’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: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...

Im Focus: How to inflate a hardened concrete shell with a weight of 80 t

At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).

Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...

Im Focus: Bacterial Pac Man molecule snaps at sugar

Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...

Im Focus: Repairing defects in fiber-reinforced plastics more efficiently

Fiber-reinforced plastics (FRP) are frequently used in the aeronautic and automobile industry. However, the repair of workpieces made of these composite materials is often less profitable than exchanging the part. In order to increase the lifetime of FRP parts and to make them more eco-efficient, the Laser Zentrum Hannover e.V. (LZH) and the Apodius GmbH want to combine a new measuring device for fiber layer orientation with an innovative laser-based repair process.

Defects in FRP pieces may be production or operation-related. Whether or not repair is cost-effective depends on the geometry of the defective area, the tools...
