Personality and age capture dissociations of subjective versus objective noise tolerance

Malte Wöstmann1,2, Julia Erb1,2, Jens Kreitewolf 1,2,3,4, Jonas Obleser1,21Department of Psychology, University of Lübeck, Lübeck, Germany     2Center of Brain, Behaviour, and Metabolism, University of Lübeck, Lübeck, Germany;3Department of Psychology, McGill University, Montreal, Quebec, Canada;4Department of Mathematics and Statistics, McGill University, Montreal, Quebec, Canada Acoustic noise is pervasive in human environments. Some individuals are more tolerant to …

The role of fundamental-frequency dynamic-range contrast in competing-talker scenarios

Paolo A. Mesiano1, Johannes Zaar1,2, Lars Bramsløw2, Helia Relaño-Iborra1,3, Torsten Dau11Hearing Systems Section, Department of Health Technology, Technical University of Denmark, Kongens Lyngby, Denmark2Eriksholm Research Centre, Snekkersten, Denmark3Cognitive Systems Section, Department of Applied Mathematics and Computer Science, Technical University of Denmark, Kongens Lyngby, Denmark The effects of fundamental-frequency (F0) cues on speech intelligibility in competing-talker …

Masking release with non-stationary speech-like stimuli

Hyojin Kim1, Viktorija Ratkute1, Bastian Epp11Hearing Systems Section, Department of Health Technology, Technical University of Denmark, Lyngby, Denmark Comodulated masking noise and binaural cues can facilitate detecting a target sound from noise. These cues induce a decrease in detection thresholds, quantified as comodulation masking release (CMR) and binaural masking level difference (BMLD), respectively. Previous studies …

Spectral changes of Russian vowels pronounced in babble noise

Alexander Lunichkin1, Alisa Gvozdeva1, Larisa Zaitseva1, Elena Ogorodnikova2, Irina Andreeva11Laboratory of comparative sensory physiology, Sechenov Institute of Evolutionary Physiology and Biochemistry of Russian Academy of Sciences, Saint Petersburg, Russia2Pavlov Institute of Physiology of Russian Academy of Sciences, Saint Petersburg, Russia Lombard reflex improves quality of speech communication in noisy environments. The reflex modifies amplitude-frequency parameters …

Individual differences in auditory continuity perception and its relationship with phonemic restoration of speech in normal hearing individuals

Srikar Vijayasarathy1, Animesh Barman21Department of Audiology, JSS Institute of Speech and Hearing, Mysuru, India2Department of Audiology, All India Institute of Speech and Hearing, Mysuru, India The study investigated illusory auditory continuity percept of the vowel /a/, and its relationship with the phonemic restoration of speech in noise in 25 individuals with normal hearing. The perception …

Rollover effects at higher-than-normal levels in speech materials with low but not high context

Michal Feręczkowski1,2, Benedikte Degn Mikkelsen1, Tobias Neher1,21Department of Clinical Research, Faculty of Health Sciences, University of Southern Denmark, Odense, Denmark2Research Unit for ORL – Head & Neck Surgery and Audiology, Odense University Hospital, Odense, Denmark; University of Southern Denmark, Odense, Denmark The dependence of speech intelligibility on the presentation level has traditionally been modelled with …

(How) do transparent hearing aids impair speech intelligibility in normal hearing subjects?

Florian Denk1, Florian Miethling1, Jürgen Tchorz2, Hendrik Husstedt11Deutsches Hörgeräte Institut GmbH, Lübeck, Germany2Technische Hochschule Lübeck, Germany While hearing aids provide large benefits for hearing impaired users, it has been repeatedly shown that wearing hearing aids has also detrimental effects on sound localization, spatial hearing and speech perception. Such ‘side effects’ reduce the benefit of hearing …

Investigating the effects of short hearing-aid processing delays on perceived sound quality

Ellen Lundorff1,2,3, Rasmus Skipper4, Tobias Neher1,2, Georg Stiefenhofer31Institute of Clinical Research, Faculty of Health Sciences, University of Southern Denmark, Odense, Denmark2Research Unit for ORL – Head & Neck Surgery and Audiology, Odense University Hospital, Odense, Denmark; University of Southern Denmark, Odense, Denmark3Scientific Audiology, WS Audiology A/S, Lynge, Denmark4Dept. of Audiology, Odense University Hospital, Odense, Denmark …

Technical evaluation of impulse noise reduction in hearing aids

Hendrik Husstedt1, Wiebke Hilgerdenaar1,2, Marlitt Frenz1, Florian Denk 1, Jürgen Tchorz3, Simone Wollermann11German Institute of Hearing Aids, Lübeck, Germany2Universität zu Lübeck, Lübeck, Germany3Technische Hochschule Lübeck, Lübeck, Germany Hearing aid users often report that short, impulse-like noise signals with high sound pressure levels such as slamming of a door or rattle of dishes are particularly annoying. …

Objective evaluation of dynamic range compression in adverse acoustic conditions using a data-driven distance metric

Niels Overby1, Torsten Dau1, Tobias May11Hearing Systems Section, Department of Health Technology, Technical University of Denmark, Kgs. Lyngby, Denmark Dynamic range compression aims to restore audibility for hearing-impaired listeners and is one of the most essential building blocks in modern hearing aids. However, the choice of suitable compression parameters, such as the time constants associated …
