OBJECTIVE The purpose of this study was to assess the influence of dynamic compression on directional hearing in the frontal horizontal plane. DESIGN Compression schemes with various compression ratios and attack times were created by using a digital signal processor. The influence of compression on isolated interaural level differences (ILDs) and(More)
Hearing-aid use in the elderly population is problematic since not all people who would benefit from hearing aids actually obtain one. In this study, the relationship between pre-fitting expectations and willingness to use hearing aids is addressed. One hundred adult hearing aid candidates (mean age 68.6 years) were randomly recruited from eight different(More)
Speech recognition in a multi-talker situation poses high demands on attentional and other central resources. This study examines the relationship between age, cognition and speech recognition in tasks that require selective or divided attention in a multi-talker setting. Two groups of normal-hearing adults (one younger and one older group) were asked to(More)
Auf der Basis eines neurophysiologischen Modells wurde in den letzten Jahren die Retrainingtherapie für Tinnituspatienten entwickelt [9]. Erste Ergebnisse dieser Therapiemaßnahme zeigen bei 40–50% der Patienten mit subakutem oder chronischem Tinnitus eine deutliche Verbesserung sowie bei 20–30% eine komplette Reduktion des Tinnitus [6]. In einer(More)
OBJECTIVE To determine the importance of fundamental hearing aid attributes and to elicit measures of satisfaction and dissatisfaction. STUDY DESIGN A prospective study based on a survey using a decompositional approach of preference measurement (conjoint analysis). SETTING Ear, nose, and throat university hospitals in Cologne and Giessen; various(More)
The purpose of this study was to examine the effects of altering the fundamental frequency (F0) on perception of prosody and speaker gender in both normal-hearing listeners and cochlear implant (CI) recipients. Tests with natural speech and defined modifications of the F0 were performed, and the resulting changes in perception were measured. Compared to the(More)
Hintergrund und Fragestellung. Zur Untersuchung binauraler Hörleistungen, die u. a. das Richtungshören beinhalten, gibt es bislang wenig validierte, klinisch einsetzbare Verfahren.Eine anwendbare elektrophysiologische Methode ist die Erfassung der sog. binauralen Differenzpotenziale (BDP) auf Hirnstammebene. Patienten/Methodik. Das BDP ist definiert als(More)
Frühkindliche hochgradige Hörstörungen wie auch prälinguale Taubheit sollten frühzeitig therapiert werden, um sprachliche, kognitive und soziale Defizite zu vermeiden. Die Versorgung prälingual ertaubter Kinder mit einem Kochleaimplantat (CI) wirft u.a. die Frage nach dem optimalen Implantationszeitpunkt auf, um die sensible Phase des reifenden Hörsystems(More)
OBJECTIVE To examine the prevalence of auditory neuropathy/synaptopathy (AN/AS) in a cohort of children with profound hearing loss. METHODS From 1997 until 2004, 5190 children, aged 1-15 years, whose hearing ability was uncertain or who had risk factors for hearing impairment were investigated with subjective and objective hearing tests. Three thousand(More)
Die vorliegenden Empfehlungen wurden von der Arbeitsgruppe Elektrische Reaktions-Audiometrie (AGERA) der Arbeitsgemeinschaft Deutschsprachiger Audiologen und Neurootologen (ADANO) erstellt. Patientenzielgruppe sind Säuglinge nach nicht bestandenem Neugeborenen-Hörscreening (NHS). Es wird dargestellt, wie die Konfirmationsdiagnostik (Follow-up) mit(More)
