UNLABELLED In patients with moderate to severe high-frequency hearing loss, cochlear damage may include "dead regions" where there are no functional inner hair cells and/or associated neurons. AIM This study examines speech recognition in sensorineural impaired hearing patients with and without cochlear dead regions at high frequencies. METHODS a clinical and experimental study was made of ...

OBJECTIVE To introduce and verify an algorithm designed to administer adaptive speech-in- noise testing to a specified reliability at selectable points on the psychometric function. DESIGN Speech-in-noise performances were measured using BKB sentences presented in diffuse babble-noise, using morphemic scoring. Target of the algorithm was a test-retest standard deviation of 1.13 dB within the ...

PURPOSE Researchers have used the distortion-sensitivity approach in the psychoacoustical domain to investigate the role of auditory processing abilities in speech perception in noise (van Schijndel, Houtgast, & Festen, 2001; Goverts & Houtgast, 2010). In this study, the authors examined the potential applicability of the distortion-sensitivity approach for investigating the role of linguistic ...

OBJECTIVE People with cochlear implants have severe problems with speech understanding in noisy surroundings. This study evaluates and quantifies the effect of two assistive directional microphone systems compared to the standard headpiece microphone on speech perception in quiet surroundings and in background noise, in a laboratory setting developed to reflect a situation whereby the listener ...

In the presence of competing speech or noise, reverberation degrades speech intelligibility not only by its direct effect on the target but also by affecting the interferer. Two experiments were designed to validate a method for predicting the loss of intelligibility associated with this latter effect. Speech reception thresholds were measured under headphones, using spatially separated target ...

This study investigated the effects of simulated cochlear-implant processing on speech reception in a variety of complex masking situations. Speech recognition was measured as a function of target-to-masker ratio, processing condition (4, 8, 24 channels, and unprocessed) and masker type (speech-shaped noise, amplitude-modulated speech-shaped noise, single male talker, and single female talker)....

The aim of this study was the evaluation of hearing threshold in patients with beta thalasemia major. For this purpose, 178 patients who were under regular chelation therapy with desferrioxamine (DFO) were selected and underwent ear, nose, throat examinations and audiological evaluations. Patients were between 4 to 25 years old and 54.9% were male and 45.1% were female. Three patients were excl...

Purpose The visual Text Reception Threshold (TRT) test (Zekveld et al., 2007) has been designed to assess modality-general factors relevant for speech perception in noise. In the last decade, the test has been adopted in audiology labs worldwide. The 1st aim of this study was to examine which factors best predict interindividual differences in the TRT. Second, we aimed to assess the relationshi...
