Crowdsourcing listening tests using an audio polling station
As an alternative to laboratory controlled listening tests, a crowd sourced approach was tested using an audio polling station installed in a sound-related exhibition. Among other subjects, visitors were asked to provide their opinion concerning sound quality of vehicles and sound quality of audio coding algorithms. Using the same data set, another series of evaluation results were obtained in laboratory conditions with a limited number of participants. With partially uncontrolled conditions and a larger number of participants, the results obtained using the audio polling station are in line with laboratory results.
