Individuals with unilateral hearing loss of severe-profound degree face listening difficulties while localizing a sound source and while perceiving speech in the presence of noise. The objective was to compare the efficacy of the digitally programmable bone anchored hearing aid (BAHA), trimmer digital BAHA and the transcranial contralateral routing of signal (T-CROS) in improving the listening performance in adults with unilateral hearing loss. Twenty-four adults with unilateral hearing loss was assessed for sound field thresholds, speech perception performance in quiet and noise (direct and indirect conditions) and the subjective quality rating of speech in unaided and aided with either T-CROS or digitally programmable BAHA or trimmer digital BAHA attached to the headband. Results indicated that the participants performed better with both the digitally programmable and the trimmer digital BAHA than the T-CROS in both quiet and noise. However, the digitally programmable BAHA performed better when the speech arrived from the poorer ear side. The current study helps in prioritizing the hearing amplification devices for the trial and also helps in arriving at the appropriate hearing amplification device for the individuals with unilateral hearing loss.

Auditory Performance

Purpose The purpose of this study was to characterize spatial hearing abilities of children with longstanding unilateral hearing loss (UHL). UHL was expected to negatively impact children's sound source localization and masked speech recognition, particularly when the target and masker were separated in space. Spatial release from masking (SRM) in the presence of a two-talker speech masker was expected to predict functional auditory performance as assessed by parent report. Method Participants were 5- to 14-year-olds with sensorineural or mixed UHL, age-matched children with normal hearing (NH), and adults with NH. Sound source localization was assessed on the horizontal plane (−90° to 90°), with noise that was either all-pass, low-pass, high-pass, or an unpredictable mixture. Speech recognition thresholds were measured in the sound field for sentences presented in two-talker speech or speech-shaped noise. Target speech was always presented from 0°; the masker was either colocated with the target or spatially separated at ±90°. Parents of children with UHL rated their children's functional auditory performance in everyday environments via questionnaire. Results Sound source localization was poorer for children with UHL than those with NH. Children with UHL also derived less SRM than those with NH, with increased masking for some conditions. Effects of UHL were larger in the two-talker than the noise masker, and SRM in two-talker speech increased with age for both groups of children. Children with UHL whose parents reported greater functional difficulties achieved less SRM when either masker was on the side of the better-hearing ear. Conclusions Children with UHL are clearly at a disadvantage compared with children with NH for both sound source localization and masked speech recognition with spatial separation. Parents' report of their children's real-world communication abilities suggests that spatial hearing plays an important role in outcomes for children with UHL.

Difficult Cases

Persons with a high frequency hearing loss are difficult cases for whom to find suitable amplification. We have experienced some success with this problem in our Hearing Clinics using a specially designed earmold with a hearing aid. Thirty-five cases with high frequency hearing losses were selected from our clinical files for analysis of test results using standard, vented, and open earpieces. A statistical analysis of test results revealed that PB scores in sound field, using an average conversational intensity level (70 dB SPL), were enhanced when utilizing any one of the three earmolds. This result was due undoubtedly to increased sensitivity provided by the hearing aid. Only the open earmold used with a CROS hearing aid resulted in a significant improvement in discrimination when compared with the group’s unaided PB score under earphones or when comparing inter-earmold scores. These findings suggest that the inclusion of the open earmold with a CROS aid in the audiologist’s armamentarium should increase his flexibility in selecting hearing aids for persons with a high frequency hearing loss.

AbstractObjective:Bone-anchored hearing aid surgery in younger children is a two-stage procedure, with a titanium fixture being allowed to osseointegrate for several months before an abutment is fitted through a skin graft. In the first procedure, it has been usual to place a reserve or sleeper fixture approximately 5 mm from the primary fixture as a backup in case the primary fixture fails to osseointegrate. This ipsilateral sleeper fixture is expensive, is often not used, and is placed in thinner calvarial bone where it is less likely to osseointegrate successfully. The authors have implanted the sleeper fixture on the contralateral side, with the additional objective of reducing the number of procedures for bilateral bone-anchored hearing aid implantation, providing a cost-effective use for the sleeper.Methods:The authors implanted the bone-anchored hearing aid sleeper fixture in the contralateral temporal bone instead of on the ipsilateral side in seven successive paediatric cases with bilateral conductive hearing loss requiring two-stage bone-anchored hearing aids, treated at the Royal Manchester Children's Hospital, UK.Results:The seven patients ranged in age from five to 15 years, with a mean age of 10 years; in addition, a 20-year-old with learning disability was also treated. In each case, the contralateral sleeper fixture was not needed as a backup fixture, but was used in four patients (57 per cent) as the basis for a second-side bone-anchored hearing aid.Conclusions:In children with bilateral conductive hearing loss, in whom a bilateral bone-anchored hearing aid is being considered and the second side is to be operated upon at a later date, we recommend placing the sleeper fixture on the contralateral side at the time of primary first-side surgery. Our technique provides a sleeper fixture located in an optimal position, where it also offers the option of use for a second-side bone-anchored hearing aid and reduces the number of procedures needed.

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.

Objetivo: Determinar, por meio de uma revisão sistemática, os resultados auditivos da reabilitação por meio de prótese auditiva em indivíduos com Perda Auditiva Unilateral (PAUn), no que se refere às habilidades de reconhecimento de fala na presença de ruído competitivo, localização da fonte sonora, satisfação e tempo de uso da prótese auditiva. Método: O levantamento bibliográfico foi realizado nas bases de dados Cochrane, Lilacs, Medline, Pubmed e Scielo, buscando triar estudos publicados entre 1997 e 2017, com os seguintes descritores em português: perda auditiva unilateral e auxiliares de audição; e em inglês: unilateral hearing loss e hearing aid. Os critérios de seleção dos estudos foram, amostra de indivíduos com PAUn, com idade mínima de 18 anos, que tivessem sido submetidos a avaliações de resultados voltados para a investigação do reconhecimento de fala na presença de ruído e/ou localização da fonte sonora e/ou satisfação e/ou tempo de uso da prótese auditiva, pré e pós-adaptação de prótese auditiva. Resultados: Após o levantamento bibliográfico, seis artigos foram analisados. Conclusão: Observou-se escassez de estudos voltados para a investigação da reabilitação por meio de prótese auditiva em indivíduos com PAUn. Apesar da maioria dos estudos demonstrarem benefício e satisfação com a adaptação de prótese auditiva, parte desta população não faz uso da mesma. A adaptação de prótese auditiva nesta população deve ser incentivada, levando em consideração a avaliação da demanda comunicativa de cada indivíduo, sua restrição de participação, principais queixas auditivas deste indivíduo pré e pós-adaptação e do ajuste de programação da prótese auditiva.

Objectives -to determine the normative data of sentence speech intelligibility in a free sound field and to estimate the applicability of the Russian Matrix Sentence test (RuMatrix) for assessment of the hearing aid fitting benefit. Material and methods. 10 people with normal hearing and 28 users of hearing aids with moderate to severe sensorineural hearing loss were involved in the study. RuMatrix test both in quiet and in noise was performed in a free sound field. All patients filled in the COSI questionnaire. Results. The hearing impaired patients were divided into two subgroups: the 1st with high and the 2nd with low hearing aid benefit, according to the COSI questionnaire. In the 1st subgroup, the threshold for the sentence intelligibility in quiet was 34.9 ± 6.4 dB SPL, and in noise -3.3 ± 1.4 dB SNR, in the 2nd subgroup 41.7 ± 11.5 dB SPL and 0.15 ± 3.45 dB SNR, respectively. The significant difference between the data of both subgroups and the norm was registered (p

Hearing Aid Use

Background: Unilateral sensorineural hearing loss (USNHL) can have a negative impact on functions associated with the advantages of balanced, binaural hearing. Although single-sided deafness, which is a complete loss of audibility in one ear, has gained increased interest in the published research, there is a gap in the literature concerning hearing aid outcomes for individuals with residual, or otherwise “aidable,” hearing in the affected ear. Purpose: To assess hearing aid outcomes for a group of individuals with USNHL with residual, aidable function. Research Design: A quasi-experimental study of hearing aid outcomes with paired comparisons made between unaided and aided test conditions. Study Sample: A convenience sample of twenty-two individuals with USNHL, with sufficient residual hearing in the affected ear as to receive audibility from use of a hearing aid, were recruited into the study from September 2011 to August 2012. Intervention: Each participant was fit with a digital behind-the-ear hearing aid coupled to a custom ear mold. Data Collection and Analysis: Assessments were performed at baseline (unaided) and after a three-month field trial (aided) with primary outcomes involving objective measures in sound field yielding signal-to-noise ratio loss (SNR Loss) via the Quick Speech-in-Noise Test and word recognition scores (WRS) via the Northwestern University Auditory Test, No. 6. Outcomes also involved the administration of two well-established subjective benefit questionnaires: The Abbreviated Profile of Hearing Aid Benefit (APHAB) and the 49-item Speech, Spatial, and Qualities of Hearing Scale (SSQ49). Results: As a group, participants showed significantly improved median SNR Loss thresholds when aided in a test condition that included spatial separation of speech and noise, with speech stimuli directed toward the worse ear and noise stimuli directed toward the better ear (diff. = −4.5; p < 0.001). Hearing aid use had a small, though statistically significant, negative impact on median SNR Loss thresholds, when speech and noise stimuli originated from the same 0° azimuth (diff. = 1.0; p = 0.018). This was also evidenced by the median WRS in sound field (diff. = −6.0; p = 0.006), which was lowered from 98% in the unaided state to 92% in the aided state. Results from the SSQ49 showed statistically significant improvement on all subsection means when participants were aided (p < 0.05), whereas results from the APHAB were generally found to be unremarkable between unaided and aided conditions as benefit was essentially equal to the 50th percentile of the normative data. At the close of the study, it was observed that only slightly more than half of all participants chose to continue use of a hearing aid after their participation. Conclusions: We observed that hearing aid use by individuals with USNHL can improve the SNR Loss associated with the interference of background noise, especially in situations when there is spatial separation of the stimuli and speech is directed toward the affected ear. In addition, hearing aid use by these individuals can provide subjective benefit, as evidenced by the APHAB and SSQ49 subjective benefit questionnaires.

AbstractSloping hearing loss imposes limits on audibility for high-frequency sounds in many hearing aid users. Signal processing algorithms that shift high-frequency sounds to lower frequencies have been introduced in hearing aids to address this challenge by improving audibility of high-frequency sounds.This study examined speech perception performance, listening effort, and subjective sound quality ratings with conventional hearing aid processing and a new frequency-lowering signal processing strategy called frequency composition (FC) in adults and children.Participants wore the study hearing aids in two signal processing conditions (conventional processing versus FC) at an initial laboratory visit and subsequently at home during two approximately six-week long trials, with the order of conditions counterbalanced across individuals in a double-blind paradigm.Children (N = 12, 7 females, mean age in years = 12.0, SD = 3.0) and adults (N = 12, 6 females, mean age in years = 56.2, SD = 17.6) with bilateral sensorineural hearing loss who were full-time hearing aid users.Individual performance with each type of processing was assessed using speech perception tasks, a measure of listening effort, and subjective sound quality surveys at an initial visit. At the conclusion of each subsequent at-home trial, participants were retested in the laboratory. Linear mixed effects analyses were completed for each outcome measure with signal processing condition, age group, visit (prehome versus posthome trial), and measures of aided audibility as predictors.Overall, there were few significant differences in speech perception, listening effort, or subjective sound quality between FC and conventional processing, effects of listener age, or longitudinal changes in performance. Listeners preferred FC to conventional processing on one of six subjective sound quality metrics. Better speech perception performance was consistently related to higher aided audibility.These results indicate that when high-frequency speech sounds are made audible with conventional processing, speech recognition ability and listening effort are similar between conventional processing and FC. Despite the lack of benefit to speech perception, some listeners still preferred FC, suggesting that qualitative measures should be considered when evaluating candidacy for this signal processing strategy.
