Objectives: It has been shown that noise reduction algorithms can reduce the negative effects of on memory processing in persons with normal hearing. The objective present study was to investigate whether a similar effect be obtained for hearing impairment and such an is dependent individual differences working capacity. Design: A sentence-final word identification recall (SWIR) test conducted two backgrounds without as well quiet. Working capacity measured using reading span (RS) test....
Objective: The aims of the current n200 study were to assess structural relations between three classes test variables (i.e. HEARING, COGNITION and aided speech-in-noise OUTCOMES) describe theoretical implications these for Ease Language Understanding (ELU) model. Study sample: Participants 200 hard-of-hearing hearing-aid users, with a mean age 60.8 years. Forty-three percent females hearing threshold in better ear was 37.4 dB HL. Design: LEVEL1 factor analyses extracted one per and/or...
A hearing aid noise reduction (NR) algorithm reduces the adverse effect of competing speech on memory for target individuals with impairment high working capacity. In present study, we investigated whether positive NR could be extended to low capacity, as well how influences recall performance native when masker language is non-native.A sentence-final word identification and (SWIR) test was administered 26 experienced users. this test, spoken (Swedish) sentence lists were presented in or...
In adaptive Speech Reception Threshold (SRT) tests used in the audiological clinic, speech is presented at signal to noise ratios (SNRs) that are lower than those generally encountered real-life communication situations. At higher, ecologically valid SNRs, however, SRTs insensitive changes hearing aid processing may be of benefit listeners who hard hearing. Previous studies conducted Swedish using Sentence-final Word Identification and Recall test (SWIR) have indicated such ability recall...
The present study aimed to investigate the changing relationship between aided speech recognition and cognitive function during first 6 months of hearing aid use. Twenty-seven first-time users with symmetrical mild moderate sensorineural loss were recruited. Aided thresholds in noise obtained fitting session as well at 3 postfitting. Cognitive abilities assessed using a reading span test, which is measure working memory capacity, test battery. Results showed significant correlation reception...
Objective: The aim of this study was to examine how background noise and hearing aid experience affect the robust relationship between working memory speech recognition.Design: Matrix sentences were used measure recognition in noise. Three measures administered. Study sample: 148 participants with at least 2 years experience.Results: A stronger overall correlation performance found a four-talker babble than stationary background. This significantly weaker most those when stationary. In...
To increase the ecological validity of outcomes from laboratory evaluations hearing and devices, it is desirable to introduce more realistic outcome measures in laboratory. This article presents discusses three that have been designed go beyond traditional speech-in-noise better reflect everyday challenges. The reviewed are: Sentence-final Word Identification Recall (SWIR) test working memory performance while listening speech noise at ceiling performance; a neural tracking method produces...
Objectives Previous research using non-invasive (magnetoencephalography, MEG) and invasive (electrocorticography, ECoG) neural recordings has demonstrated the progressive hierarchical representation processing of complex multi-talker auditory scenes in cortex. Early responses (<85 ms) primary-like areas appear to represent individual talkers with almost equal fidelity are independent attention normal-hearing (NH) listeners. However, late (>85 higher-order non-primary...
This present study examined the relationship between cognitive measures and self-report hearing aid outcome. A sentence-final word identification recall (SWIR) test was used to investigate how use may relate experienced explicit processing. visually based battery also administered. To measure outcome, International Outcome Inventory - Hearing Aids (IOI-HA) Speech, Spatial Qualities of Scale (SSQ) were employed. Twenty-six users (mean age 59 years) with symmetrical moderate-to-moderately...
Selectively attending to a target talker while ignoring multiple interferers (competing talkers and background noise) is more difficult for hearing-impaired (HI) individuals compared normal-hearing (NH) listeners. Such tasks also become as noise levels increase. To overcome these difficulties, hearing aids (HAs) offer reduction (NR) schemes. The objective of this study was investigate the effect NR processing (inactive, where feature switched off, vs. active, on) on neural representation...
We sought to examine the contribution of visual cues in audiovisual identification consonants and vowels-in terms isolation points (the shortest time required for correct a speech stimulus), accuracy, cognitive demands-in listeners with hearing impairment using aids.The study comprised 199 participants (mean age = 61.1 years) bilateral, symmetrical, mild-to-severe sensorineural loss. Gated Swedish vowels were presented aurally audiovisually participants. Linear amplification was adjusted...
Objectives: Actively following a conversation can be demanding and limited cognitive resources must allocated to the processing of speech, retaining encoding perceived content, preparing an answer. The aim present study was disentangle allocation effort into required for listening ( ) retention memory by means pupil dilation. Design: Twenty-five normal-hearing German speaking participants underwent sentence final word identification recall test, while pupillometry conducted. participants’...
Objectives: Communication requires cognitive processes which are not captured by traditional speech understanding tests. Under challenging listening situations, more working memory resources needed to process speech, leaving fewer available for storage. The aim of the current study was investigate effect task difficulty predictability, that is, knowing versus in advance, and noise reduction on resource allocation processing storage heard background noise. For this purpose, an “offline”...
The aim of the current study was to investigate whether task-evoked pupillary responses measured during encoding, individual working memory capacity and noise reduction in hearing aids were associated with likelihood subsequently recalling an item auditory free recall test combined pupillometry. Participants mild moderately severe symmetrical sensorineural loss (n = 21) included. Sentence-final Word Identification Recall (SWIR) administered a background composed sixteen talkers activated...
This study examined (1) the effects of noise on speech understanding and (2) whether performance in real-life noises could be predicted based steady-state speech-spectrum-shaped noise. The conditions included a six types Thirty normal-hearing adults were tested using sentence materials from Cantonese Hearing In Noise Test (CHINT). To achieve first aim, performance–intensity function slopes these estimated compared. Variations attributed to differences amount amplitude fluctuations presence...
Despite the evidence of a positive relationship between task demands and listening effort, Framework for Understanding Effortful Listening (FUEL) highlights important role arousal on an individual's choice to engage in challenging tasks. Previous studies have interpreted physiological responses conjunction with behavioral as markers engagement. The aim current study was investigate effect potential changes arousal, indexed by pupil baseline, engagement over course auditory recall test....
We have previously shown that the gain provided by prior audiovisual (AV) speech exposure for subsequent auditory (A) sentence identification in noise is relatively larger than A exposure. called this effect "perceptual doping." Specifically, AV processing dopes (recalibrates) phonological and lexical maps mental lexicon, which facilitates access modality, separately from other learning priming effects. In article, we use data n200 study aim to replicate extend perceptual doping using two...
In the present study, we investigated whether varying task difficulty of Sentence-Final Word Identification and Recall (SWIR) Test has an effect on benefit noise reduction, as well predictability affects recall. The relationship between working memory recall was examined.Task manipulated by list length with reduction off in competing speech speech-shaped noise. Half participants were informed about advance. Working capacity measured using Reading Span.Thirty-two experienced hearing aid users...
