In this research various objective quality measures are evaluated in order to predict the intelligibility for a wide range of non-linearly processed speech signals and speech degraded by additive noise. The obtained results are compared with the prediction results of a more advanced perceptual-based model proposed by Dau et al. and an objective intelligibility measure, namely the coherence spee...

INTRODUCTION  In recent years, the benefits associated with the use of cochlear implants (CIs), especially with regard to speech perception, have proven to surpass those produced by the use of hearing aids, making CIs a highly efficient resource for patients with severe/profound hearing loss. However, few studies so far have assessed the satisfaction of adult users of CIs. OBJECTIVE  To analy...

BACKGROUND Although cochlear implant (CI) users frequently report deterioration of sound quality when listening to music, few methods exist to quantify these subjective claims. OBJECTIVE 1) To design a novel research method for quantifying sound quality perception in CI users during music listening; 2) To validate this method by assessing one attribute of music perception, bass frequency perc...

Music plays an important role in the daily life of cochlear implant (CI) users, but electrical hearing and speech processing pose challenges for enjoying music. Studies of unilateral CI (UCI) users' music perception have found that these subjects have little difficulty recognizing tempo and rhythm but great difficulty with pitch, interval and melody. The present study is an initial step towards...

Human perception is a crucial factor in the evaluation and use of an application or artefact. Currently, there is a relevant number of websites that rely on collaborative tagging: such systems allow users to add tags (words) for categorising contents. In this work, we explored a methodology for detecting human perception by using collaborative tagging systems. This approach highlighted the pote...

OBJECTIVES To investigate the music perception skills of adult cochlear implant (CI) users in comparison with hearing aid (HA) users who have similar levels of hearing impairment. It was hypothesized that the HA users would perform better than the CI recipients on tests involving pitch, instrument, and melody perception, but similarly for rhythm perception. DESIGN Fifteen users of the Nucleus...

This study includes literature investigation on interactions and information perception of users in order to clarify interaction types for different contents. It turned out that information perception of users was in close relation with content types. UI factors for different contents and those for different interaction types were examined, and it turned out that UIs most frequently used for co...
