Sounds affect us. And they have a greater impact than previously thought. But what is good acoustic quality? In a new project, researchers will develop a model that makes it possible to predict how sound waves behave and affect people in urban spaces. (Photo: Colourbox)

Less noise in large cities

A good sound environment promotes well-being and health. Researchers will now study the way noise behaves in urban space, and come up with new standards for acoustic quality.

Walk through your building before it has been built

A special 3D cinema has opened at Aarhus University. It makes it possible to experience a building both inside and out while it is still on the drawing board.

The underwater robot DeepFreeze has provided polar researchers with very detailed knowledge about ice algae, which are the key to understanding life in the Antarctic waters. Pictured here are Tor Dam Eskildsen and Thomas Juul, who designed and built the robot for the researchers. (Photo: Tor Dam Eskildsen)
The robot enters the water through a hole in the ice. It is made of a material that can withstand considerable temperature fluctuations and protect the electronics in cold underwater conditions. It is steered from the surface by a standard X-box controller. (Photo: Tor Dam Eskildsen)
Good data quality depends on the robot being able to take measurements at exactly the same places under the ice over time. So what do you do when the ice is too thick for the GPS signals to penetrate? DeepFreeze is equipped with digital cameras that look through the cold, clear water towards two light sticks in the ice. The information is then sent to a computer that calculates the number of pixels between the two sticks and thereby the exact position of the robot. (Photo: Tor Dam Eskildsen)

Underwater robot provides new opportunities for polar research

Two engineering students have built an underwater robot that can analyse algae conditions under the Antarctic sea ice. This provides completely new opportunities for polar research, and the robot has just successfully completed its first scientific expedition to Greenland.

A new team of engineering students is competing in the Shell Eco-marathon 2016. In the coming months, they will finish off AU2, possibly the most energy-efficient vehicle in the world. (Photo: Team AU)

Team AU ready for the Shell Eco-marathon

The countdown has begun for this year’s world championship in ultra-energy-efficient vehicles. After two years of intensive development work, Aarhus University (AU) will now enter an ultra-efficient eco-car in the Shell Eco-marathon, which kicks off in London in June. The aim is to drive almost 9000 kilometres on the equivalent energy of one litre…

A single calculation can result in up to several thousand different combinations of wrong answers. Engineering students are behind a new app that can spot what a child has done wrong in less than a second. (Photo: Red Raccoon)
The new mathematics app is based on many hours of user tests. Pictured here are Casper Kjeldsen and Jakob Halling visiting a private school in Aarhus. (Photo: Red Raccoon)

New app teaches children to count correctly

A new mathematics app is a hit in Denmark. It spots children’s weak points when they are doing mathematical exercises and explains where they are going wrong.

Curved buildings are difficult. They require advanced supporting structures and expensive facade solutions. Or do they? This tower could be the first step on the way to more shapes in the building industry of the future. Two engineering students have built a 10-metre-high tower made of fibreglass-reinforced concrete. And it can support itself. (Photo: AU Engineering archive)

Students construct self-supporting tower

Two engineering students have worked out how to make curved buildings using facade plates with no other supporting structure. This can bring the building industry closer to shapes that have previously been impossible.

In the coming years, researchers will gain new knowledge about how to integrate gas into the Danish energy system. Pictured here is Associate Professor Lars Ditlev Mørck Ottosen, Department of Engineering (Photo: Lars Kruse)

More green gas on the way

In the coming years, Aarhus University will contribute with new knowledge about how to ensure better integration of gas in Denmark’s energy supply for the benefit of the climate. Innovation Fund Denmark is investing DKK 18.6 million in the project.

More stairs and not so many elevators. Researchers have been busy measuring and carrying out fieldwork among the residents of a 12-storey building to study the extent to which it is possible to change energy behaviour with the help of simple information. (Photo: Hasle Photo)
The elevator experiment is part of the Virtual Power Plant project. Here researchers are working to design intelligent buildings that automatically respond in the most sustainable way to the power requirements of consumers. Pictured here is Rune Hylsberg Jacobsen. (Photo: Anders Trærup)

Simple technology makes elevators ‘green’

Having a guilty conscience about the climate makes us choose to take the stairs instead of the energy-devouring elevator – at least to a certain extent. This is the conclusion of a research project involving almost 200 residents in a 12-storey building in Aarhus.

What do you do with outdated wind turbine blades and aircraft made of expensive fibreglass? You cut them up into pieces and bury them in the ground. Or possibly in the future, you add a chemical substance that can separate the glass from the plastic fibres so they can be recycled. This is the common goal for researchers and companies in Innovation Fund Denmark’s new project called DreamWind. (Photo: Vestas archives)
There will be plenty of activity in the laboratories in the coming years when researchers develop new materials that make recycling easier. Pictured here is Associate Professor Mogens Hinge, Department of Engineering. (Photo: Anders Trærup)

Wind turbine blades of the future will be recyclable

In the DreamWind project, researchers will develop a chemical substance that will make it possible to separate composite materials from each other. This means that the large and expensive fibreglass components from wind turbines will be recyclable in the future.

Using advanced signal treatment, researchers can now divide a room into sound zones that do not disturb each other. In the coming three years, they will collaborate with the Chinese acoustic company GoerTek Inc. They will develop the technology so it can be commercialised and thereby moved out of the laboratory and into our living rooms.

Sound zones on the way to the living room

Aarhus University has entered into a collaborative agreement with one of the world’s major manufacturers of speakers. The aim is to fully develop a new technology that can make it possible to divide our homes into sound zones.
