Abstract:
To evaluate surrounding sounds, it is best to experience them wherever they occur. However, in many cases it is not feasible to run experiments in the field. Certain sounds may occur only rarely, under certain conditions. With the immersive media lab at the institute of communications technology, we have the possibility to reproduce recordings realistically.In the past years investigations on noise perception were conducted exemplary on wind turbine sounds.The investigations did not focus on gaining new insights on the noise source, but rather how to present it to participants in the laboratory.The first investigation was on the audio reproduction, the second on the visual presentation.Another study was made on the reproducibility of a laboratory study online.Our results show that it is important for participants to get a proper idea on the context of the scenarios to evaluate. Thus, a visual representation proved to be very helpful. In terms of immersion, a 360° video scores higher than a cave-like projection. In terms of audio, sound field reproduction was subjectively favoured. An online study can be helpful for obtaining first trends for further investigations.
