Abstract [en]

Hearing loss manifests as a reduced ability to understand speech, particularly in multitalker situations. In these situations, younger normal-hearing listeners' brains are known to track attended speech through phase-locking of neural activity to the slow-varying envelope of the speech. This study investigates how hearing loss, compensated by hearing aids, affects the neural tracking of the speech-onset envelope in elderly participants with varying degree of hearing loss (n = 27, 62–86 yr; hearing thresholds 11–73 dB hearing level). In an active listening task, a to-be-attended audiobook (signal) was presented either in quiet or against a competing to-be-ignored audiobook (noise) presented at three individualized signal-to-noise ratios (SNRs). The neural tracking of the to-be-attended and to-be-ignored speech was quantified through the cross-correlation of the electroencephalogram (EEG) and the temporal envelope of speech. We primarily investigated the effects of hearing loss and SNR on the neural envelope tracking. First, we found that elderly hearing-impaired listeners' neural responses reliably track the envelope of to-be-attended speech more than to-be-ignored speech. Second, hearing loss relates to the neural tracking of to-be-ignored speech, resulting in a weaker differential neural tracking of to-be-attended vs. to-be-ignored speech in listeners with worse hearing. Third, neural tracking of to-be-attended speech increased with decreasing background noise. Critically, the beneficial effect of reduced noise on neural speech tracking decreased with stronger hearing loss. In sum, our results show that a common sensorineural processing deficit, i.e., hearing loss, interacts with central attention mechanisms and reduces the differential tracking of attended and ignored speech.

Abstract [en]

We still have very little knowledge about how ourbrains decouple different sound sources, which is known assolving the cocktail party problem. Several approaches; includingERP, time-frequency analysis and, more recently, regression andstimulus reconstruction approaches; have been suggested forsolving this problem. In this work, we study the problem ofcorrelating of EEG signals to different sets of sound sources withthe goal of identifying the single source to which the listener isattending. Here, we propose a method for finding the number ofparameters needed in a regression model to avoid overlearning,which is necessary for determining the attended sound sourcewith high confidence in order to solve the cocktail party problem.

Abstract [en]

Objective: The aim of the current study was to assess aided speech-in-noise outcomes and relate those measures to auditory sensitivity and processing, different types of cognitive processing abilities, and signal processing in hearing aids.

Material and method: Participants were 200 hearing-aid wearers, with a mean age of 60.8 years, 43% females, with average hearing thresholds in the better ear of 37.4 dB HL. Tests of auditory functions were hearing thresholds, DPOAEs, tests of fine structure processing, IHC dead regions, spectro-temporal modulation, and speech recognition in quiet (PB words). Tests of cognitive processing function were tests of phonological skills, working memory, executive functions and inference making abilities, and general cognitive tests (e.g., tests of cognitive decline and IQ). The outcome test variables were the Hagerman sentences with 50 and 80% speech recognition levels, using two different noises (stationary speech weighted noise and 4-talker babble), and three types of signal processing (linear gain, fast acting compression, and linear gain plus a non-ideal binary mask). Another sentence test included typical and atypical sentences with contextual cues that were tested both audio-visually and in an auditory mode only. Moreover, HINT and SSQ were administrated.

Analysis: Factor analyses were performed separate for the auditory, cognitive, and outcome tests.

Results: The auditory tests resulted in two factors labeled SENSITIVITY and TEMPORAL FINE STRUCTURE, the cognitive tests in one factor (COGNITION), and the outcome tests in the two factors termed NO CONTEXT and CONTEXT that relates to the level of context in the different outcome tests. When age was partialled out, COGNITION was moderately correlated with the TEMPORAL FINE STRUCTURE and NO CONTEXT factors but only weakly correlated with the CONTEXT factor. SENSITIVITY correlated weakly with TEMPORAL FINE STRUCTURE and CONTEXT, and moderately with NO CONTEXT, while TEMPORAL FINE STRUCTURE showed weak correlation with CONTEXT and moderate correlation with NO CONTEXT. CONTEXT and NO CONTEXT had a  moderate correlation. Moreover, the overall results of the Hagerman sentences showed 0.9 dB worse SNR with fast acting compression compared with linear gain and 5.5 dB better SNR with linear  gain and noise reduction compared with only linear gain.

Conclusions: For hearing aid wearers, the ability to recognize speech in noise is associated with both sensory and cognitive processing abilities when the speech materials have low internal context. These associations are less prominent when the speech material has contextual cues.

Abstract [en]

Objective: This study provides descriptive statistics of the Danish reading span (RS) test for hearing-impaired adults. The combined effect of hearing loss, RS score, and age on speech-in-noise performance in different spatial settings was evaluated in a subset of participants. Design: Data from published and unpublished studies were re-analysed. Data regarding speech-in-noise performance with co-located or spatially separated sound sources were available for a subset of participants. Study sample: RS scores from 283 hearing-impaired participants were extracted from past studies, and 239 of these participants had completed a speech-in-noise test. Results: RS scores (mean = 41.91%, standard deviation = 11.29%) were related to age (p <0.01), but not pure-tone average (PTA) (p = 0.29). Speech-in-noise performance for co-located sound sources was related to PTA and RS score (both p < 0.01, adjusted R-squared = 0.226). Performance for spatially separated sounds was related to PTA (p < 0.01, adjusted R-squared = 0.10) but not RS score (p = 0.484). We found no differences between the standardized coefficients of the two regression models. Conclusions: The distribution of RS scores indicated a high test difficulty. We found that age should be controlled when RS scores are compared across populations. The experimental setup of the speech-in-noise test may influence the relationship between performance and RS score.

Abstract [en]

The Fifth Eriksholm Workshop on "Hearing Impairment and Cognitive Energy" was convened to develop a consensus among interdisciplinary experts about what is known on the topic, gaps in knowledge, the use of terminology, priorities for future research, and implications for practice. The general term cognitive energy was chosen to facilitate the broadest possible discussion of the topic. It goes back to Titchener (1908) who described the effects of attention on perception; he used the term psychic energy for the notion that limited mental resources can be flexibly allocated among perceptual and mental activities. The workshop focused on three main areas: (1) theories, models, concepts, definitions, and frameworks; (2) methods and measures; and (3) knowledge translation. We defined effort as the deliberate allocation of mental resources to overcome obstacles in goal pursuit when carrying out a task, with listening effort applying more specifically when tasks involve listening. We adapted Kahnemans seminal (1973) Capacity Model of Attention to listening and proposed a heuristically useful Framework for Understanding Effortful Listening (FUEL). Our FUEL incorporates the well-known relationship between cognitive demand and the supply of cognitive capacity that is the foundation of cognitive theories of attention. Our FUEL also incorporates a motivation dimension based on complementary theories of motivational intensity, adaptive gain control, and optimal performance, fatigue, and pleasure. Using a three-dimensional illustration, we highlight how listening effort depends not only on hearing difficulties and task demands but also on the listeners motivation to expend mental effort in the challenging situations of everyday life.

Abstract [en]

OBJECTIVE: Acceptance and readiness to seek professional help have shown to be important factors for favourable audiological rehabilitation outcomes. Theories from health psychology such as the transtheoretical (stages-of-change) model could help understand behavioural change in people with hearing impairment. In recent studies, the University of Rhode Island change assessment (URICA) has been found to have good predictive validity.

DESIGN: In a previous study, 224 Swedish adults who had failed an online hearing screening completed URICA and two other measures of stages of change. This follow-up aimed to: (1) determine prevalence of help-seeking at a hearing clinic and hearing aid uptake, and (2) explore the predictive validity of the stages of change measures by a follow-up on the 224 participants who had failed a hearing screening 18 months previously.

STUDY SAMPLE: A total of 122 people (54%) completed the follow-up online questionnaire, including the three measures and questions regarding experience with hearing help-seeking and hearing aid uptake.

RESULTS: Since failing the online hearing screening, 61% of participants had sought help. A good predictive validity for a one-item measure of stages of change was reported.

CONCLUSIONS: The Staging algorithm was the stages of change measure with the best ability to predict help-seeking 18 months later.

Abstract [en]

Context Although the pupil light reflex has been widely used as a clinical diagnostic tool for autonomic nervous system dysfunction, there is no systematic review available to summarize the evidence that the pupil light reflex is a sensitive method to detect parasympathetic dysfunction. Meanwhile, the relationship between parasympathetic functioning and hearing impairment is relatively unknown. Objectives To 1) review the evidence for the pupil light reflex being a sensitive method to evaluate parasympathetic dysfunction, 2) review the evidence relating hearing impairment and parasympathetic activity and 3) seek evidence of possible connections between hearing impairment and the pupil light reflex. Methods Literature searches were performed in five electronic databases. All selected articles were categorized into three sections: pupil light reflex and parasympathetic dysfunction, hearing impairment and parasympathetic activity, pupil light reflex and hearing impairment. Results Thirty-eight articles were included in this review. Among them, 36 articles addressed the pupil light reflex and parasympathetic dysfunction. We summarized the information in these data according to different types of parasympathetic-related diseases. Most of the studies showed a difference on at least one pupil light reflex parameter between patients and healthy controls. Two articles discussed the relationship between hearing impairment and parasympathetic activity. Both studies reported a reduced parasympathetic activity in the hearing impaired groups. The searches identified no results for pupil light reflex and hearing impairment. Discussion and Conclusions As the first systematic review of the evidence, our findings suggest that the pupil light reflex is a sensitive tool to assess the presence of parasympathetic dysfunction. Maximum constriction velocity and relative constriction amplitude appear to be the most sensitive parameters. There are only two studies investigating the relationship between parasympathetic activity and hearing impairment, hence further research is needed. The pupil light reflex could be a candidate measurement tool to achieve this goal.

Abstract [en]

Objective: The aim of the study was to investigate the utility of an internet-based version of the trail making test (TMT) to predict performance on a speech-in-noise perception task.

Design: Data were taken from a sample of 1509 listeners aged between 18 and 91 years old. Participants completed computerized versions of the TMT and an adaptive speech-in-noise recognition test. All testing was conducted via the internet.

Results: The results indicate that better performance on both the simple and complex subtests of the TMT are associated with better speech-in-noise recognition scores. Thirty-eight percent of the participants had scores on the speech-in-noise test that indicated the presence of a hearing loss.

Conclusions: The findings suggest that the TMT may be a useful tool in the assessment, and possibly the treatment, of speech-recognition difficulties. The results indicate that the relation between speech-in-noise recognition and TMT performance relates both to the capacity of the TMT to index processing speed and to the more complex cognitive abilities also implicated in TMT performance.

Abstract [en]

Purpose Seeing the talker's face improves speech understanding in noise, possibly releasing resources for cognitive processing. We investigated whether it improves free recall of spoken two-digit numbers.

Method Twenty younger adults with normal hearing and 24 older adults with hearing loss listened to and subsequently recalled lists of 13 two-digit numbers, with alternating male and female talkers. Lists were presented in quiet as well as in stationary and speech-like noise at a signal-to-noise ratio giving approximately 90% intelligibility. Amplification compensated for loss of audibility.

Results Seeing the talker's face improved free recall performance for the younger but not the older group. Poorer performance in background noise was contingent on individual differences in working memory capacity. The effect of seeing the talker's face did not differ in quiet and noise.

Conclusions We have argued that the absence of an effect of seeing the talker's face for older adults with hearing loss may be due to modulation of audiovisual integration mechanisms caused by an interaction between task demands and participant characteristics. In particular, we suggest that executive task demands and interindividual executive skills may play a key role in determining the benefit of seeing the talker's face during a speech-based cognitive task
