A selection of sounds, developed by academic researchers, are being tested as part of a project to increase pedestrian awareness of e-scooters without contributing to noise pollution.
The first of its kind tests are being conducted by the University of Salford, in partnership with the Royal National Institute for Blind People (RNIB) and micromobility company Dott.
Wearing a virtual reality headset, participants are immersed into a 360-degree environment, featuring simulations of e-scooter riders in different scenarios.
The group of participants, including blind and partially sighted, will be asked to identify when they are first aware of the e-scooter and provide feedback on the suitability and preference of the three sounds.
The tests will take place in a laboratory in London, before being repeated in Italy, Sweden and Spain in collaboration with blind associations across Europe.
The trials in different countries are designed to ensure international relevance with the aim of creating a global standard for an e-scooter sound.
Dr Antonio J Torija Martinez, principal investigator, University of Salford, said: “We are testing a series of carefully designed e-scooter sounds to find the right balance between maximum vehicle noticeability and minimum noise pollution.
“Using virtual reality to create immersive and realistic scenarios in a safe and controlled laboratory environment will allow us to achieve robust results.
“By working closely with the RNIB and blind associations across Europe, we can ensure that the sound we develop is the best fit for their needs.”
Robin Spinks, RNIB head of inclusive design, said: “Light electric vehicles emit virtually no sound. Imagine for a second how terrifying this could be if they are used irresponsibly for someone with little or no sight.
“We’re working with multiple stakeholders across the transport industry to bring about sustainable improvements in safety, perceivability and awareness.
“Operators, researchers, and regulators must all collaborate to ensure a more inclusive urban environment for all.”
Following the virtual reality phase, the sounds will be tested on the streets of London and across Europe, to validate the laboratory setting findings.
I am elderly and have a severe mobility impairment. I use crutches to get around. Precisely what am I, and the many others like me, expected to do when we hear the sound of an e-scooter approaching – usually on the pavement? Leap out of the way?? And what about deaf and hearing impaired pedestrians who cannot hear these sounds??
This ridiculous idea of adding sounds to e-scooters is certainly not supported by all blind organizations across Europe; some are campaigning against it and against e-scooters in general as the horrendous deaths and injuries (physical and mental) to pedestrians and animals increase.
