Soundscape reproduction using headphones for web-based listening test
* Presenting author
One of the methods to analyse a soundscape is by reproducing the soundscape. The acoustic environment reproduction usually conducted using multi-speaker systems in a laboratory. The experiment usually conducted individually resulting limited respondent of the experiment. A web-based experiment is one of the alternatives to do the soundscape study. By using the internet, the experiment can be done easier with more respondents. The experiment using the internet usually conducted using an online questionnaire which can play a stereo sound or a video. In this study we are testing the validity of XY, Mid-Side, and Head Tracking decoders to reproduce acoustic environments using headphones. The XY and Mid-Side decoders were used to decodes B-Format signals to stereo signal which can be played directly by the online questionnaire. The head tracking system is used to represent the experiment done using Youtube 360 of Facebook 360.Analysis based on semantic score indicates that the listening test conducted using stereo decoders can gives the similar score with the listening test conducted using ambisonic reproduction system. Further analysis using semantic differential analysis shows that the experiment conducted using Mid-Side decoders can deliver the same soundscape dimensions with the in-situ experiment.
