Bringing 3D models to life acoustically

06.04.2017

At Hannover Messe, taking place April 24 – 28, Fraunhofer IDMT will be presenting the findings from a research project on making the sounds of electrically powered machines, devices, or components audible during virtual product development already. New developments allow the use of 3D models to analyze, assess and improve the acoustic properties of products, instead of building costly real prototypes.

What do heavy production machinery, such as milling machines or CNC cutting machines, and household appliances, like washing machines or hair dryers, have in common? Not very much, one might suppose imagining the visual characteristics of these different objects only. But if we extend our imagination to hearing, we will find that all these objects produce specific sounds. Sound plays an increasingly important role in the marketing of products.


Bringing virtual products and machines to life acoustically is the goal of Fraunhofer IDMT´s research.

During the buying decision process, customers and consumers increasingly base their subjective assessment of a certain product on its acoustic properties – while some sounds are perceived as pleasant, conveying the impression of robustness and reliability, others are considered as unpleasant, promoting a feeling of untrustworthiness and uncertainty. So what a product sounds like when we are using it really matters.

“Nowadays, in virtual product development, it is possible to simulate and assess all kinds of properties and characteristics of the product to be developed, except for the product’s acoustic properties”, says Dr. Sandra Brix, manager of the research project entitled “AVP3 – Acoustically Advanced Virtualization of Products and Production Processes”.

“Our goal is to auralize virtual product models, which basically means that we want to make 3D models audible”. Building on its broad scientific expertise in the field of spatial sound reproduction using wave field synthesis, Fraunhofer IDMT is currently working on methods and techniques to link the 3D visualization of prototypes with the respective authentic sounds.

This is done by computing the sound signals produced by a machine or device with the help of acoustic models, before the signals are made audible using the technology of SpatialSound Wave, Fraunhofer IDMT’s system for producing and replaying three-dimensional sound.

A special challenge lies in the correct simulation of the acoustics of virtual prototypes taking into account different perspectives from which they are viewed and, consequently, heard. “The sound of a virtual object must be as realistic as possible in order to be able to correctly assess its acoustic properties and behavior from any direction”, says Sandra Brix.

Joining Fraunhofer IDMT in the AVP3 project, which is funded by the German Federal Ministry for Economic Affairs and Energy, are two universities and five enterprises.

If you are interested in 3D visualization and auralization being linked for the first time, please feel free to visit us at the Fraunhofer booth C22, hall 2.

Im Focus: Data storage using individual molecules

Researchers from the University of Basel have reported a new method that allows the physical state of just a few atoms or molecules within a network to be controlled. It is based on the spontaneous self-organization of molecules into extensive networks with pores about one nanometer in size. In the journal ‘small’, the physicists reported on their investigations, which could be of particular importance for the development of new storage devices.

Around the world, researchers are attempting to shrink data storage devices to achieve as large a storage capacity in as small a space as possible. In almost...

Im Focus: Data use draining your battery? Tiny device to speed up memory while also saving power

The more objects we make "smart," from watches to entire buildings, the greater the need for these devices to store and retrieve massive amounts of data quickly without consuming too much power.

Millions of new memory cells could be part of a computer chip and provide that speed and energy savings, thanks to the discovery of a previously unobserved...

Im Focus: An energy-efficient way to stay warm: Sew high-tech heating patches to your clothes

Personal patches could reduce energy waste in buildings, Rutgers-led study says

What if, instead of turning up the thermostat, you could warm up with high-tech, flexible patches sewn into your clothes - while significantly reducing your...

Im Focus: Lethal combination: Drug cocktail turns off the juice to cancer cells

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.

The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...

Im Focus: New Foldable Drone Flies through Narrow Holes in Rescue Missions

A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.

Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
