Subjective Evaluation of Soundscape Recordings in the Psychoacoustic Experiment

Soundscape is a term that describes a paradigm that shifts its focus from the harmful sound effects on humans (noise) to the full experience of sound in which people live in. Soundscape thus refers to a variety of sound sources that create the whole sound field. For soundscape description the psychoacoustic experiments are needed, in which subjects in different ways evaluate some of its aspects. In this experiment it was required that the subjects were presented with realistic sounds and therefore binaural technique was used. This paper gives a short description of the experiment preparations: recording with binaural microphones and equalization of headphones transfer functions with minimum phase filters. Moreover, the results of the psychoacoustic experiment, conducted at the University of Zagreb, Faculty of Electrical Engineering and Computing, are given in the paper. In the experiment subjects evaluated on three semantic differential scales the subjective parameters of sounds recorded in different locations: Zagreb and Varaždin in Croatia, and in Malta. During the evaluation of soundscape parameters, subjects listened to recordings with two different levels of signal-to-noise ratio. By comparing the obtained values, the effect of noise in the recordings on the credibility of results will be determined.
