Hearing Impairment and Cognitive Energy: The Framework for Understanding Effortful Listening (FUEL)

Ear and Hearing (2016)

M. Kathleen Pichora‐Fuller Sophia E. Kramer Mark A. Eckert Brent Edwards Benjamin W. Y. Hornsby

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 Kahneman’s 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 listener’s motivation to expend mental effort in the challenging situations of everyday life.

Diverse field spectroscopy: instrument concepts

Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE (2010)

Graham J. Murray J. R. Allington‐Smith Simon Blake Robert Content Ulrike Lemke

We are currently developing a range of instrument concepts which combine the advantages of integral field and multiobject systems. They are modular, arbitrarily scalable, and will be capable of addressing large fields with extremely high efficiency. We have coined the phrase 'Diverse Field Spectroscopy' to describe this paradigm shift in instrument versatility. For such instruments, downselection to extract sub-sets of data from the focal plane is key. Whereas other existing and proposed instruments (multiplex, multiple-field) use individual deployable fibres, IFUs or field pickoff mechanisms to select regions from the field, the focus in Durham has been on implementing the downselection by means of optical switches. We believe that optical switching will be a foundation-technology for future ELTs. Several of our most promising concepts will be presented in this paper.

P2‐406: Treatment of Hearing Impairment in Older Adults with Cognitive Impairment: Importance of Including Significant Others

Alzheimer s & Dementia (2016)

Kate Dupuis Ulrike Lemke Marilyn Reed M. Kathleen Pichora‐Fuller

The incidence of cognitive impairment increases with age. Given that the average age of first time hearing aid use is 70, it is likely that many hearing aid users will experience concomitant decline in their cognitive function. Indeed, mounting evidence suggests that those with hearing impairment are at greater risk for cognitive impairment and dementia than those with good hearing. Individuals experiencing cognitive impairment, and especially those with dementia, may be less likely to wear their device as prescribed unless they have support. In these instances, it may be the patient’s significant other, such as their spouse or adult child, who takes responsibility for the use and maintenance of the device and supporting speech communication. It is common for these informal caregivers to experience burden related to their loved one’s hearing impairment, also called “third-party disability”. Significant others may view hearing aids as adding to the burden of care, rather than reducing it, and as a result may be hesitant to seek out amplification as a management option for their care recipient. The majority of research on third-party disability in hearing impairment has failed to take the cognitive status of the patient into account. It is likely that the burden felt would be even higher in instances of concomitant hearing and cognitive impairment. The current study examines the effects of hearing impairment and audiologic rehabilitation on older individuals with cognitive impairment and their family members. Preliminary findings indicate that provision of hearing aids can serve to reduce a spouse’s subjective burden related to communication difficulties, and improve the patient’s ability to engage in social activities and leisure activities such as watching television. We will discuss the findings in the context of potential changes to best practice techniques that could optimize benefits for patients with hearing impairment and cognitive impairment.

10-Year Follow-Up Results of The Netherlands Longitudinal Study on Hearing: Trends of Longitudinal Change in Speech Recognition in Noise

Ear and Hearing (2019)

Thadé Goderie Mariska Stam Birgit I. Lissenberg‐Witte Paul Merkus Ulrike Lemke

Objectives: Previous findings of longitudinal cohort studies indicate that acceleration in age-related hearing decline may occur. Five-year follow-up data of the Netherlands Longitudinal Study on Hearing (NL-SH) showed that around the age of 50 years, the decline in speech recognition in noise accelerates compared with the change in hearing in younger participants. Other longitudinal studies confirm an accelerated loss in speech recognition in noise but mostly use older age groups as a reference. In the present study, we determined the change in speech recognition in noise over a period of 10 years in participants aged 18 to 70 years at baseline. We additionally investigated the effects of age, sex, educational level, history of tobacco smoking, and alcohol use on the decline of speech recognition in noise. Design: Baseline (T0), 5-year (T1), and 10-year (T2) follow-up data of the NL-SH collected until May 2017 were included. The NL-SH is a web-based prospective cohort study which started in 2006. Central to the NL-SH is the National Hearing test (NHT) which was administered to the participants at all three measurement rounds. The NHT uses three-digit sequences which are presented in a background of stationary noise. The listener is asked to enter the digits using the computer keyboard. The outcome of the NHT is the speech reception threshold in noise (SRT) (i.e., the signal to noise ratio where a listener recognizes 50% of the digit triplets correctly). In addition to the NHT, participants completed online questionnaires on demographic, lifestyle, and health-related characteristics at T0, T1, and T2. A linear mixed model was used for the analysis of longitudinal changes in SRT. Results: Data of 1349 participants were included. At the start of the study, the mean age of the participants was 45 years (SD 13 years) and 61% of the participants were categorized as having good hearing ability in noise. SRTs significantly increased (worsened) over 10 years ( p < 0.001). After adjustment for age, sex, and a history of tobacco smoking, the mean decline over 10 years was 0.89 dB signal to noise ratio. The decline in speech recognition in noise was significantly larger in groups aged 51 to 60 and 61 to 70 years compared with younger age groups (18 to 30, 31 to 40, and 41 to 50 years) ( p < 0.001). Speech recognition in noise in participants with a history of smoking declined significantly faster during the 10-year follow-up interval ( p = 0.003). Sex, educational level, and alcohol use did not appear to influence the decline of speech recognition in noise. Conclusions: This study indicated that speech recognition in noise declines significantly over a 10-year follow-up period in adults aged 18 to 70 years at baseline. It is the first longitudinal study with a 10-year follow-up to reveal that the increased rate of decline in speech recognition ability in noise already starts at the age of 50 years. Having a history of tobacco smoking increases the decline of speech recognition in noise. Hearing health care professionals should be aware of an accelerated decline of speech recognition in noise in adults aged 50 years and over.

Self-reported hearing handicap in adults aged 55 to 81 years is modulated by hearing abilities, frailty, mental health, and willingness to use hearing aids

International Journal of Audiology (2021)

Theresa Nuesse Anne Schlueter Ulrike Lemke Inga Holube

Objective The aim of this study was to predict outcomes of the HHI questionnaire (Hearing Handicap Inventory) using individual variables beyond pure-tone hearing thresholds.Design An extensive health-related test battery was applied including a general anamnesis, questionnaires, audiological measures, examination of visual acuity, balance, and cognition, as well as tactile- and motor skills. Based on the self-assessment of health variables and different sensory and cognitive performance measures, a frailty index was calculated to describe the health status of the participants. A stepwise linear regression analysis was conducted to predict HHI scores.Study sample A mixed sample (N = 212) of 55- to 81-year-old, participants with different hearing and aiding status completed the test battery.Results The regression analysis showed statistically significant contributions of pure-tone hearing thresholds, speech recognition in noise, age, frailty, mental health, and the willingness to use hearing aids on HHIE outcomes.Conclusions Self-reported hearing handicap assessed with the HHI questionnaire reflects various individual variables additionally to pure-tone hearing loss and speech recognition in noise. It is necessary to be aware of the influences of age and health-related variables on HHI scores when using it in research as well as in clinical settings.

The CARMENES search for exoplanets around M dwarfs. HD147379 b : A nearby Neptune in the temperate zone of an early-M dwarf

Astronomy and Astrophysics (2018)

A. Reiners I. Ribas M. Zechmeister J. A. Caballero T. Trifonov

We report on the first star discovered to host a planet detected by radial velocity (RV) observations obtained within the CARMENES survey for exoplanets around M dwarfs. HD 147379 (V = 8.9 mag, M = 0.58 +/- 0.08 M-circle dot), a bright M0.0 V star at a distance of 10.7 pc, is found to undergo periodic RV variations with a semi-amplitude of K = 5.1 +/- 0.4 m s(-1) and a period of P = 86.54 +/- 0.06 d. The RV signal is found in our CARMENES data, which were taken between 2016 and 2017, and is supported by HIRES/Keck observations that were obtained since 2000. The RV variations are interpreted as resulting from a planet of minimum mass m(P) sin i = 25 +/- 2 M-circle plus, 1.5 times the mass of Neptune, with an orbital semi-major axis a = 0.32 au and low eccentricity (e < 0.13). HD 147379 b is orbiting inside the temperate zone around the star, where water could exist in liquid form. The RV time-series and various spectroscopic indicators show additional hints of variations at an approximate period of 21.1 d (and its first harmonic), which we attribute to the rotation period of the star.

The CARMENES search for exoplanets around M dwarfs

Astronomy and Astrophysics (2017)

A. Reiners M. Zechmeister J. A. Caballero I. Ribas J. C. Morales

The CARMENES radial velocity (RV) survey is observing 324 M dwarfs to search for any orbiting planets. In this paper, we present the survey sample by publishing one CARMENES spectrum for each M dwarf. These spectra cover the wavelength range 520--1710nm at a resolution of at least $R > 80,000$, and we measure its RV, H$\alpha$ emission, and projected rotation velocity. We present an atlas of high-resolution M-dwarf spectra and compare the spectra to atmospheric models. To quantify the RV precision that can be achieved in low-mass stars over the CARMENES wavelength range, we analyze our empirical information on the RV precision from more than 6500 observations. We compare our high-resolution M-dwarf spectra to atmospheric models where we determine the spectroscopic RV information content, $Q$, and signal-to-noise ratio. We find that for all M-type dwarfs, the highest RV precision can be reached in the wavelength range 700--900nm. Observations at longer wavelengths are equally precise only at the very latest spectral types (M8 and M9). We demonstrate that in this spectroscopic range, the large amount of absorption features compensates for the intrinsic faintness of an M7 star. To reach an RV precision of 1ms$^{-1}$ in very low mass M dwarfs at longer wavelengths likely requires the use of a 10m class telescope. For spectral types M6 and earlier, the combination of a red visual and a near-infrared spectrograph is ideal to search for low-mass planets and to distinguish between planets and stellar variability. At a 4m class telescope, an instrument like CARMENES has the potential to push the RV precision well below the typical jitter level of 3-4ms$^{-1}$.
