Özet:

Auditory distance perception is a multidimensional phenomenon. Familiarity with the sound source is known to have an important effect on the distance perception as one of the cognitive cues. An auditory distance perception experiment to assess the effects of interpersonal familiarity on auditory distance perception is reported in this article. The subjective experiment involves a binaural listening experiment where different source distances between 0.5 and 16 meters were simulated. The participants are 12 heterosexual couples who have known each other for at least two years with daily interaction. All couples were strangers to other participated couples. Each subject listened and judged the distance of five different speech utterances from their partner (F0), the spectrally most similar stranger (F1) and the spectrally most dissimilar stranger (F2). The results indicate that there is no significant effect of interpersonal familiarity on auditory distance perception for the three conditions of familiarity. For further investigation, results revealed another interesting point that other cognitive factors besides the interpersonal familiarity (e.g. semantic aspects of the utterances listened) could be as useful as acoustic cues on the enhancement of auditory distance perception
