Acoustic comfort is one of the important topics in terms of user satisfaction. In order to determine and control acoustic comfort, measurable parameters are needed to be able to compare and improve soundscapes. Parameters for architectural acoustics, like reverberation time and sound pressure level are widely used for this purpose. Psychoacoustic parameters like loudness, sharpness, roughness and fluctuation strength are mostly used for determining the sound quality of mechanical sounds. They have also started to be used for evaluating soundscapes of open areas and enclosed spaces. This research aims to find out the relationship between the psychoacoustic parameters and acoustic comfort in non-acoustic enclosed public spaces, specifically in eating establishments. To reach this aim, both on-site measurements and in laboratory listening tests were conducted in five eating establishments. During on-site measurements, a simultaneous questionnaire study was also conducted. Subjective and objective data were comparatively evaluated. Listening tests were based on auralizations with calibrated simulation models. This provided a research model, that allows control over the acoustic environment without having to make real changes in the physical elements of the eating establishments. The auralization sound files were presented to listening test participants with headphones and they evaluated soundscapes with different psychoacoustic properties. The last chapter provides a summary of results and suggestions for future studies. Better acoustic comfort was found to be related with higher sharpness, lower reverberation time, lower loudness and lower roughness values for the examined parameter ranges.
