Background:<\/p>\n\n\n\n
Laboratory tests are frequently used to quantify the benefit of hearing devices and their specific features. However, several studies have demonstrated that these tests often do not predict how beneficial the devices\/features are to users in their everyday listening situations (e.g. Bentler et al., 1993; Walden et al., 2000; Cord et al., 2004; Cord et al., 2007). The discrepancy in outcomes measured in the laboratory and in the field is likely due to the lack of several relevant variables from current laboratory tests (Jerger, 2009), including dynamic variations in spatial and level characteristics of the acoustic environment, the presence of reverberation, and co-ordinated visual information. In addition, conventional speech tests mainly require verbatim repetition of what was heard (auditory processing), while interactive communication also requires that meaning is extracted from what was heard and a response formulated, skills that further depends on cognitive processing, attention, memory, and language (Pichora-Fuller and Singh, 2006). There is thus a need for new kinds of laboratory tests that better represent real-world listening and communication situations to provide more accurate predictions of a person\u2019s ability to engage in conversations. Such tests would produce more ecologically valid outcomes of the potential real-life benefit from a hearing device and enable researchers and developers to optimise new features earlier by bypassing lengthy field trials. Better prediction of the real-life outcome with a hearing device before its commercial release would further assist clinicians and hearing device users in developing more realistic expectations of its effect on communication ability, ultimately resulting in increased success and satisfaction with amplification.<\/p>\n\n\n\n
Objectives:<\/p>\n\n\n\n
Creation of a database of critical real-world acoustic (and visual) environments that can be played back via different loudspeaker systems and that can be reliably used for hearing instrument development and evaluation.<\/p>\n\n\n\n
2. Obtain a better understanding of the effects of introducing relevant variations to stimuli and test methods -> Development of new tests that better engage real-world mental and cognitive processes.<\/p>\n\n\n\n
