- Objective: The aim of the present study was to investigate how well the virtual psychophysical measures of spatial hearing from the preliminary auditory profile predict self-reported spatial-hearing abilities. Design: Virtual spatial-hearings tests (conducted unaided, via headphones) and a questionnaire were administered in five centres in Germany, the Netherlands, Sweden, and the UK. Correlations and stepwise linear regression models were calculated among a group of hearing-impaired listeners. Study sample: Thirty normal-hearing listeners aged 19–39 years, and 72 hearing-impaired listeners aged 22–91 years with a broad range of hearing losses, including asymmetrical and mixed hearing losses. Results: Several significant correlations (between 0.24 and 0.54) were found between results of virtual psychophysical spatial-hearing tests and self-reported localization abilities. Stepwise linear regression analyses showed that the minimum audible angle (MAA) test was a significant predictor for self-reported localization abilities (5% extra explained variance), and the spatial speech reception threshold (SRT) benefit test for self-reported listening to speech in spatial situations (6% extra explained variance). Conclusions: The MAA test and spatial SRT benefit test are indicative measures of everyday binaural functioning. The binaural SRT benefit test was not found to predict self-reported spatial-hearing abilities. Read More: http://informahealthcare.com/doi/abs/10.3109/14992027.2014.953216

- This paper describes a new approach to auditory diagnostics, which is one of the central themes of the EU-project HEARCOM. For this purpose we defined a so-called "Auditory Profile" that can be assessed for each individual listener using a standardized battery of audiological tests that - in addition to the pure-tone audiogram - focus on loudness perception, frequency resolution, temporal acuity, speech perception, binaural functioning, listening effort, subjective hearing abilities, and cognition. For the sake of testing time only summary tests are included from each of these areas, but the broad approach of characterizing auditory communication problems by means of standardized test is expected to have an added value above traditional testing in understanding the reasons for poor speech reception. The Auditory profile may also be relevant in the field of auditory rehabilitation and for design of acoustical environments. The results of an international 5-center study (in 4 countries and in 4 languages) will be presented and the relevance of a broad but well-standardized approach will be discussed.

D-2-6: Report about the results of the multicentre evaluation of the Auditory Profile. Public report

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Twenty-eight partners participated in the FP6 EU-funded project HearCom, with the goal to improve hearing in our communication society. One of the main achievements has been the provision of advanced hearing screening tests by telephone and Internet. For hearing diagnostics it was aimed at the harmonization of hearing diagnostic tests within Europe. For this the concept of the Auditory Profile has been developed with several tests for various languages. Hearing problems are also a result of adverse acoustical circumstances for which the effects have been studied, modelled and evaluated for hearing impaired. For hearing rehabilitation a large scale comparison study was performed on signal enhancement techniques (algorithms) for hearing devices. Modern technology may assist on hearing and communication by the use of wireless technology and automatic speech transcription. On this it is shown that improvements for auditory communication can be obtained, but that technology should develop further. An overview is given on the HearCom portal with sections for screening diagnostics, hearing information for the public and professionals, and a new service called HearCompanion that provides step-by-step support for the hearing rehabilitation process.
