... The influence of noise sources other than tyre/road is eliminated at most driving speeds. Also, this measurement method has been shown to be suitable for annoyance studies [37]. Moreover, since the source of tyre/road noise is in close proximity to the tyre/road interface, a substantial part of the propagation effect by acoustically absorptive surfaces is included in the microphone signal. ...

Tyre/Road Noise Annoyance Assessment Through Virtual Sounds

... Unlike other physical factors, people perceive noise by a specific auditory system. Thus, it is a phenomenon everyone perceives and evaluates, which is why noise exposure is one of the most common, if not the most frequent, complaints of residents living in large cities [3], [4]. Traffic is the most frequently cited noise source in these cities and their surroundings [5]. ...

... Similarly, the present local oscillations produce by central pattern generator can generate ERD modulation during motion observation. A recent study performed with patient with lesion to the form visual pathways also agrees with the idea that form cues are not critical for biological motion perception (Gilaie-Dotan et al., 2015) and that observer can still discriminate locomotion direction or identify living being from spatially scrambled displays that contain solely local biological motion cues (Sumi, 1984;Pavlova, 1989;Chang and Troje, 2008). Nonetheless, beta 1 band suppression in fronto-parietal areas was stronger when the stimulus displayed a coherent body structure compared to the scrambled version suggesting that human body geometry improves the sensorimotor integration of the visual input. ...

... Additionally, researchers have shown that the human auditory system is capable of 'learning' foreign HRTFs by the help of dedicated training sessions. Studies found that localisation accuracies, using different HRTFs, improved not only for the trained positions but also for others, allowing them to conclude that trained localisation abilities can be generalised to untrained auditory positions (Mendonça et al., 2012a). A follow-up study by the same team of authors focused on the longitudinal effects of training, in which pre-training localisation errors were compared to post-training errors immediately after training, one week later and one month later. ...

... A follow-up study by the same team of authors focused on the longitudinal effects of training, in which pre-training localisation errors were compared to post-training errors immediately after training, one week later and one month later. Results showed the lasting effects of training sessions, as participants were able to retain higher accuracies even a month after the initial test (Mendonça et al., 2012b). ...

... These findings indicate that using auralisation with non-individualised HRTF should always be preceded by a learning period. This work, on the basis of an earlier presentation at the 129 th AES Convention, was selected for publication in the AES Journal [15]. ...

... Speed limit reductions and quieter road surfaces not only reduce overall noise emissions but also change the spectral and psychoacoustic characteristics of tyre/road noise (Barros et al., 2023), which are closely related to the human auditory perception (Altinsoy, 2022). This effect has been confirmed via laboratory-based listening tests, where traffic noise from higher speeds or uneven surfaces caused significantly more annoyance than expected given the overall differences in noise levels only (Freitas et al., 2012;Fiebig & Jakobs, 2022). ...

... Apart from the previously mentioned NHTSA-issued research, several other studies found that slowly driving EVs are often harder to detect than ICEVs (Mendonça et al., 2013), adding warning sounds can increase detection probability (Parizet et al., 2014;Roan et al., 2021) and help with estimating the trajectory of accelerating vehicles (Wessels et al., 2022), synthetic sounds can be more efficient in terms of detection than ICE sounds (Poveda-Mart ınez et al., 2017), a velocity-dependent pitch shift and amplitude modulation may benefit detectability (Fleury et al., 2016;Emerson et al., 2013), and experiments performed in virtual environments can predict real-world EV detection (Singh et al., 2015). However, most of these studies are limited to evaluating the detection of single vehicles. ...
