Konferensbidrag (refereegranskat)abstract
- In an experiment, inspired by aspects of the Repertory Grid Technique, to find the dimensions forming the perceived spatial impression of a sound reproducing system, subjects frequently described their experiences as being either natural or artificial. These results are analyzed using multivariate methods to investigate the correlation between attributes relating to naturalness and other more descriptive attributes.

- When assessing the spatial performance of sound reproducing systems, various research methods from the fields of psychology and the behavioural sciences may be considered. Selected approaches are briefly reviewed, with particular emphasis on the Repertory Grid Technique (RGT). Further analysis of a pilot experiment relating to spatial parameters, inspired by RGT, is described

Tidskriftsartikel (refereegranskat)abstract
- The evaluation of the perceived spatial quality of an audio system has become more important as the technical possibilities to render spatial information increase. In recent years the field of spatial quality evaluation has been the subject of more thorough investigations than previously, one of the problems being the development of attribute scales appropriate for this purpose. The generation of attributes of spatial audio by means of elements from the repertory grid technique is investigated. In an experiment personal constructs in the form of verbal descriptors were elicited. The constructs were classified by verbal protocol analysis and reduced to a limited number of attributes by cluster analysis. The results show that the repertory grid technique enables a number of attributes of spatial sound quality to be extracted from a group of subjects and that these attributes correspond well with attributes found in other studies. The results also indicate the importance of a definition of the part-the whole or a subset-of the auditory scene to which a specific attribute is referring.

Konferensbidrag (refereegranskat)abstract
- When assessing the spatial performance of a sound reproducing system, knowledge of the dimensions forming the perceived spatial impression is important. In this search, methods from the behavioral sciences have to be considered. This paper describes an analysis of an earlier experiment, inspired by aspects of the Repertory Grid Technique, which focuses on finding common patterns among a group of subjects.

Systematic evaluation of perceived spatial quality

Konferensbidrag (refereegranskat)abstract
- The evaluation of perceived spatial quality calls for a method that is sensitive for changes in the constituent dimensions of that quality. In order to devise a method accounting for these changes, several processes have to be performed. This paper shows the development of scales by elicitation and structuring of verbal data, followed by validation of the resulting attribute scales.

Validity of Selected Spatial Attributes in the Evaluation of 5-channel Microphone Techniques

Ingår i: 112th AES Convention. - : Audio Engineering Society, Inc..

Konferensbidrag (refereegranskat)abstract
- Assessment of the spatial quality of reproduced sound is becoming more important as the number of techniques and systems affecting such quality increases. The presence of dimensions forming spatial quality has been indicated in earlier experiments by using attributes as descriptors for the dimensions. These attributes have been found relevant for describing the spatial quality of stimuli subjected to different modes of reproduction. In this paper, new attributes are elicited and the applicability of these and previously encountered attributes for assessment of spatial quality is tested in the context of new stimuli, recorded by means of 5-channel microphone techniques and reproduced through a 5.0 system.

Verification and correlation of attributes used for describing the spatial quality of reproduced sound

-
Konferensbidrag (refereegranskat)abstract
- When the spatial quality of reproduced sound is to be assessed, knowledge of the dimensions forming the quality is essential since the quality is known to be multi-dimensional. The dimensions could be indicated by attributes describing them. Attributes encountered during a previous experiment are considered by a group of subjects and their responses are analysed for finding the attributes' applicability and dimensionality over an extended number of sound stimuli.
