This work reviews the literature of 46 peer-reviewed papers and presents the current status on the use of psychoacoustic indicators in soundscape studies. The selection of papers for a systematic review followed the PRISMA method. Afterwards, descriptive analysis and principal component analysis (PCA) were realised. For the PCA, the following parameters extracted from the papers were analysed: psychoacoustic indicator, hypothesis, statistical units, data collection method and major findings for each investigated psychoacoustic indicator. The results show an overview of the use of psychoacoustic indicators, through main hypothesis and findings for each psychoacoustic indicator i.e. the importance of statistical units, such as percentiles, to investigate the hypothesis related to the description of auditory descriptors and perceptual attributes. Another important finding is that many papers lack the specification of computation methods limiting the comparability of study results and impeding the meta-analyses.

Purpose of review: This study aims to investigate anthropogenic noise impact on avian species by means of a systematic review of literature. Recent findings: Based on previous anthropogenic noise impact frameworks, it was possible to: clarify the impacts of noise on birds; optimise the existing frameworks with findings produced over 44 years; recategorise noise impacts into more appropriate categories, indicating which are the positive and negatives, as well as acute and chronic impacts caused by anthropogenic noise; provide a significant cluster model of anthropogenic noise impacts on avian species subdivided into impacts on ‘Behaviour’ and ‘Communication/Perception’ (Cluster 1) and ‘Physiology’ (Cluster 2); and show how avian hearing frequency range overlaps noise source frequency range. Summary: This research adopted the database of Peacock et al. [1, 2] regarding avian species due to its vast coverage across taxa. A systematic literature review of 50 peer-reviewed papers about anthropogenic noise impact on birds was undertaken. A Two-Step Cluster analysis was calculated, showing the data subdivided into two clusters. Cluster 1 (76.9%) showed behavioural responses mainly composed of negative and auditory perception and communication impacts, presenting positive or negative noise impacts. Cluster 2 (23.1%) mainly showed negative impacts on physiological outcomes caused by traffic, anthropogenic, and background noise.

The purpose of this study was to assess the noise generated by a major urban expressway (Green Line) and ascertain the influence of its propagation in the surrounding area. To this end, noise was monitored on the expressway and adjacent thoroughfares at a total of 31 measurement points. Noise mapping was also performed, and noise perception interviews were held with 397 interviewees. Noise measurements were taken using B&K 2238, B&K 2260 and B&K 2250 sound level meters. Noise mapping was performed using B&K Predictor 7810 software. The results of the noise measurements and mapping indicated that the urban expressway under study contributes significantly to noise pollution in the region, as well as to noise coming from the secondary thoroughfares. However, owing to the urban zoning of the area in question, the interviewees stated that the noise in the region does not annoy them (56%), while those that feel annoyed (44%) complained most frequently about the noise coming from the secondary thoroughfares adjacent to this major urban expressway.
