This licentiate thesis contains experimental work about the use of binaural technology for assessment of sound quality.
Binaural technology aims to measure sound in the way compatible with human hearing.
For that purpose artificial head with the microphones in the position of the ears is used. First experiment aims at assessing sound quality of heavy-duty diesel engine which, runs on different fuels. The results show that engine running on different fuels possesses different sound quality characteristics. One of the purposes of binaural technology is to recreate sound field with correct spatial position of sound sources. However, the spatial position of sound sources is not always correctly recreated.
