Silent Green Researching quieter and cleaner refuse collection
In order to conserve resources and at the same time improve the quality of life and air quality for the people in Frankfurt, the Frankfurt Disposal and Service GmbH (FES) and the Frankfurt University of Applied Sciences (Frankfurt UAS) are setting out together, supported by the state of Hesse, they are testing the potential of a refuse collection vehicle with a new natural gas-electric hybrid drive. For the first time, exhaust emissions of diesel-powered refuse collection vehicles are measured during operation. Additionally, the noise emissions are determined.
The accurate placement and orientation of microphones around an object can often be complex and tedious. This has previously been solved either by setting up elaborate auxiliary structures or by relying on visual judgement which can be problematic, especially for hand-held measurements. Augmented reality represents an innovative approach to this problem, by using additional information made available to a user wearing a head mounted display, auxiliary structures are no longer required for accurate positioning of the microphones, as virtual guides visible only to the user can be used instead. This method greatly improves the efficiency of the entire measurement, and also increases the quality of the results by eliminating sound field influencing objects.
Using a model of the refuse collection vehicle, visitors are given the opportunity to view the emissions by entering the virtual world via an AR-headset.
