Exploring the relationship between technology use,hearing help-seeking,and hearing aid outcomes in older adults

Abstract

Objective: The objective of this study was to explore technology use and its relationship to help-seeking for hearing impairment (HI) and success with hearing aids among older adults. Previous research had suggested a link between higher levels of technology use and hearing aid success. Design: General technology use was evaluated using a purposefully developed 25-item questionnaire. Twelve items related to everyday technology use (e.g. DVD player) and 13 related to advanced technology use (e.g. Bluetooth). Study sample: Four groups of older adults with HI participated in the study: (1) non-consulters (n = 49), (2) consulters (n = 62), (3) unsuccessful hearing aid owners (n = 61), and (4) successful hearing aid owners (n = 79). Results: Preliminary analyses revealed a main effect in the use of everyday and advanced technology across the four participant groups. However, it was found that age and living arrangements accounted for most of the variance in reported everyday technology use (p = .030; p = .029, respectively) and age and gender accounted for the variance in reported advanced technology use (p <.001; p = .040, respectively). For everyday technology, an increase in age and living alone were associated with decreased technology use and for advanced technology use, age and female gender were associated with decreased technology use. Conclusions: Although we hypothesized that technology use would be less amongst non-consulters and unsuccessful hearing aid owners, our findings did not support this prediction. Technology use did not vary by group membership once the covariates of age, gender, and living arrangements were accounted for.     

Speech recognition according to the length of hearing aid use

The use of hearing aids can provide plasticity to the hearing system as well as improve speech recognition as time goes by.AimTo compare the influence of the length of hearing aid use on the benefit obtained with the hearing aids in adults and the elderly, new hearing aids users.Materials and methodsProspective study with 40 individuals with mild to moderate-severe sensorineural hearing loss, gathered in 2 groups: Adults Group – 13 people aged between 28 and 59 years old; and Elderly Group – 27 people aged between 61 and 78 years old. These people were assessed 14 and 90 days after hearing aid fitting. Sentence recognition threshold in silence and under noise as well as the percentage indexes of sentences recognition in silence and under noise were obtained.ResultsThe comparison between values obtained after 14 and 90 days of hearing aid use did not show statistically significant differences. When comparing values between the groups, no statistically significant difference was observed either.ConclusionWe did not find influences of the length of hearing aid use and the benefit obtained from using them; the results achieved by adults and the elderly were similar.     

Impact of Aging and Cognition on Hearing Assistive Technology Use

Many factors go into appropriate recommendation and use of hearing assistive technology (HAT). The aging auditory system presents with its own complications and intricacies; there are many types of age-related hearing loss, and it is possible that the underlying cause of hearing loss can significantly impact the recommendations and performance with HATs. The audiologist should take into consideration peripheral and central auditory function when selecting HATs for the aging adult population as well as when selecting appropriate types of technology including personal sound amplification products, hearing aids, cochlear implants, and other assistive technology. The cognitive ability of the patient plays a central role in the recommendations of HAT. It is possible that the use of HATs could mitigate some of the effects of cognitive decline and thus should be considered as early as possible. Assessment of ability and appropriate recommendations are crucial to consistent use of HAT devices.     

Tone identification in Mandarin-speaking children with profound hearing impairment

ObjectivesLittle is known about the tone identification ability of Mandarin-speaking children with profound hearing impairment (HI) and fitted with hearing aids (HAs). The present study aimed to evaluate the Mandarin tone identification ability in children with profound HI and fitted with HAs, and explore the effects of hearing thresholds, the age of first HA fitting and the duration of HA use on Mandarin tone identification ability.MethodsSubjects were Mandarin-speaking children aged 5;4–12;6 years with profound HI (n = 41). The Mandarin Tone Identification Test was administered in five test conditions: in −10, −5, 0 and 5 dB signal-to-noise ratios (S/Ns) and quiet. Hearing aids were in the usual user's settings, optimized for the best speech reception, and the volume was set to comfortable listening level.ResultsTwo-way repeated measures ANOVA showed significant effects of test conditions and tone contrasts in Mandarin tone identification. Post-hoc pairwise comparisons showed significant difference in performance among the five test conditions. Results also indicated that, among the six tone contrasts, the Tone 1/Tone 2 and Tone 2/Tone 3 contrasts were the most difficult tone contrasts in quiet. No significant difference in performance was found among the six tone contrasts in noise. Pearson product-moment correlation showed that the age of first HA fitting, the duration of HA use, aided and unaided average thresholds as well as the aided hearing thresholds in the low frequency region were not significantly correlated with tone identification ability in the five test conditions.ConclusionsConsistent with previous findings, the Tone 1/Tone 2 and Tone 2/Tone 3 contrasts were the most difficult to identify in quiet; but the presence of noise resulted in these tone contrasts being equally difficult. Findings also suggest that the tone identification ability of children with profound HI needs to be improved. Although the age of first HA fitting and the duration of HA use were not significantly correlated with tone identification performance in children with profound HI, this finding does not preclude the importance of early HA fitting.

Prediction of the use of conventional hearing aids in Korean adults with unilateral hearing impairment

Objective: To determine the use of a hearing aid at six months post-fitting and to evaluate the predictors of its ongoing use in Korean adults with unilateral hearing impairment (HI). Design: Retrospective study at a secondary referral hospital over a 15-year period. Study sample: This study analysed 119 adults with unilateral HI who had been recommended for hearing amplification (55 men and 64 women, mean age, 58.0 ± 11.7 years). Six months after the fitting, all of the participants were surveyed regarding subsequent decisions and actions about obtaining hearing aids. Results: General uptake rate for a hearing aid was 68.1% (58.0% of participants surveyed were successful users, and 10.1% were intermittent users). The most significant parameter associated with hearing-aid use was social and/or work activities (R² = 0.457), and the significant predictors for successful hearing-aid use were social and/or work activities and method of signal processing (discriminatory power = 56.3%). Conclusions: Six months post-fitting, 68.1% of Korean adults with unilateral HI who had agreed to try a hearing aid continued to use it regularly. The predictors for hearing-aid use six months post-fitting included social and/or work activities and digital signal processing.     

Factors influencing degree of hearing loss at presentation,hearing aid choice,and usage in first time hearing aid users in Singapore

Abstract

Objective: To examine the factors associated with late presentation at first hearing aid (HA) fitting, HA choice and usage among users in Singapore.

Design: Retrospective cross-sectional study.

Study sample: 1068 subjects issued with HAs at a tertiary hospital from 2001 to 2013.

Results: Half of the subjects presented with more severe (>55?dB) hearing loss (HL) in their better ear. In multivariable analysis, older age, Malay ethnicity, conductive and mixed HL, and combination type of HL were associated with more severe HL at first presentation. Over 70% of subjects were older than 65 years. Worse pure tone audiometry (PTA) thresholds of the better ear, gradual onset and sensorineural HL were associated with older age presentation. For unilaterally fitted subjects, PTA thresholds were the only determinant of having the better ear aided. Better PTA thresholds, younger age and sensorineural HL were associated with choosing in ear compared to behind the ear HAs. Younger age and worse PTA of the better ear were associated with ≥4?h of daily HA usage.

Conclusions: Age, ethnicity and type of HL were important determinants for more severe HL at first HA fitting. Older patients and those with better hearing were less likely to use their HAs regularly.     

The interaction of hearing loss and level-dependent hearing protection on speech recognition in noise

Abstract

Objectives: To determine the effects of different control settings of level-dependent hearing protectors on speech recognition performance in interaction with hearing loss. Design: Controlled laboratory experiment with two level-dependent devices (Peltor^® PowerCom Plus? and Nacre QuietPro^®) in two military noises. Study sample: Word recognition scores were collected in protected and unprotected conditions for 45 participants grouped into four hearing profile categories ranging from within normal limits to moderate-to-severe hearing loss. Results: When the level-dependent mode was switched off to simulate conventional hearing protection, there were large differences across hearing profile categories regarding the effects of wearing the devices on speech recognition in noise; participants with normal hearing showed little effect while participants in the most hearing-impaired category showed large decrements in scores compared to unprotected listening. Activating the level-dependent mode of the devices produced large speech recognition benefits over the passive mode at both low and high gain pass-through settings. The category of participants with the most impaired hearing benefitted the most from the level-dependent mode. Conclusions: The findings indicate that level-dependent hearing protection circuitry can provide substantial benefits in speech recognition performance in noise, compared to conventional passive protection, for individuals covering a wide range of hearing losses.     

Exploring hearing aid use in older women through narratives

Abstract

This study explored experiences surrounding hearing aid use and non-use in older women with hearing loss. A narrative approach was used to gain an in-depth understanding of the meaning and contextual issues that impact upon the adaptation process of older adults and their transitions in using hearing devices. Four women over the age of sixty who were identified as being consistent hearing aid users took part in three face-to-face interviews. biographic-narrative-interview guiding framework was used to gather data in this study. Data were analyzed both holistically and thematically from a phenomenological perspective to identify the meaning and essence of the participants’ experiences. The results revealed an overarching theme of meaningful participation in life situations and events that were linked to purposeful use and non-use of hearing aids. Barriers and facilitators related to participation, which in turn affect hearing aid use and acceptance, were uncovered. The results of this study have implications for audiologic research, and practice.

Los resultados de este estudio tienen implicaciones para la investigación y la práctica audiológica.     

Investigation of hearing aid users' speech understanding in noise and their spectral-temporal resolution skills

PurposeOur study aims to compare speech understanding in noise and spectral- temporal resolution skills with regard to the degree of hearing loss, age, hearing aid use experience and gender of hearing aid users.MethodsOur study included sixty-eight hearing aid users aged between 40-70 years, with bilateral mild and moderate symmetrical sensorineural hearing loss. Random gap detection test, Turkish matrix test and spectral-temporally modulated ripple test were implemented on the participants with bilateral hearing aids. The test results acquired were compared statistically according to different variables and the correlations were examined.ResultsNo statistically significant differences were observed for speech-in-noise recognition, spectral-temporal resolution among older and younger adults in hearing aid users (p>0.05). There wasn’t found a statistically significant difference among test outcomes as regards different hearing loss degrees (p>0.05). Higher performances were obtained in terms of temporal resolution in male participants and participants with more hearing aid use experience (p<0.05). Significant correlations were obtained between the results of speech-in-noise recognition, temporal resolution and spectral resolution tests performed with hearing aids (p<0.05).ConclusionOur study findings emphasized the importance of regular hearing aid use and it showed that some auditory skills can be improved with hearing aids. Observation of correlations among the speech-in-noise recognition, temporal resolution and spectral resolution tests have revealed that these skills should be evaluated as a whole to maximize the patient's communication abilities.     

An Australian version of the acceptable noise level test and its predictive value for successful hearing aid use in an older population

Abstract

Objective: The acceptable noise level (ANL), a measure of noise tolerance, has been proposed as a predictor for successful hearing aid use. The aims of this study were to obtain normative data, and to evaluate the clinical feasibility and predictive value of an Australian version of the ANL test in an older population. Design: Repeated ANL measurements were presented diotically using earphones. All participants provided demographic information and hearing aid owners were asked about their aid use. Study sample: A total of 290 older adults were assessed; 166 participants had a hearing impairment and 96 owned a hearing aid. Results: The mean ANL was lower than previously reported. While age and gender had no effect on ANL, a significant, but weak, correlation was found between ANL and hearing loss. The test-retest reliability showed the results were clinically unreliable. In addition, the ANL did not predict hours or pattern of hearing aid use. Conclusions: While the Australian ANL test showed several similar characteristics to previous versions of the test, low test-retest reliability raised questions about its clinical value as a predictor for long-term hearing aid use.     

Representations of workers with hearing loss in Canadian newspapers: a thematic analysis

Objective: Participation in the labour force with a hearing impairment presents a number of challenges. This study describes how Canadian newspapers represent workers with hearing loss. Design: Taking a critical framing theory approach, thematic analysis was performed through coding relevant articles, abstracting and hierarchically categorising themes. Study sample: Seven English-language Canadian newspapers were searched for publications between 1995 and 2016. Twenty-six articles met our criteria: discussing paid workers with hearing loss who used English rather than sign language on the job and making reference to workers’ competence. Results: We identified a global theme, Focussing on a good worklife or focussing on a limited worklife, composed of three organising themes (1) Prominent individuals struggle, take action, and continue despite hearing loss, (2) Workers with hearing loss in the community create their best day themselves, and (3) Workers with hearing loss, as a generalised whole, are portrayed as either competent or limited. Conclusions: The dominant framing portrays individual workers as ingenious, determined, and successful. Negative framings were predominantly generalisations to these workers as a group. To generate more positive framings, professionals can build relationships with consumer groups and, when contacted by the media, direct journalists to interview workers with hearing loss.     

The relationship between pre-fitting expectations and willingness to use hearing aids

Hearing-aid use in the elderly population is problematic since not all people who would benefit from hearing aids actually obtain one. In this study, the relationship between pre-fitting expectations and willingness to use hearing aids is addressed.

One hundred adult hearing aid candidates (mean age 68.6 years) were randomly recruited from eight different private ENT practices. The subjects completed a questionnaire comprising a number of different aspects of expectation and some additional variables potentially influencing willingness to use hearing aids. Based on the outcome of the questionnaire a linear regression model predicting motivation to use hearing aids was calculated and evaluated.

Among the 11 parameters evaluated three contributed significantly to the model of willingness. The three predictor variables were expectations towards improvement of quality of life, stigmatization, and self-rated hearing ability. They accounted for about 55% of the variability in the data for willingness. Examination of a sub-sample three months after the survey had taken place revealed a distinct relationship between willingness and the decision to obtain or decline hearing aids.

In conclusion, the results strongly encourage supporting positive expectations in order to motivate individuals with hearing impairment to use hearing systems.

Advantages of binaural hearing provided through bimodal stimulation via a cochlear implant and a conventional hearing aid: A 6-month comparative study

Conclusions

Our study data demonstrate the additional benefit derived from continued use of a contralateral hearing aid (HA) post-cochlear implantation for speech recognition ability in quiet and in noise. Postoperative bimodal stimulation is recommended for all subjects who show some speech recognition ability in the contralateral ear as it may offer binaural listening advantages in various listening situations encountered in everyday life.

Objectives

To assess the benefits derived from bimodal stimulation for experienced HA users implanted with a cochlear implant (CI) (score?≥?20% in disyllabic test). The correlation between pre- and postoperative performance on speech perception measures was examined to determine additional criteria for recommending bimodal stimulation postoperatively.

Material and methods

A within-subject repeated-measures design was used, with each subject acting as their own control. Assessments were carried out preoperatively in aided monaural and best-aided conditions and at 6 months postoperatively in CI-alone, contralateral HA-alone and bimodal listening conditions. Speech recognition using Spanish words and sentences materials was assessed at conversational level and for soft speech in quiet. Speech comprehension in noise was assessed using word materials at a signal:noise ratio of +10, for coincident speech in noise and for spatially separated speech in noise. Twelve adult native Spanish subjects with a severe-to-profound hearing impairment who were experienced with optimally fitted conventional amplification and who displayed suboptimal speech understanding preoperatively were enrolled in the study. Preoperatively, conventional amplification was worn by five subjects binaurally and by seven monaurally.

Results

Postoperatively, superior speech recognition ability in quiet and in noise for disyllabic words was achieved using bimodal stimulation in comparison to performance for either monaural aided condition. Mean improvement in speech recognition in the bimodal condition was significant over performance in the CI-alone condition for disyllabic words in quiet at 70 (p=0.006) and 55 dB SPL (p=0.028), for disyllabic words in noise at +10 dB with speech and noise spatially separated with the noise source closest to the contralateral HA (S0NHA) (p=0.0005) and when the noise source was closest to the CI ear (S0NCI) (p=0.002). When testing word recognition in noise with speech and noise sources coincident in space, word scores were superior in the bimodal condition relative to the CI-alone condition but this improvement was not significant (p=0.07). The advantages of bimodal stimulation included significant effects of binaural summation in quiet and significant binaural squelch effects in both the S0NHA and S0NCI test conditions. All subjects showed superior performance in the binaural situation postoperatively relative to the best-aided condition preoperatively for one or more test situations.
