’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.”

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
