Abstract [en]

Cognitive abilities are important for a number of human attributes, such as making sense of communication, holding information active in memory, and making decisions. When it is the goal to focus on a single target voice, and resist intrusions from irrelevant information, cognitive inhibition can aid us in our endeavour. Cognitive inhibition is thought to support and co-operate with working memory. Abilities such as cognitive inhibition and working memory are also important for speech processing, even more so when listening to speech under adverse conditions. In order to assess different difficulties that can arise in every day listening situations, it´s of importance to have solid methods for measuring cognitive abilities. In the present study we present a task assessing cognitive inhibition, and how it relates to individual working memory capacity (WMC), and speech-recognition-in-noise. Forty-six young normally-hearing individuals were presented with a cognitive test battery, as well as a speech-in-noise test. Our results suggest that individuals with high WMC, also exhibit good cognitive inhibition. The results also indicate that those who perform well in the cognitive inhibition task need less favourable signal-to-noise-ratios in the speech-recognition task. Our findings indicate that capacity to resist semantic interference can be used to predict performance in speech-recognition tasks when listening under adverse conditions.

Abstract [en]

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

Abstract [en]

Purpose: To investigate the effect of female versus male speakers’ voice on the ability to recognize speech innoise in two groups of sensorineural hearing-impaired listeners, one group with impairment at lowfrequencies and the other at high frequencies.Method: Eight participants with high-frequency hearing impairments (Hf-HI) and seven with low-frequencyhearing impairments (Lf-HI) participated. Sixteen normal hearing (NH) participants served as reference.The sentences from the hearing in noise test, read by a female or a male speaker, were presentedmonaurally with a background noise. In an adaptive procedure, the mean speech recognition threshold,for 50% correctly recognized sentences, was calculated for the female and male voice and each test subject.Results: The Hf-HI group had significantly greater difference in signal-to-noise ratio (SNR) results betweenfemale and male voices. Irrespective of hearing impairment, the female voice required 2.1 dB better SNR.In addition, the NH group showed a small but significant difference in favor of the male voice.Conclusions: Results indicate that speaker gender matters for hearing impaired and NH individuals’ ability torecognize speech in noise.

Abstract [en]

Cognitive abilities, such as working memory capacity (WMC), lexical decision making, and cognitive inhibition, can help predict performance on speech-recognition-in-noise tasks. Working memory is assumed to play a major part in every day listening situations, storing and actively working with relevant information, while inhibitory control helps to suppress and separate irrelevant information from interfering with the information processing. With increasing age, comes decreasing cognitive abilities, such as declines in WMC, speed of information processing, and inhibitory control, leading to problems when selectively attending to speech while inhibiting interfering distractors. The aim of the present study was to examine age-related declines in WMC, inhibitory control, and lexical decision making, and their respective roles when listening to speech under adverse listening conditions. Twenty-four young normally-hearing (NH), and 24 elderly ( for their age) NH individuals participated in the study. They completing a cognitive test battery assessing WMC, cognitive inhibition, and lexical decision making, as well as a closed-set (Hagerman sentences) and an open-set (HINT) speech-recognition-in-noise task masked with different maskers. We will present results comparing cognitive abilities in younger normally-hearing individuals with elderly normally-hearing individuals, and how age and cognitive abilities relates to performance on speech-recognition-in-noise tasks.

Abstract [en]

In the present study we aimed to investigate individual differences in cognitive inhibition, WMC, and how they relate to performance on a speech-recognition-in-noise task. Sixteen young normally-hearing individuals were presented with a cognitive test battery, as well as a sentence corpus masked by 5 different maskers, targeting 80% speech-recognition. One masker was a slightly modulated (10%) speech-shaped noise (SSN), 2 maskers were constructed by modulating the SSN with the envelopes from a single female talker, and the international speech test signal (ISTS). We also masked the target sentences with the ISTS, and a single female talker reading a passage in a Swedish newspaper. Our results showed that cognitive inhibition is significantly related to performance when maskers with meaningful, semantic information is used. The results further indicate that young normally-hearing individuals can take advantage of temporal and spectral dips to fill in missing information. Our findings suggest that choice of speech material is of importance for the outcome in speech-recognition-in-noise tasks. We further propose that tasks of cognitive inhibition can be used to predict performance in a speech-recognition task.

Abstract [en]

Cognitive functions and speech-recognition-in-noise were evaluated with a cognitive test battery, assessing response inhibition using the Hayling task, working memory capacity (WMC) and verbal information processing, and an auditory test of speech recognition. The cognitive tests were performed in silence whereas the speech recognition task was presented in noise. Thirty young normally-hearing individuals participated in the study. The aim of the study was to investigate one executive function, response inhibition, and whether it is related to individual working memory capacity (WMC), and how speech-recognition-in-noise relates to WMC and inhibitory control. The results showed a significant difference between initiation and response inhibition, suggesting that the Hayling task taps cognitive activity responsible for executive control. Our findings also suggest that high verbal ability was associated with better performance in the Hayling task. We also present findings suggesting that individuals who perform well on tasks involving response inhibition, and WMC, also perform well on a speech-in-noise task. Our findings indicate that capacity to resist semantic interference can be used to predict performance on speech-in-noise tasks.

Abstract [en]

The present study aimed to investigate the changing relationship between aided speech recognition and cognitive function during the first six months of hearing aid use. Twentyseven first-time hearing aid users with symmetrical mild to moderate sensorineural hearing loss were recruited. Aided speech recognition thresholds in noise (SRTs) were obtained in the hearing aid fitting session as well as at three and six months post-fitting. Cognitive abilities were assessed using a reading span test, which is a measure of working memory capacity, and a cognitive test battery. Results showed a significant correlation between reading span and SRT during the hearing aid fitting session. This relation was significantly weakened over the first six months of hearing aid use. Multiple regression analysis showed that reading span was the main predictor of SRT when hearing aids were first fitted, but that pure-tone average hearing threshold (PTA) was the main predictor six months later. This indicates that working memory capacity plays a more important role in speech recognition in noise before than after six months of use. We argue that new hearing aid users engage working memory capacity to recognize unfamiliar processed speech signals but that as familiarization proceeds, engagement of working memory capacity is reduced.

Abstract [en]

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 and temporal resolution, spatial hearing, self-reported disability and handicap, and cognition. Clinical applicability and comparability across different centres are investigated. Design: Headphone tests were conducted in five centres divided over four countries. Effects of test-retest, ear, and centre were investigated. Results for normally-hearing (NH) and hearing-impaired (HI) listeners are presented. Study sample: Thirty NH listeners aged 19-39 years, and 72 HI listeners aged 22-91 years with a broad range of hearing losses were included. Results: Test-retest reliability was generally good and there were very few right/left ear effects. Results of all tests were comparable across centres for NH listeners after baseline correction to account for necessary differences between test materials. For HI listeners, results were comparable across centres for the language-independent tests. Conclusions: The auditory profile forms a clinical test battery that is applicable in four different languages. Even after baseline correction, differences between test materials have to be taken into account when interpreting results of language-dependent tests in HI listeners.

Abstract [en]

 

Little is known about the relation between the ability to inhibit irrelevant information and perceiving speech-in-noise and the effects of hearing loss and ageing on this relationship. In settings where a listening task is difficult, individuals use both their hearing and cognitive abilities to process the auditory information. To perceive speech in noise, one must focus on the relevant information and at the same time inhibit the processing of irrelevant information. Results from recent studies indicate that older adults have difficulties singling out speech in noise, and selectively attend to target speech while inhibiting irrelevant information.

 

The purpose of the project is to increase theoretical knowledge concerning the relation between age, perceiving speech-in-noise and inhibition. The pilot study involved the administration of a test battery consisting of audiological, cognitive and speech perception tests. The results of a series of ANOVAs and correlational analyses will be presented to show differences in performance and the relation between performance on the cognitive, audiological and speech-perception tasks. Upon completion, the results of this study will be used to compare younger individuals´ performance with older adults with and without hearing loss to determine the effect of age and hearing ability on the relation between capacity to inhibit irrelevant information and speech-in-noise recognition.
