ; Yang et al, 2020 ), railway (Lee et al, 2021b ; Wosniacki & Zannin, 2021 ), industrial (Bozkurt & Demirkale, 2017 ), ports (Fredianelli et al, 2022 ), and mining (Lokhande et al, 2018 ). Thus, this paper aims to identify, select, evaluate, and synthesize information on the use of different road TNMs and the different noise mapping software used in countries that do not have a local TNM.…”
