Evaluating HRTF Similarity through Subjective Assessments: Factors that can Affect Judgment
نویسندگان
چکیده
This work investigates the associations between objectively measured distance metrics and subjective assessments of similarity in HRTF data. For this purpose two different means of matching users to HRTF sets were compared: a simple system computing correlations between personally collected HRTF data and a repository of 111 measured binaural datasets, and an HRTF user-preference study assessing the spatial quality of a subset of this data based on certain attributes. The purpose of this comparison is twofold: first, to investigate the presence of an association between HRTF distance and perceived spatial quality, and second, to identify factors that can affect subjective judgment. The results primarily highlighted the importance of binaural reproduction exposure and training for the appreciation and understanding of a virtual auditory scene. In addition, they offered a means of assessing the effectiveness of the utilized evaluation criteria as a function of user expertise.

The Use of Lexical Basis Functions to Characterize Faces, and to Measure Their Perceived Similarity
Over the last decade researchers have devised algorithms that can provide similarity measures between pairs of face images. These have been somewhat successful in estimating the similarities between face images under controlled conditions. However, those similarity measures do not parallel subjective similarity, as perceived by humans. In some applications it i s important to have a similarity ...
متن کاملAnalysis of the Spectral Variations in Repeated Head-related Transfer Function Measurements
This paper discusses the range of spectral variations between HRTF sets measured on the same subjects. The analysis is done in a corpus of 40 HRTF datasets of 4 subjects (10 datasets per subject). Variations are observed as a function of frequency, distance of the ears to the sound source (ipsilateral or contralateral), and location. Assessments of the spatial quality of all datasets were made ...

In the present study, in order to explain the desirability of the soundscapes of the Timchehs of Tabriz Bazaar, Sound Pressure Level (SPL) and Reverberation Time (RT) have been measured as objective variables of acoustic behavior. Using descriptive questionnaire, subjective assessments were used to determine the quality of soundscape. The research seeks to answer the question of how the spatial...
متن کاملEffective and efficient subjective testing of texture similarity metrics.
The development and testing of objective texture similarity metrics that agree with human judgments of texture similarity require, in general, extensive subjective tests. The effectiveness and efficiency of such tests depend on a careful analysis of the abilities of human perception and the application requirements. The focus of this paper is on defining performance requirements and testing pro...
متن کاملCognitive Factors Affecting Subjective Probability Assessment
Prior probabilities are central to Bayesian statistics. The Bayesian paradigm assumes that people can express uncertainty in terms of subjective probability distributions. This article will consider Hogarth's 1975 assessment that \man is a selective, sequential information processing system with limited capacity,. .. ill-suited for assessing probability distributions." Particular attention will...
