Dear Frederico,
I will be starting a project with the National Disability Authority in Ireland quite soon in a similar area, specifically concerning speeds
20km/h and below. We will also want to compare IC engine sounds (across reasonable vehicle-age ranges as Leonardo correctly points out) and AVAS in EVs. Our primary reference point has been ISO 16254 and several other indirectly related standards (e.g. ISO
362), and subsequent regs like UNECE Reg 138 and Regulation (EU) No 540/2014.
The literature is quite sparse on the ground in relation to perceptual evaluations of these sound signatures. Given the speed cap in our project,
tyre-on-road will be less of a factor for us and our research will focus on urban centres rather than highways.
Ultimately, we are going to have to build the datasets for our project. One of our preliminary tasks for this is how we structure these data
and corresponding metadata, as there’s more to this than just the acoustic signature itself. We intend on hosting these datasets on a Irish national pilot platform based on EUDAT services, called IRLDAT.
Feel free to send me an email to link up.
Leonardo: very interesting information and papers – thanks for sharing.
Le gach dea-ghuí / Best wishes,
Flaithrí.

Dear Auditory List,
I hope this message finds you well.
I am currently in search of published research pertaining to the discrimination of electric vehicles compared to internal combustion vehicles based on noise emissions. Specifically, I am interested in studies
that explore the feasibility of implementing such discrimination systems in highway environments (such as installed in span structures, toll plazas, etc..).
I acknowledge inherent challenges associated with this task, including issues related to extraneous noise, the utilization of Acoustic Vehicle Alerting Systems (AVAS), and, notably(?), the dominance of tire-road
noise at higher velocities. My particular interest lies in uncovering research that delves into specific acoustic features that may be extracted from microphone array beamforming systems.
From searches on Google Scholar, I was unable to find substantial literature on this specific topic. Therefore, I am reaching out to the esteemed members of this community to inquire if any of you could direct
me towards relevant literature addressing this topic.
Thank you in advance for your assistance.
