To investigate the influence of an algorithm designed to enhance or magnify interaural difference cues on speech signals in noisy, spatially complex conditions using both technical and perceptual measurements. To also investigate the combination[...]Article
Florian Denk, Auteur ; Marko Hiipakka, Auteur ; Birger Kollmeier, Auteur ; Stephan M. A. Ernst, Auteur |An important and often still unresolved problem of hearing devices such as assistive listening devices and hearing aids is limited user acceptance – a primary reason is poor conservation quality of the acoustic environment. Approaching a possibl[...]Article
Binaural cues such as interaural level differences (ILDs) are used to organise auditory perception and to segregate sound sources in complex acoustical environments. In bilaterally fitted hearing aids, dynamic-range compression operating indepen[...]Article
Rainer Huber ; Thomas Bisitz ; Timo Gerkmann ; Jurgen Kiessling ; Hartmut Meister ; Birger Kollmeier |The perceived qualities of nine different single-microphone noise reduction (SMNR) algorithms were to be evaluated and compared in subjective listening tests with normal hearing and hearing impaired (HI) listeners. Design: Speech samples added w[...]Article
Tahereh Afghah, Auteur ; Julia Schütze, Auteur ; Markus Meis, Auteur ; Birger Kollmeier, Auteur ; Kirsten C. Wagener, Auteur |Objective The International Classification of Functioning Disability and Health (ICF) is a classification of health and health-related domains created by the World Health Organization and can be used as a standard to evaluate the health and dis[...]Article
Steffen Kortlang ; Zhangli Chen ; Timo Gerkmann ; Birger Kollmeier ; Volker Hohmann ; Stephan D. Ewert |Single-channel noise reduction (SCNR) and dynamic range compression (DRC) are important elements in hearing aids. Only relatively few studies have addressed interaction effects and typically used real hearing aids with limited knowledge about th[...]Article
Jonathan Albert Gösswein, Auteur ; Jan Rennies, Auteur ; Rainer Huber, Auteur ; Tobias Bruns, Auteur ; Andrea Hildebrandt, Auteur ; Birger Kollmeier, Auteur |Objective This study investigated the effects of different adjustment criteria and sound scenes on self-adjusted hearing-aid gain settings. Self-adjusted settings were evaluated for speech recognition in noise, perceived listening effort, and p[...]Article
Objective: This paper describes the composition and international multi-centre evaluation of a battery of tests termed the preliminary auditory profile. It includes measures of loudness perception, listening effort, speech perception, spectral a[...]Article
A review about technical and perceptual factors in hearing aid technology, research and development is provided, covering current commercial solutions, underlying models of hearing loss for usage in hearing devices and emerging future technical [...]Article
A generalised concept for hearing aid fitting and fine-tuning based on estimated individual traits is presented along first implementations in this report. Design: To estimate the individual traits, a set of auditory model-based performance meas[...]Article
Objective: Auditory steady state responses have been suggested for simultaneous threshold assessment using the multiple ASSR (MASSR) technique. However, at least at high stimulation levels, strong interactions reduce response amplitudes. The pre[...]Article
Christoph Volker ; Thomas Bisitz ; Rainer Huber ; Birger Kollmeier ; Stephan M. A. Ernst, Auteur |Two modifications of the standardised MUlti Stimulus test with Hidden Reference and Anchor (MUSHRA), namely MUSHRA simple and MUSHRA drag&drop, were implemented and evaluated together with the original test method. The modifications were designe[...]Article
Objective This study investigated if individual preferences with respect to the trade-off between a good signal-to-noise ratio and a distortion-free speech target were stable across different masking conditions and if simple adjustment methods [...]Article
Background: Field tests and guided walks in real environments show that the benefit from hearing aid (HA) signal processing in real-life situations is typically lower than the predicted benefit found in laboratory studies. This suggests that [...]Article
Maarten van Beurden ; Monique Boymans ; Mirjam van Geleuken ; Dirk Oetting ; Birger Kollmeier ; Wouter A. Dreschler |Objective Current hearing aid prescription rules assume that spectral loudness summation decreases with hearing impairment and that binaural loudness summation is independent of hearing loss and signal bandwidth. Previous studies have shown tha[...]
