“…Previous studies ( Jang et al, 2015 ; Michta and Haniszewski, 2018 ; SAE International, 2020 ) have suggested that study sites should be selected based on the relationship between traffic volume, vehicle speed, and noise levels. This takes into account the different noise levels generated by varying levels of traffic volume and vehicle speed on the roads.…”

IntroductionThis study aims to investigate the interplay between roadside trees and pedestrians’ assessment of traffic noise and comfort. The study examines the potential effects of visual and design elements of roadside trees on the overall soundscape comfort.MethodsThe study design involves a systematic exploration of different conditions, encompassing traffic volume, distance from sound source, and tree density. For each combination, two experimental scenarios are created: (1) participants experience a binaural sound recording exclusively, and (2) participants experience the same binaural recording while concurrently immersed in a virtual reality (VR) video.ResultsAnalysis of participants’ noise perception, measured using a quiet-noisy scale, reveals no significant disparity between conditions. This suggests that the mere presence of roadside trees does not necessarily lead to a perceived reduction in noise loudness. However, evaluation of sound intensity exposes a notable discrepancy between low and medium tree density levels. Furthermore, the study confirms the impact of roadside tree visibility, with scenes containing trees yielding more positive evaluations compared to sound-only scenarios. Remarkably, the absence of trees in the roadside scene garners consistent evaluations across both experimental conditions. Significantly, higher roadside tree density in conjunction with the combined sound and VR video condition prompts a more favorable assessment than the sound-only scenario.DiscussionWhile the study indicates that roadside trees might not substantially mitigate perceived physical noise levels, their influence on the psychological well-being of urban inhabitants is considerable. The findings highlight that even though these trees may not overtly diminish noise, they hold substantial potential to enhance the overall comfort and well-being of city residents. This underscores the multifaceted benefits of integrating green spaces into urban design for improving the quality of urban soundscapes and residents’ experiences.

“…The study of the internal noise level in the bus with the hybrid-series configuration Volvo 7900 and the tram Konstal 105N HF was done at an inter-station distance between the stations Zawodzie Laczna and Zawodzie Petla, in Katowice (Poland). The range of emitted internal noise in the hybrid bus was between 54÷78 dB, while in the tram the range was in the range of 75÷85 dB [7]. Measurement of the level of external noise generated by city buses of standard length when the vehicle is in motion and when at rest, was done in the study Urban buses -Alternative powertrains for Europe.…”

Buses for public city transport in cities represent a significant source of noise, especially in the central city zones, on the traffic corridors with the highest hourly frequencies of public transport vehicles. The introduction of electric buses is one of the possible ways to reduce noise. The paper will present the results of the experimental measurement of noise levels of e-bus Higer KLQ6125GEV3 on the polygon, using the Lutron SL-4001 measuring instrument, following UN ECE 51.02 regulations and a comparison with the results of noise levels measurement with buses on diesel and CNG driveline.

The article presents an analysis of the possibility of using a smartphone for sound recording and analysis in relation to reference measurements carried out with laboratory equipment. The scope of the possibility of using recordings by non-calibrated noise measurement (smartphones) was presented, along with limitations and additional requirements that must be met so that such a measurement could be used for further analysis.
