    ABSTRACT: Objective: To investigate audiological and quality of life outcomes for a new active transcutaneous device, called the bone conduction implant (BCI), where the transducer is implanted under intact skin. Design: A clinical study with sound field audiometry and questionnaires at six-month follow-up was conducted with a bone-anchored hearing aid on a softband as reference device. Study sample: Six patients (age 18-67 years) with mild-to-moderate conductive or mixed hearing loss. Results: The surgical procedure was found uneventful with no adverse events. The first hypothesis that BCI had a statistically significant improvement over the unaided condition was proven by a pure-tone-average improvement of 31.0 dB, a speech recognition threshold improvement in quiet (27.0 dB), and a speech recognition score improvement in noise (51.2 %). At speech levels, the signal-to-noise ratio threshold for BCI was - 5.5 dB. All BCI results were better than, or similar to the reference device results, and the APHAB and GBI questionnaires scores showed statistically significant improvements versus the unaided situation, supporting the second and third hypotheses. Conclusions: The BCI provides significant hearing rehabilitation for patients with mild-to-moderate conductive or mixed hearing impairments, and can be easily and safely implanted under intact skin.

    ABSTRACT: Objective: To evaluate the impact of non-adaptive matched and mismatched gain reduction schemes on localization in spatially-separated noise. Design: Inspired by the function of commercial noise reduction algorithms, five frequency-specific gain reduction filter schemes were created, three for a modulated babble-noise and two for an unmodulated speech-shaped noise. Applying these schemes as both matched and mismatched conditions across ears, localization of five everyday sounds in noise was measured in a virtual environment using insert earphones. The performance in the reference scheme (no gain reduction in either ear) was measured as well. Study sample: Twenty-four adult bilateral hearing-aid users were enrolled in this study. Results: One of the two mismatched gain reduction schemes for the unmodulated noise had a small but negative impact on localization compared to the reference scheme. For that scheme more high-frequency reduction was noted than for the other schemes. Matching gain reduction across ears restored the deteriorated localization performance. No localization performance differences were observed in the modulated babble-noise regardless of whether the scheme was matched or mismatched across ears. Conclusions: The impact of noise-induced gain reduction on localization in noise was trivial in the study regardless of whether gain reduction schemes were matched or not across ears.

    ABSTRACT: Objective: The objective of this study was to test if stimulating multiple electrodes can improve temporal pitch ranking performance at low and high stimulation rates. Design: Temporal pitch cues are usually based on modifying the stimulation rate of the implant and thereby provide a continuum of pitches on a single electrode up to approximately 300 Hz. Study sample: Ten cochlear implant subjects were asked to pitch rank stimuli presented with direct electrical stimulation. The pulses were applied on one, three, six, or eleven electrodes. In one of the conditions the current amplitude of each pulse was randomly varied between 0 and 100%. Their frequency ranged from 100 up to 500 pps. Results: Listeners showed the previously reported performance pattern in most conditions with very good performance at the lowest standard rates and deteriorating performance to near chance level at the highest rate tested. Performance with eleven electrodes was signifi cantly better than performance with one electrode at 500 pps. Conclusion: Stimulating on multiple electrodes can improve temporal pitch perception.

    ABSTRACT: Objective: To explore the impact, reactions and coping methods of the significant others (SOs) of people with Ménière's disease (MD). Design: SOs of people with MD were asked to answer open-ended questions reporting the 'life effects' and 'positive experiences' they have had as a result of the partner's condition. The replies to the 'life effects' question was categorized using the WHO-ICF framework. The responses of 'life effects' from this study and the 'positive experiences' reported in a recent study ( Manchaiah et al, 2013 ) were evaluated with K-means clustering analysis. Study sample: Eighty-eight SOs (42 male, 42 female, and four did not state gender). Results: While the SOs mainly listed their own problems, a significant number of responses related to the problems of their partner. Personal perspectives tended to focus on the consequences of their partner's condition, whereas in perspectives of their partner they focussed on his/her symptoms. Further, replies from 81 SOs were used in evaluation of responses and were classified into four categories: constrained life attitude; disease burden attitude; care and support attitude; and social isolation attitude. Conclusions: The results of this study support the importance of including the SO of people with MD in the rehabilitation process.

    ABSTRACT: Objective: A clinical description of post-traumatic benign paroxysmal positional vertigo (t-BPPV) in a large cohort is reported, sometimes caused by apparently insignificant minor head traumas. The aim of the study was to carefully assess the prevalence of t-BPPV and the main outcomes belonging to specific traumatic events. Design: Retrospective analysis of medical records of t-BPPV cases among patients suffering from BPPV. Study sample: Among 3060 patients with a clinical diagnosis of BPPV, we reviewed 716 clinical cases in which a clear association to a traumatic event was present. Results: A traumatic event was identified in 23.4% of total enrolled BPPV patients. Some minor head traumas could be more prone to determine BPPV in females. We confirmed that t-BPPV appeared significantly more difficult to treat than idiopathic form. Posterior canal t-BPPV cases required more treatment sessions before obtaining therapeutic success, while horizontal ones recovered at most after two repositioning maneuvers. Conclusion: Post-traumatic BPPV is considered one of the most common known etiologies. An accurate understanding of trauma mechanism, gender prevalence, and therapeutic success rates of each event, could be useful in adequately treating and planning follow-up examinations.

    ABSTRACT: Abstract Objective: To develop and apply a pedagogical method focusing on Empowerment, Empathy, Competence, and Counselling: the EC programme, and to present an initial evaluation. The EC programme was gradually developed within a study circle framework and in dialogue with study circle leaders and participants (clients) with hearing impairment (HI). An evaluation was carried out with the study circle leaders. Seventeen upper secondary school students with HI took part in the development of the programme. Eighteen study circle leaders responded to a questionnaire. The EC programme developed consisted of films, CD, and DVD productions to increase insight into one's own hearing ability, to demonstrate for others what HI means, strategies to evaluate situations, and help to act constructively in social situations. The study circle leaders found most of the course material appropriate and easy to use, as a whole or in parts. The leaders' evaluations indicated that the clients had increased their knowledge about how the HI affected themselves and others. The clients had improved their self-confidence and their empathic view of others. The EC programme can be used in its entirety or in part. Participation may lead to increased empowerment, empathy, competence and counselling ability.

    ABSTRACT: Abstract Objective: Auditory processing disorder patients may have deficits in auditory temporal resolution. This study explored: (1) the ear specific norms for young adults using the adaptive tests of temporal resolution (ATTR); (2) the reliability of ATTR using two different modes of stimuli presentation; and (3) the concurrent validity of ATTR with reference to the gaps-in-noise (GIN) test. GIN and ATTR were administered through a standard audiometer and headphones. As ATTR can also be completed using a computer with commercially available headphones, thresholds from these two variants were compared. Thirty normal-hearing young adults were recruited. The mean ATTR gap detection thresholds (GDTs) derived under audiometer administration were 4.60 ms (SD 1.49) and 4.97 ms (SD 1.98) for the left and right ear, respectively. The approximated threshold (A. th.), an equivalent measure to the GDT in the GIN, mean values were 5.37 ms (SD 0.98) and 5.33 ms (SD 1.07) for left and right ears, respectively. No significant threshold difference was found between the ATTR variants. A positive, moderate correlation was found, and Bland-Altman plot analysis revealed good agreement, between GDT and A.th. ATTR and GIN results were moderately associated. Moreover, the ATTR was found to have high test-retest reliability and high specificity for the current participants.

    ABSTRACT: Objective: Specific computer-based auditory training may be a useful completion in the rehabilitation process for cochlear implant (CI) listeners to achieve sufficient speech intelligibility. This study evaluated the effectiveness of a computerized, phoneme-discrimination training programme. Design: The study employed a pretest-post-test design; participants were randomly assigned to the training or control group. Over a period of three weeks, the training group was instructed to train in phoneme discrimination via computer, twice a week. Sentence recognition in different noise conditions (moderate to difficult) was tested pre- and post-training, and six months after the training was completed. The control group was tested and retested within one month. Study sample: Twenty-seven adult CI listeners who had been using cochlear implants for more than two years participated in the programme; 15 adults in the training group, 12 adults in the control group. Results: Besides significant improvements for the trained phoneme-identification task, a generalized training effect was noted via significantly improved sentence recognition in moderate noise. No significant changes were noted in the difficult noise conditions. Improved performance was maintained over an extended period. Conclusions: Phoneme-discrimination training improves experienced CI listeners' speech perception in noise. Additional research is needed to optimize auditory training for individual benefit.

    ABSTRACT: Objective: To investigate the influence of cardiovascular diseases on hearing impairment (HI) among adults. Furthermore, to seek other potential risk factors for HI, such as smoking, obesity, and socioeconomic class. Design: A cross-sectional, unscreened, population-based, epidemiological study among adults. Study sample: The subjects (n = 850), aged 54–66 years, were randomly sampled from the population register. A questionnaire survey, an otological examination, and pure-tone audiometry were performed. Results: Cardiovascular diseases did not increase the risk for HI in a propensity-score adjusted logistic regression model: OR 1.24, 95% CI 0.79 to 1.96 for HI defined by better ear hearing level (BEHL), and OR 1.48, 95% CI 0.96 to 2.28 for HI defined by worse ear hearing level (WEHL), in the 0.5–4 kHz frequency range. Heavy smoking is a risk factor for HI among men (BEHL: OR 1.96, WEHL: OR 1.88) and women (WEHL: OR 2.4). Among men, obesity (BEHL, OR 1.85) and lower socioeconomic class (BEHL: OR 2.79, WEHL: OR 2.28) are also risk factors for HI. Conclusion: No significant association between cardiovascular disease and HI was found.

    ABSTRACT: Objective: To determine if training with electronically-modulated hearing protection (EMHP) and the open ear results in auditory learning on a horizontal localization task. Design: Baseline localization testing was conducted in three listening conditions (open-ear, in-the-ear (ITE) EMHP, and over-the-ear (OTE) EMHP). Participants then wore either an ITE or OTE EMHP for 12, almost daily, one-hour training sessions. After training was complete, participants again underwent localization testing in all three listening conditions. A computer with a custom software and hardware interface presented localization sounds and collected participant responses. Study sample: Twelve participants were recruited from the student population at Virginia Tech. Audiometric requirements were 35 dBHL at 500, 1000, and 2000 Hz bilaterally, and 55 dBHL at 4000 Hz in at least one ear. Results: Pre-training localization performance with an ITE or OTE EMHP was worse than open-ear performance. After training with any given listening condition, including open-ear, performance in that listening condition improved, in part from a practice effect. However, post-training localization performance showed near equal performance between the open-ear and training EMHP. Auditory learning occurred for the training EMHP, but not for the non-training EMHP; that is, there was no significant training crossover effect between the ITE and the OTE devices. Conclusion: It is evident from this study that auditory learning (improved horizontal localization performance) occurred with the EMHP for which training was performed. However, performance improvements found with the training EMHP were not realized in the non-training EMHP. Furthermore, localization performance in the open-ear condition also benefitted from training on the task.

    ABSTRACT: Objective: To determine the usage and knowledge of safe limits on personal listening devices (PLD) among college students. Design: First, information on health history was collected. Second, microphone in real ear techniques determined eardrum to free-field correction factors. Third, hearing levels were evaluated and information gathered about knowledge of safe listening behaviors. Study sample: 180 college students participated in a one-hour session using their PLDs and earphones set to their personal preference. Results: Virtually all participants reported knowledge of hearing loss risk due to PLD use and accurately recognized their own PLD listening levels (p = .01) as either within or exceeding safe sound limits. Forty-four subjects listened at greater than 80-dBA free-field equivalent levels. Only 7% of these participants were aware of these hazardous levels and 15% of participants' exposure surpassed free-field equivalent levels normalized to eight hours. Conclusions: Despite reported knowledge of hearing loss risk due to PLD use in virtually all college students, 1 in 4 were found to listen to their PLDs at free-field equivalent levels greater than 80-dBA, with 94% unaware of their potential risk. Further research is needed to provide accurate PLD listening information and evaluate the possibility of long term PLD intensities that surpass recommended safety levels on hearing loss in adults over time.

    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.

    ABSTRACT: Objective: Study groups from three age cohorts of 70-75 year-olds were investigated to search for possible correlations between dietary habits and auditory function. Design: A cross-sectional, epidemiological study. Study sample: A total number of 524 people (275 women, 249 men) were recruited from three age cohorts. The study sample was representative of the general population. All participants answered a diet history and were tested with pure-tone audiometry. Eleven categories of food consumption were related to pure-tone averages of low-mid frequency hearing, and high frequency hearing. Results: Two consistent correlations between diet and hearing were observed. One was a correlation between good hearing and a high consumption of fish in the male group. The other was a correlation between poor high frequency hearing and a high consumption of food rich in low molecular carbohydrates in both genders; a larger effect size was seen in females. Conclusions: The study indicates that diet is important for aural health in aging. According to this study fish is beneficial to hearing, whereas consumption of "junk food", rich in low molecular carbohydrates, is detrimental. Other correlations, e.g. between high consumption of antioxidants, were not demonstrated here, but cannot be excluded.

    ABSTRACT: Objective: To determine the relative contributions of tinnitus, asymmetrical hearing loss, low frequency hearing loss (pure tone average of 0.5, 1, 2, 3 kHz; PTA.5123), or high frequency hearing loss (pure tone average of 4, 6 kHz; PTA46), to acute injury risk among a cohort of production and maintenance workers at six aluminum manufacturing plants, adjusting for ambient noise exposure and other recognized predictors of injury risk. Design: Retrospective analysis. Study sample: The study considered 9920 workers employed during 2003 to 2008. The cohort consisted of 8818 workers (89%) whose complete records were available. Results: Adjusting for noise exposure and other recognized injury predictors, a 25% increased acute injury risk was observed among workers with a history of tinnitus in conjunction with high-frequency hearing loss (PTA46). Low frequency hearing loss may be associated with minor, yet less serious, injury risk. We did not find evidence that asymmetry contributes to injury risk. Conclusion: These results provide evidence that tinnitus, combined with high-frequency hearing loss, may pose an important safety threat to workers, especially those who work in high-noise exposed environments. These at risk workers may require careful examination of their communication and hearing protection needs.

    ABSTRACT: Objective: The purpose of this study is to determine the relationship between occupational exposures and hearing among elderly Latino Americans. Design: A descriptive, correlational design used for this secondary analysis with the data from the Sacramento Area Latino Study of Aging (SALSA). Study sample: A total of 547 older adults were included. Results: A majority of participants (58%) reported occupational exposures to loud noise and/or ototoxic chemicals. About 65% and over 90% showed hearing loss at low and high frequencies, respectively. Participants with occupational exposure to loud noise and/or ototoxic chemicals were, significantly, two times more likely to have hearing loss at high frequencies compared to those without exposure (OR = 2.29; 95% CI: 1.17 = 4.51, p = .016), after controlling for other risk factors of hearing loss such as age, gender, household income, current smoking, and diabetes. However, lifelong occupational exposure was not significantly associated with hearing loss at low frequencies (OR = 1.43; 95% CI: 0.94 = 2.18, p = .094). Conclusion: Lifelong occupational exposure to loud noise and/or ototoxic chemicals was significantly associated with hearing loss among elderly Latino Americans. Healthy work life through protection from harmful auditory effects of occupational exposures to noise and chemicals will have a positive impact on better hearing in later life.

    ABSTRACT: Objective: To investigate the effect of a break in music exposure on temporary threshold shifts. Design: A cross-over design where subjects are exposed to dance music for either two hours consecutively, or exposed to two hours of dance music with a one-hour break in between. Outcome measure was the change in hearing threshold, measured in 1-dB steps at different time points after ending the music. Study sample: Eighteen normal-hearing subjects participated in this study. Results: Changes in pure-tone threshold were observed in both conditions and were similar, regardless of the break. Threshold shifts could be averaged for 1000, 2000, and 4000 Hz. The shift immediately after the ending of the music was 1.7 dB for right ears, and 3.4 dB for left ears. The difference between left and right ears was significant. One hour after the exposure, right ears were recovered to baseline conditions whereas left ears showed a small but clinically irrelevant remaining shift of approximately 1 dB. Conclusions: The advice to use chill-out zones is still valid, because this helps to reduce the duration to the exposure. This study does not provide evidence that a rest period gives an additional reduction of temporary threshold shifts.

    ABSTRACT: Objective: To propose and evaluate a new method for assessing the potential impact on speech intelligibility when wearing a hearing protection device (HPD) in a noisy environment. Design: The method is based on a self adaptive method for finding the speech reception threshold (SRT) using speech material from the Callsign acquisition test (CAT) presented at a constant level while adjusting the level of a background noise. A key point is to primarily examine the impact of the HPD; i.e. the difference between occluded and unoccluded SRTs, presented as the speech intelligibility impact level. Study sample: A total of 31 test subjects. Results: The method is shown to be stable, with a minimum amount of learning effect, and capable of detecting differences between hearing protection devices. It is also shown that low-attenuation passive HPDs are likely to have a very small effect on speech intelligibility in noise, and that an electronic HPD with a level-dependant function has the potential to improve intelligibility. Conclusions: The results are encouraging regarding the precision, repeatability, and applicability of the proposed method.
