A recent development in hearing aids, the contralateral routing of signals (CROS), makes it possible to provide amplification for persons with unilateral hearing loss. In 1967, a CROS eyeglass hearing aid was placed on government contract and made available to veterans. To study the efficiency of the CROS, a follow-up questionnaire was sent to 60 male veterans who had been fitted with this aid. All had demonstrated unilateral hearing losses, and the mean threshold for the speech frequencies (500–2000 Hz) in the good ear was 24 dB. The 54 replies (90%) indicated that 85% wore the aid, liked it, and derived benefit from it; 15% neither liked nor wore the aid. The CROS appeared to be most helpful in listening to conversational speech and at work, and most disturbing in a noisy environment. The complaints about the aid fell into major categories: 33% objected to its poor fit and construction and 11% were disturbed by speech distortion. The CROS aid has been a useful addition to the hearing-aid stock at the clinic reported here. It has expanded the program by providing amplification to veterans who could not be fitted with the conventional stock of aids.

The Mean

A total of 190 individuals participated in a clinical visit during the Cooperative Studies Program (CSP) 418-A Long Term Follow-Up Study. Of this cohort, 158 participants were considered current hearing aid users, and 32 were non–hearing aid users. Of the current hearing aid users, 81 were still using their original 418 study devices, and 77 had acquired new hearing aids. Coupler and real ear measurements were completed on all available hearing aids. Results showed that study aids had remained relatively stable over the six years between CSP 418 and CSP 418-A. On average, these hearing aid wearers preferred use gain settings that were 6–9 dB less than current NAL-RP insertion gain targets. Mean real ear insertion gain (REIG) was comparable to the mean real ear insertion gain of the same participants in the original study, and users did not tend to increase gain as hearing decreased. Real ear saturation responses (RESR) remained unchanged. Loudness discomfort levels (LDL) obtained during 418-A were significantly lower than LDLs obtained on those same participants at both the initial and final visits in the previous study. Un total de 190 individuos participaron de la visita clínica durante el Estudio de Seguimiento a Largo Plazo 418-A del Programa de Estudios Cooperativos (CSP). De esta cohorte, 158 participantes se consideraron usuarios actuales de auxiliares auditivos (AA), y 32 se consideraron no usuarios de AA. De los usuarios actuales de AA, 81 aún utilizaban sus dispositivos 418 del estudio, y 77 había adquiridos nuevos AA. Se completaron mediciones de acoplador y de oído real para todos los AA disponibles. Los resultados mostraron que los AA del estudio había permanecido relativamente estables en los seis años entre el CSP 418 y el CSP 418-A. En promedio, estos usuarios de AA prefirieron el uso de ajustes de ganancia que estaban 6-9 dB por debajo de las metas actuales de ganancia de inserción del NAL-RP. La ganancia media de inserción de oído real (REIG) fue comparable con la ganancia media de inserción de oído real de los mismos participantes en el estudio original, y los sujetos no tendieron a incrementar la ganancia conforme la audición se deterioró. Las respuestas de saturación de oído real (RESR) se mantuvieron sin cambio. Los niveles de incomodidad a la intensidad subjetiva (LDL) obtenidos durante el 419-A fueron significativamente más bajos que los LDL obtenidos en los mismos participantes, tanto en la visita inicial como final del estudio previo.

Hearing Aid Benefit

Perceived benefit, satisfaction, and hearing aid use patterns were measured in a follow-up study to a large-scale multi-site clinical trial conducted in 1996–97. Measures included the Hearing Aid Status Questionnaire, the Profile of Hearing Aid Benefit, the Glasgow Hearing Aid Benefit Profile, the Satisfaction with Amplification in Daily Life, and the International Outcome Inventory for Hearing Aids. On the Profile of Hearing Aid Benefit, hearing aid users indicated more unaided difficulty in easy listening situations and less aided benefit in more difficult listening situations compared to the original study. Subjects who no longer used hearing aids indicated less difficulty in unaided situations. All measures indicated significant long-term subjective benefit and satisfaction with hearing aids. Although understanding speech in noise or in group situations continues to be problematic, subjects reported wearing their hearing aids almost all of the time in both easy and difficult listening situations. Se midió el beneficio y la satisfacción del paciente y los patrones de uso del auxiliar auditivo (AA) en un estudio de seguimiento de un estudio clínico, multicéntrico, a larga escala, conducido en 1996–97. Las mediciones incluyeron el Cuestionario del Estado de Uso del Auxiliar Auditivo, el Perfil de Beneficio del Auxiliar Auditivo, El Perfil de Glasgow de Beneficio del Auxiliar Auditivo, la Prueba de Satisfacción con la Amplificación en la Vida Diaria, y el Inventario Internacional de Resultados de Auxiliares Auditivos. En el Perfil de Beneficio de Auxiliares Auditivos, los usuarios de AA indicaron más dificultad sin amplificación en situaciones fáciles de escucha y menor beneficio con amplificación en situaciones difíciles de escucha, comparado con el estudio original. Los sujetos que no volvieron a usar sus AA indicaron menos dificultad en situaciones no amplificadas. Todas las medidas indicaron una satisfacción y un beneficio subjetivo y significativo a largo plazo, con los AA. Aunque entender el lenguaje en ruido o en situaciones grupales continúa siendo problemático, los sujetos reportaron la utilización de sus AA casi todo el tiempo, tanto en situaciones fáciles como difíciles de escucha.

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 Purpose: to investigate speech recognition in silence and in noise in subjects with unilateral hearing loss with and without hearing aids, and to analyze the benefit, self-perception of functional performance, satisfaction and the use of hearing aids in these subjects. Methods: eleven adults with unilateral, mixed and sensorineural, mild to severe hearing loss participated in this study. Speech recognition was evaluated by the Brazilian Portuguese sentences lists test; functional performance of the hearing was assessed by using the Speech Spatial and Qualities of Hearing Scale questionnaire; satisfaction was assessed by the Satisfaction with Amplification in Daily Life questionnaire, both in Brazilian Portuguese; and to assess the use of hearing aids, the patient's report was analyzed. Results: the adaptation of hearing aids provided benefits in speech recognition in all positions evaluated, both in silence and in noise. The subjects did not report major limitations in communication activities with the use of hearing aids. They were satisfied with the use of sound amplification. Most of the subjects did not use hearing aids, effectively. The discontinuity of hearing aids use can be justified by the difficulty on perceiving participation’s restriction caused by hearing loss, as well as the benefit of the hearing aid, besides the concern with batteries’ costs and aesthetic aspects. Conclusion: although showing benefits in speech recognition, in silence and in noise, and satisfaction with sound amplification, most subjects with unilateral hearing loss do not effectively use hearing aids.

The aims of this study were to investigate hearing aid satisfaction for a group of older Australians fitted with government-funded hearing aids using the Satisfaction with Amplification in Daily Life (SADL) questionnaire; to compare the Australian data gathered with the provisional normative data reported by Cox and Alexander (1999); and to investigate the relationship between SADL satisfaction and several participant variables, hearing aid variables, and other outcome measures.The SADL questionnaire and a Client Satisfaction Survey (CSS) were distributed by mail to 1284 adults fitted with government-funded hearing aids three to six months previously. 1014 surveys were returned. The mean age of participants was 75.32 years; 54.4% of participants were male, and 54.8% were fitted binaurally. Participants were fitted primarily with digitally programmable hearing aids of various styles (22.5% BTEs, 34.8% ITEs, 41.8% ITCs, 0.9% nonstandard [NS] devices).Overall, participants reported a considerable level of satisfaction with their devices. SADL Global and subscale scores were significantly higher for the Australian sample than the U.S. norms described by Cox and Alexander (1999).

Background: Despite clinical recognition of the adverse effects of acquired hearing loss, only a small proportion of adults who could benefit use hearing aids. Hearing aid adoption has been studied in relationship to client-related and hearing aid technology–related factors. The influence of the client-clinician interaction in the decision to purchase hearing aids has not been explored in any depth. Purpose: Importance ratings of a sample of adults having a recent hearing aid recommendation (clients) and hearing healthcare professionals (clinicians) from across Canada were compared on factors in client-clinician interactions that influence hearing aid purchase decisions. Research Design: A cross-sectional approach was used to obtain online and paper-based concept ratings. Data Collection and Analysis: Participants were 43 adults (age range, 45–85 yr) who had received a first hearing aid recommendation in the 3 mo before participation. A total of 54 audiologists and 20 hearing instrument practitioners from a variety of clinical settings who prescribed or dispensed hearing aids completed the concept-rating task. The task consisted of 122 items that had been generated via concept mapping in a previous study and which resulted in the identification of eight concepts that may influence hearing aid purchase decisions. Participants rated “the importance of each of the statements in a person’s decision to purchase a hearing aid” on a 5-point Likert scale, from 1 = minimally important to 5 = extremely important. For the initial data analysis, the ratings for each of the items included in each concept were averaged for each participant to provide an estimate of the overall importance rating of each concept. Multivariate analysis of variance was used to compare the mean importance ratings of the clients to the clinicians. Ratings of individual statements were also compared in order to investigate the directionality of the importance ratings within concepts. Results: There was a significant difference in the mean ratings for clients and clinicians for the concepts understanding and meeting client needs, conveying device information by clinician, supporting choices and shared decision making, and factors in client readiness. Three concepts—understanding and meeting client needs, conveying device information by clinician, and supporting choices and shared decision making—were rated as more important by clients than by clinicians. One concept (ie, factors in client readiness) was rated as more important by clinicians than by clients. Conclusions: The concepts rated as most important by clients and clinicians are consistent with components of several existing models of client-centered and patient-centered care. These concepts reflect the clients’ perception of the importance of their involvement in the decision-making process. A preliminary model of client-centered care within the hearing aid uptake process and implications for clinical audiology are described.

Multilevel Cervical Spondylotic Myelopathy

The laminoplasty technique was devised by Hirabayashi in 1978 for patients diagnosed with multilevel cervical spondylotic myelopathy. Objective: To describe an easy modification of Hirabayashi’s method and present the clinical and radiological results from a five-year follow-up study. Method and Results: Eighty patients had 5 levels of decompression (C3-C7), 3 patients had 6 levels of decompression (C2-T1) and 3 patients had 4 levels of decompression (C3-C6). Foraminotomies were performed in 23 cases (27%). Following Nurick`s scale, 76 patients (88%) improved, 9 (11%) had the same Nurick grade, and one patient worsened and was advised to undergo another surgical procedure. No deaths were observed. The mean surgery time was 122 min. Radiographic evaluation showed an increase in the mean sagittal diameter from 11.2 mm at pretreatment to 17.3 mm post surgery. There was no significant difference between pretreatment and post-surgery C2-C7 angles. Conclusions: This two-open-doors laminoplasty technique is safe, easy and effective and can be used as an alternative treatment for cases of multilevel cervical spondylotic myelopathy without instability.

Cortical Auditory Evoked Potentials

Background. Functioning of nonlinear hearing aids varies with characteristics of input stimuli. In the past decade, aided speech evoked cortical auditory evoked potentials (CAEPs) have been proposed for validation of hearing aid fittings. However, unlike in running speech, phonemes presented as stimuli during CAEP testing are preceded by silent intervals of over one second. Hence, the present study aimed to compare if hearing aids process phonemes similarly in running speech and in CAEP testing contexts.Method. A sample of ten hearing aids was used. Overall phoneme level and phoneme onset level of eight phonemes in both contexts were compared at three input levels representing conversational speech levels.Results. Differences of over 3 dB between the two contexts were noted in one-fourth of the observations measuring overall phoneme levels and in one-third of the observations measuring phoneme onset level. In a majority of these differences, output levels of phonemes were higher in the running speech context. These differences varied across hearing aids.Conclusion. Lower output levels in the isolation context may have implications for calibration and estimation of audibility based on CAEPs. The variability across hearing aids observed could make it challenging to predict differences on an individual basis.

Changes in self-perceptions of fitness, appearance, and self-esteem among adolescents were assessed in a 4-year follow-up study. Both the changes in the mean levels across time (profile analysis), and the changes in the reliability and stability of individual differences (i.e. covariance stability as test-retest correlations) were examined. The subjects (64 boys, 49 girls) were 11 years old at the first annual measurement. Self-esteem was assessed using the Rosenberg Self-Esteem Scale, as well as self-assessment questionnaires specifically designed for this study to assess Perceived Fitness and Perceived Appearance. MANOVA-and Simplex-models were used in the analysis. Our results among the girls were in accordance with the gradual consolidation hypothesis, so that self-perceptions become more fixed with increasing age. The boys showed highly stable self-perceptions throughout the follow-up, which may indicate the early emergence of a fixed self-concept. Self-esteem increased with age but changes in perceived fitness were small over time. The decrease in perceived appearance found among the girls but not among the boys was in accordance with the gender intensification hypothesis.
