’Sound icons’ to warn drivers of hazards

24.03.2004


Researchers have subjected volunteers to the sounds of cockerels, bells, babies crying and footsteps to find out how people perceive urgency and pleasantness.



The two-year EPSRC-funded project aims to find the most appropriate sounds – such as those of screeching tyres or car horns – to warn drivers of hazards on the road.

Researchers from the school of psychology are helping car manufacturers come up with the best ‘audible icons’ to convey alerts to drivers by discovering the appropriateness of different sounds.


In their tests the most unpleasant sound was found to be a horn blast and the least unpleasant the sea. The most urgent was an electronic warning pulse and least urgent the sound of a house martin singing. Highly urgent sounds were also judged least pleasant.

Car manufacturers are interested in the use of ‘realistic’ sounds as alerts because they cut reaction times and increase drivers’ awareness of what is going on around them.

Sounds do not interfere with the visual aspects of driving the car and reaction time is cut if meaningful sounds are made to indicate a specific hazard rather than simply indicating that something is amiss.

Over the next year Leeds researchers aim to find out exactly which types of sounds are most suitable as audible icons in cars using the University’s advanced driving simulator. The research is necessary to ensure that a sound is perceived as having a meaning but is not so annoying that car users disable it.

Dr Denis McKeown, who is leading the project, said the use of audible icons would be particularly useful for collision detection systems being developed by car makers. These use sensors to measure the speed and distance of a vehicle from the car in front and regulate braking so the two do not collide.

He said: “Audible icons may produce significantly faster response times than tone or speech warnings but we have to find out which ones convey the right degree of urgency and a commonly-understood meaning. While using such ‘realistic’ sounds as alarms conveys more meaning there is a possibility people can respond incorrectly and not take enough time to assess the road situation themselves.”

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.

Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
