Abstract The aim of the study was to develop an algorithm for the interaction between an audiologist and speech-language therapist in initial amplification for hearing impaired children. Methods. 219 children aged 2 months to 16 years with hearing impairments were divided into 2 groups. The experimental group consisted of children who got a special course of medical, psychological and pedagogical rehabilitation at the stage of initial fitting, based on the new algorithm of interdisciplinary interaction between an audiologist and a speech-language therapist. The control group included children with traditional procedure of hearing aids fitting, in which the audiologist didnt interact with the speech therapist. Results. An algorithm for the interaction of an audiologist and speech-language therapist included 3 stages of hearing aids fitting (preparation, initial fitting, adaptation and fine tuning of hearing aids), the tasks of each specialist at these stages were identified, including the parents involvement in the process of fitting, a development of the protocol for the exchange of information between specialists. The algorithm was implemented in a special course of medical-psychological-pedagogical rehabilitation in the Center of Pediatric Audiology. It was found that in 1 month after the primary fitting among children who underwent this course, significantly more children used hearing aids for more than 8 hours a day and reached the integral criterion of effective hearing aids fitting compared with the control group. These children also took less time to adjust their hearing aid settings during repeated fitting sessions. Conclusion. A structured interdisciplinary interaction between an audiologist and speech-language therapist at the stage of initial amplification significantly increases the effectiveness of medical technology for restoring hearing function in children.

The project is situated in the field of teaching physics, generally speaking, science education. It aims at studying the interplay between physics and mathematics, introducing an interdisciplinary approach based on the modern concept of symmetry or sameness within change (i.e., invariance). The interdisciplinary methods integrate the process skills common to discovery-based science and problem-based mathematics, typically of Nature of Science (NoS) modelling. We designed a teaching-learning sequence(TLS) and implemented it in an Italian primary school on a sample group (N = 96). Research conforms to pre-and post-test design with a control group. The resulting data were examined through a mixed method. We assess the effectiveness of the TLS by analysing the learning changes in the level of pupils’ knowledge of symmetry. The findings show that the pupils were in the regime of competence for grasping the changed view of symmetry. It also provides ideas that the concepts of symmetry and invariance will allow building the architecture of more extensive scientific knowledge. The study of transformations and invariants facilitates the acquisition of cognitive procedures fitting in many domains, modelling and generalization processes. This research contribution brings important suggestions for designs of successive steps in the learning path on symmetry.

Test Analysis

This pilot study was designed to examine the effects of either providing or withholding subject-driven, postfitting electroacoustic changes (fine tuning) on hearing aid performance as measured by tests of speech recognition in noise, sound quality, and benefit. A group of adult first-time hearing aid users with moderate, high-frequency sensorineural hearing loss was studied over a 5-month postfitting period. Half of the group served as a control group; half constituted the treatment group. Treatment consisted of making as many postfitting electroacoustic manipulations as the participants’ complaints/observations required. These adjustments were withheld from the control group individuals. Group performance differences were assessed using the COSI, two versions of the APHAB, a Satisfaction scale, a Sound Quality tool, and the SIN test. Analysis revealed no statistically significant differences in the control and treatment groups’ performances or perceived benefit at any of the five postfitting test sessions. These data suggested that there was no measurable advantage to be derived from making postfitting frequency-gain adjustments of 10 dB or less to hearing aids with wide dynamic range compression fitted in the manner described in this article. Definitive studies of the effects of postfitting electroacoustic fine tuning must be undertaken.

The Impact

Abstract Background Hearing loss is quite prevalent and can be related to people’s quality of life. To our knowledge, there are limited studies assessing the efficacy of hearing interventions on quality of life in adults. Therefore, we aim to conduct a randomized controlled trial (RCT) to determine the impact and cost-effectiveness of community-based hearing rehabilitation on quality of life among Chinese adults with hearing loss. Methods/design In this two-arm feasibility study, participants aged 16 and above with some degree of hearing loss (n = 464) will be recruited from Linyi City, Shandong Province. They are randomly assigned to the treatment group or the control group. Those in the treatment group are prescribed with hearing aids, while those in the control group receive no intervention. Reinstruction in use of devices is provided for the treatment group during booster visits held 12 months post-randomization or unscheduled interim visits when necessary. Data are collected at baseline and the follow-up 20 months later. The primary outcome is changes in quality of life over a 20-month study period. Secondary outcomes include sub-dimensions in quality of life, physical functioning, chronic diseases, cognitive function, depression, social support, hospitalizations, falls, and healthcare costs. Finally, we will evaluate whether hearing aids intervention is cost-effective to apply in a large scale. Discussion The trial is designed to evaluate the impact and cost-effectiveness of a community-based rehabilitation intervention on quality of life among Chinese adults with hearing loss. We hope that it would help improve the well-being for Chinese adults and provide references in policy and practice for China and other countries.

Age Related Hearing Loss

Age-related hearing loss (ARHL), a sensorineural hearing loss of multifactorial origin, increases its prevalence in aging societies. Besides hearing aids and cochlear implants, there is no FDA approved efficient pharmacotherapy to either cure or prevent ARHL. We hypothesized that selegiline, an antiparkinsonian drug, could be a promising candidate for the treatment due to its complex neuroprotective, antioxidant, antiapoptotic, and dopaminergic neurotransmission enhancing effects. We monitored by repeated Auditory Brainstem Response (ABR) measurements the effect of chronic per os selegiline administration on the hearing function in BALB/c and DBA/2J mice, which strains exhibit moderate and rapid progressive high frequency hearing loss, respectively. The treatments were started at 1 month of age and lasted until almost a year and 5 months of age, respectively. In BALB/c mice, 4 mg/kg selegiline significantly mitigated the progression of ARHL at higher frequencies. Used in a wide dose range (0.15–45 mg/kg), selegiline had no effect in DBA/2J mice. Our results suggest that selegiline can partially preserve the hearing in certain forms of ARHL by alleviating its development. It might also be otoprotective in other mammals or humans.

Blinding of the participants and facilitator was not possible.ResultsTwelve hearing aid users and six significant others consented to take part. Eight hearing aid users were randomised: four to the intervention group; and four to treatment-as-usual only. Four significant others participated alongside the randomised participants. Recruitment to the study was very low and centres only screened 466 hearing aid users over the 15-month recruitment period, compared with the approximately 3500 anticipated. Only one ACE group and one control group were formed. ACE could be delivered and appeared acceptable to participants. We were unable to robustly assess attrition and attendance rates due to the low sample size.ConclusionsWhile ACE appeared acceptable to hearing aid users and feasible to deliver, it was not feasible to identify and recruit participants struggling with their hearing aids at the 3-month posthearing aid fitting point.Trial registration numberISRCTN28090877.

Unrealistic Expectations

Background: Data suggest that having high expectations about hearing aids results in better overall outcome. However, some have postulated that excessively high expectations will result in disappointment and thus poor outcome. It has been suggested that counseling patients with unrealistic expectations about hearing aids prior to fitting may be beneficial. Data, however, are mixed as to the effectiveness of such counseling, in terms of both changes in expectations and final outcome. Purpose: The primary purpose of this study was to determine whether supplementing prefitting counseling with demonstration of real-world listening can (1) alter expectations of new hearing aid users and (2) increase satisfaction over verbal-only counseling. Secondary goals of the study were to examine (1) the relationship between prefitting expectations and postfitting outcome, and (2) the effect of hearing aid fine-tuning on hearing aid outcome. Research Design: Sixty new hearing aid users were fitted binaurally with Beltone Oria behind-the-ear digital hearing aids. Forty participants received prefitting counseling and demonstration of listening situations with the Beltone AVE™ (Audio Verification Environment) system; 20 received prefitting counseling without a demonstration of listening situations. Hearing aid expectations were measured at initial contact and following prefitting counseling. Reported hearing aid outcome was measured after eight to ten weeks of hearing aid use. Study Sample: Sixty new hearing aid users aged between 55 and 81 years with symmetrical sensorineural hearing loss. Intervention: Participants were randomly assigned to one of three experimental groups, between which the prefitting counseling and follow-up differed: Group 1 received prefitting counseling in combination with demonstration of listening situations. Additionally, if the participant had complaints about sound quality at the follow-up visit, the hearing aids were fine-tuned using the Beltone AVE system. Group 2 received prefitting counseling in combination with demonstration of listening situations with the Beltone AVE system, but no fine-tuning was provided at follow-up. Group 3 received prefitting hearing aid counseling that did not include demonstration of listening, and the hearing aids were not fine-tuned at the follow-up appointment. Results: The results showed that prefitting hearing aid counseling had small but significant effects on expectations. The two forms of counseling did not differ in their effectiveness at changing expectations; however, anecdotally, we learned from many participants that that they enjoyed listening to the auditory demonstrations and that they found them to be an interesting listening exercise. The data also show that positive expectations result in more positive outcome and that hearing aid fine-tuning is beneficial to the user. Conclusions: We conclude that prefitting counseling can be advantageous to hearing aid outcome and recommend the addition of prefitting counseling to address expectations associated with quality of life and self-image. The data emphasize the need to address unrealistic expectations prior to fitting hearing aids cautiously, so as not to decrease expectations to the extent of discouraging and demotivating the patient. Data also show that positive expectations regarding the impact hearing aids will have on psychosocial well-being are important for successful hearing aid outcome.

Abstract Background Cartilage conduction hearing aids (CCHAs) were newly devised and spread fast in Japan since their launch in 2017. However, little knowledge is available for this new device. Purpose The aim of this study was to establish the knowledge of CCHAs and suggest their indication. Research Design Correlational study. Study Sample A total 256 patients were registered. Data Collection and Analysis The fitting of CCHAs was surveyed in nine institutions. The outcomes were assessed by audiometric tests. The patients were classified into seven groups, depending on the ear conditions. The clinical characteristics, assessment results, and purchase rates were compared among the groups. The assessment results of CCHAs were also compared with those of previously used hearing aids. Results Most patients who used CCHAs were classified into the bilateral closed (aural atresia or severe stenosis) ear (n = 65) or unilateral closed ear (n = 124) groups. The patients in these groups achieved good benefits that resulted in a high purchase rate. The bilateral continuous otorrhea group also supported a high purchase rate, although the benefits of CCHAs were not always excellent. In contrast, the purchase rate was poor in the patients who could use air conduction hearing aids (ACHAs) without absolute problems. As for using a CCHA as a contralateral routing of signals hearing aid, the benefits depended on the patients. Conclusions CCHAs are considered as a great option not only to the patients with closed ears but also to those who had difficulties in ACHAs usage.

The objective: was to optimize the treatment of patients with post-stress disorders of menstrual function by conducting pathogenetic complex therapy from the perspective of an interdisciplinary approach. Materials and methods. 54 women aged 19-37 years with psychogenic amenorrhea (PA) – the main group – were examined. The control group included 25 practically healthy patients aged 18 to 35 years. Results. The variants of hormonal disorders in this pathology are determined, the analysis of the results of electroencephalography and the study of individual and reactive anxiety in patients with PA are performed. The presence of three pathogenetic variants of hormonal disorders was established, which became the criterion of the proposed differentiated pathogenetic treatment. Conclusion. Features of the pathogenesis of psychogenic amenorrhea, the complexity of neuroendocrine and hormonal disorders indicate the need for an interdisciplinary approach in the examination, treatment and rehabilitation of this category of patients with the involvement of related specialists – a neurologist and psychotherapist.

Background: Although guidelines for fitting hearing aids for children are well developed and have strong basis in evidence, specific protocols for fitting and verifying technologies can supplement such guidelines. One such technology is frequency-lowering signal processing. Children require access to a broad bandwidth of speech to detect and use all phonemes including female /s/. When access through conventional amplification is not possible, the use of frequency-lowering signal processing may be considered as a means to overcome limitations. Fitting and verification protocols are needed to better define candidacy determination and options for assessing and fine tuning frequency-lowering signal processing for individuals. Purpose: This work aims to (1) describe a set of calibrated phonemes that can be used to characterize the variation in different brands of frequency-lowering processors in hearing aids and the verification with these signals and (2) determine whether verification with these signal are predictive of perceptual changes associated with changes in the strength of frequency-lowering signal processing. Finally, we aimed to develop a fitting protocol for use in pediatric clinical practice. Study Sample: Study 1 used a sample of six hearing aids spanning four types of frequency lowering algorithms for an electroacoustic evaluation. Study 2 included 21 adults who had hearing loss (mean age 66 yr). Data Collection and Analysis: Simulated fricatives were designed to mimic the level and frequency shape of female fricatives extracted from two sources of speech. These signals were used to verify the frequency-lowering effects of four distinct types of frequency-lowering signal processors available in commercial hearing aids, and verification measures were compared to extracted fricatives made in a reference system. In a second study, the simulated fricatives were used within a probe microphone measurement system to verify a wide range of frequency compression settings in a commercial hearing aid, and 27 adult listeners were tested at each setting. The relation between the hearing aid verification measures and the listener’s ability to detect and discriminate between fricatives was examined. Results: Verification measures made with the simulated fricatives agreed to within 4 dB, on average, and tended to mimic the frequency response shape of fricatives presented in a running speech context. Some processors showed a greater aided response level for fricatives in running speech than fricatives presented in isolation. Results with listeners indicated that verified settings that provided a positive sensation level of /s/ and that maximized the frequency difference between /s/ and /∫/ tended to have the best performance. Conclusions: Frequency-lowering signal processors have measureable effects on the high-frequency fricative content of speech, particularly female /s/. It is possible to measure these effects either with a simple strategy that presents an isolated simulated fricative and measures the aided frequency response or with a more complex system that extracts fricatives from running speech. For some processors, a more accurate result may be achieved with a running speech system. In listeners, the aided frequency location and sensation level of fricatives may be helpful in predicting whether a specific hearing aid fitting, with or without frequency-lowering, will support access to the fricatives of speech.
