“…Adhering to the International Standard Organization (ISO R 362), 19 the authors measured these parameters to be considered for the generation of traffic noise models, which are the speed of vehicles and the height of measurement from ground level. They noted that perception from the noise source to receiver differs.…”

Traffic noise is a major cause of noise pollution, and impacts of noise pollution on humans have been studied extensively. Previous studies have helped in the development of traffic noise prediction analysis using robust analytical and computational models, parameters connected with traffic, road characteristics, and environment. This study reviewed 11 traffic noise modeling strategies and parameters used by various agencies in different parts of the world. Seven out of the 11 models reviewed in this paper were based on outdoor measurements while the remaining four were based on outdoor and indoor measurements. Considering the cost and time involved in developing these models, there is need to understand existing traffic noise models, differences, and assumptions before adopting or recalibrating them for local demands. This study contributes to the larger body of knowledge and intends to serve as a reference material for future researchers in the area of traffic noise modeling and techniques.

“…The directivity of a sound source is one of the parameters that must be considered to determine the effect of noise over a potential receiver, for instance, on traffic noise prediction models [27]. Some measurement techniques can be found on the literature to determine this parameter: stationary vehicle directivity [28]; moving sources [29]; vertical directivity for moving sources (trains [30,31,32], aircraft [33,34], road vehicles [35]); horizontal directivity of road vehicles [36]. In order to determine the radiation pattern of the vehicles, the use of a linear microphone array during pass-by tests may be appropriate to detect the position and speed of the moving noise source [37] and therefore, to obtain the sound pressure level (SPL) for each angle suppressing background noise.…”

Since motorcycles are one of the main sources of noise in urban environments, the use of electric powered two-wheelers may contribute to the improvement of soundscapes in Smart Cities. However, quiet vehicles can lead to an increased risk of accident for pedestrians and other drivers. In order to assess the noise generated by powered two-wheelers and their detectability, five different low capacity motorcycles were measured in a pass-by noise test. The measurements were performed at different speeds using a linear microphone array and a dummy head. The sound directivity radiated by the moving sources was studied with a microphone array. To establish the detectability of powered two-wheelers, thirty-seven subjects participated in an auditory test consisting on a virtual road-crossing scenario. The subjects had to detect the approaching of a vehicle at 20 km/h. The results showed a significant reduction in the sound pressure level emitted by electric motorcycles at low-speed, as well as a notable increase in sound directivity with velocity. The reaction time obtained for the detection of electric powered two-wheelers was higher compared to the traditional propulsion ones. The results highlighted the risk posed by this kind of electric vehicles for pedestrians.
