    ABSTRACT: PURPOSE A priming stimulus activates and increases an association with the target stimulus. The goal of this research was to investigate whether current tinnitus measures are susceptible to increased error due to priming and, if so, examine the feasibility of using the Implicit Association Test for an alternative measurement of tinnitus-related distress. METHOD Participants completed two tinnitus-related questionnaires and an Implicit Association Test (IAT) online. RESULTS While participants with tinnitus did not view sound-related words as significantly more negative and IAT scores did not predict THI scores, priming did impact negative implicit attitudes toward sound-related words. CONCLUSIONS Based on these results it is suggested that current tinnitus measures may be susceptible to priming error and future studies should continue to pursue how the IAT can be utilized in the measure of tinnitus-related distress. Moreover, researchers should develop overt-behavioral measurements that can assess the validity of a tinnitus-IAT.

    ABSTRACT: PURPOSE The purpose of present study was to investigate associate of handedness with auditory middle latency responses (AMLRs) using topographic brain mapping by comparing amplitudes and latencies in frontocentral and hemispheric regions of interests (ROIs). METHOD 44 healthy normal hearing subjects (22 left-handed and 22 right-handed) were included in the study. AMLRs were recorded from 29 scalp electrodes in response to binaural 4 KHz tone bursts. RESULTS Frontocentral ROI comparisons revealed that Pa and Pb amplitudes were significantly larger in left-handed than right-handed group. Topographic brain maps showed different distributions in AMLR components between the two studied groups. In hemispheric comparisons, Pa amplitude differed significantly across groups. A left hemisphere emphasis of Pa was found in right-handed group but not in left-handed group. CONCLUSION Our study provides evidence that handedness associates with AMLR components in Frontocentral and hemispheric ROI. Handedness should be considered as an essential factor in clinical or experimental using of AMLRs.

    ABSTRACT: OBJECTIVES There is an opportunity to create a questionnaire focused on the primary activities impaired by tinnitus and therefore more sensitive to treatments. DESIGN We developed questions on; 1) emotions, 2) hearing, 3) sleep and 4) concentration. A 20-item questionnaire was administered to 158 patients. First, confirmatory factor analysis was used to select 3 questions per domain. Second, factor analysis was used to evaluate the appropriateness of the 12-item questionnaire. RESULTS The analysis indicated that the selected questions successfully represented four independent domains. Scores were correlated with the Tinnitus Handicap Questionnaire (r = 0.77, p < 0.01) and loudness (r = 0.40, p < 0.01). The sleep subscale correlated with the Pittsburgh Sleep Index (r = 0.68, p < 0.01); the emotion subscale correlated with the Beck Inventory (r = 0.66, p < 0.01) and the Trait Anxiety questionnaire (r = 0.67, p < 0.01). The average scores went from 51 to 38% following treatment. CONCLUSIONS The Tinnitus Primary Function Questionnaire is valid, reliable, and sensitive and can be used to determine in clinical trials.

    ABSTRACT: PURPOSE To evaluate the effects of policy changes on loss to follow-up rates and the ability to achieve the goals of the Joint Committee on Infant Hearing (JCIH, 2007) for diagnosis of hearing loss by three months, amplification within one month of diagnosis, and start of intervention by six months. METHODS Data were extracted from files of 111 infants including: date of birth, birth hospital, hometown, parents' ages, ethnicity, nursery status, medical history, age at initial evaluation and diagnosis, results of evaluation(s), age at hearing aid fitting and start of early intervention. Data were compared to previously published data from the clinic. RESULTS Policy changes led to a decrease in loss to follow-up and a younger age at diagnosis of hearing loss. Infants identified with hearing loss were fit with amplification at younger ages, but not within one month of diagnosis of hearing loss. Policy changes had positive outcomes on loss to follow-up and age of diagnosis and amplification. CONCLUSIONS Challenges remain in meeting the goals of amplification within one month of diagnosis and documenting the start of early intervention. Improved communication between and education of all parties involved in the care of infants is needed.

    ABSTRACT: PURPOSE The purpose of the study was to examine reception thresholds for sentences (RTSs) as a function of test session (N = 5) and noise (i.e., continuous and interrupted) in normal hearing adults. It was hypothesized that RTSs would be superior in interrupted noise and would be stable across repeated testing. METHOD Twenty-five normal hearing adults participated. RTSs were determined with Hearing in Noise Test sentences in continuous and interrupted noise presented at 65 dBA. An adaptive technique was used where sentences varied in intensity to converge on a level of 50% of correct performance. Sentence lists were counterbalanced with five unique lists in each continuous and interrupted noise. RESULTS RTS signal-to-noise ratios were significantly better in the interrupted noise (p < .0001). There was no effect of test session (p = .12) or a test session by noise interaction (p = .13). CONCLUSIONS Stable RTS signal-to-noise ratios across test sessions in both noises are consistent with the notion that a learning effect was not present in noise. Further, one may conclude that Hearing in Noise Test sentences provide stable measures of sentence recognition thresholds in normal hearing adults over time so long as sentences are unique/not repeated.

    ABSTRACT: PURPOSE Hearing loss prevention has always been an important issue for audiologists. The importance of hearing loss prevention education for young musicians is now recognized by the National Association for Music Education and the National Association of Schools of Music as well. Adopt-a-band is a commercial program designed to foster hearing loss prevention behavior in young musicians. METHODS This study assessed changes in ear plug use, measured using self-report on surveys, after Adopt-a-band training. Participants were members of two high school marching bands. Participants viewed an informational DVD, and reviewed fact sheets. Flat-attenuation earplugs were distributed and training provided. In addition, study participants engaged in discussion of hearing loss with an AuD student. RESULTS Prior to training, 23% of participants reported they had used hearing protection previously. Immediately after training, 94% of participants reported they planned to use hearing protection at least occasionally. In a final end-of-season survey season, earplug use was reliably increased; 62% of participants reported they used earplugs at least occasionally. CONCLUSIONS Earplug use was increased, but self-reported behavioral change was not as robust as predicted from self-reported participant intentions. Participant comments regarding factors that influenced their earplug use decisions suggest opportunities to improve training.

    ABSTRACT: PURPOSE The purpose of this study was to compare the benefits of three types of remote microphone hearing assistance technology (HAT), Adaptive Digital broadband, Adaptive Frequency Modulation (FM), and Fixed FM, through objective and subjective measures of speech recognition in clinical and real-world settings. METHODS Participants included 11 adults, ages 16 to 78 years, with primarily moderate-to-severe bilateral hearing impairment (HI) who wore binaural behind-the-ear hearing aids and 15 adults, ages 18 to 30 years, with normal hearing (NH). Sentence recognition in quiet and in noise and subjective ratings were obtained in three conditions of wireless signal processing. RESULTS Performance by the listeners with HI when using the Adaptive Digital technology was significantly better than that obtained with the FM technology, with the greatest benefits at the highest noise levels. The majority of listeners also preferred the digital technology when listening in a real-world noisy environment. The wireless technology allowed persons with HI to surpass persons with NH in speech recognition in noise with the greatest benefit occurring with Adaptive Digital technology. CONCLUSIONS The use of Adaptive Digital technology combined with speechreading cues would allow persons with HI to engage in communication in environments that would have otherwise not been possible with traditional wireless technology.

    ABSTRACT: PURPOSE The purpose of this research was to apply multiple perspectives as part of a systematic review to analyse literature regarding ethics in audiology. Audiologists are particularly vulnerable to the changing requirements of the discipline that compel them to straddle both professional obligations and business principles, creating a 'hybrid' professional. METHOD A two-phase mixed method approach was used to analyse publications. Publications were sorted into categories, namely ethics approach, author, decade, role of the audiologist, component of morality, and common themes. The sample consisted of peer-reviewed papers cited in MEDLINE, CINAHL, ERIC, MasterFILE Premier, E-Journals, Africa-Wide Information and Academic-Search Premier electronic database indexes, as well as non-peer-reviewed papers in the Seminars in Hearing journal. RESULTS The publications were predominantly philosophical, focused on the rehabilitative role of the audiologist, and addressed the moral judgement component of moral behaviour. CONCLUSIONS Despite the fact that knowledge of ethics grew between 1980 - 2010, this retrospective analysis identified gaps in current knowledge. Research is needed to address the unique ethical problems commonly encountered in all eight roles of the audiologist; patient perspectives on ethics; ethical approaches; factors affecting moral judgement, sensitivity, motivation and courage; as well as cultural dimensions of ethical practice in audiology.

    ABSTRACT: PURPOSE The purpose of this study was to develop a task to evaluate children's English and Spanish speech perception abilities in either noise or competing speech maskers. METHOD Eight bilingual Spanish-English and 8 age-matched monolingual English children (ages 4.9-16.4 years) were tested. A forced-choice, picture-pointing paradigm was selected for adaptively estimating masked speech reception thresholds. Speech stimuli were spoken by simultaneous bilingual Spanish-English talkers. The target stimuli were 30 disyllabic English and Spanish words, familiar to 5-year-olds and easily illustrated. Competing stimuli included either 2-talker English or 2-talker Spanish speech (corresponding to target language) and spectrally matched noise. RESULTS For both groups of children, regardless of test language, performance was significantly worse for the 2-talker than for the noise masker condition. No difference in performance was found between bilingual and monolingual children. Bilingual children performed significantly better in English than in Spanish in competing speech. For all listening conditions, performance improved with increasing age. CONCLUSIONS Results indicated that the stimuli and task were appropriate for speech recognition testing in both languages, providing a more conventional measure of speech-in-noise perception as well as a measure of complex listening. Further research is needed to determine performance for Spanish-dominant listeners and to evaluate the feasibility of implementation into routine clinical use.

    ABSTRACT: PURPOSE As more adult and child immigrants enter the United States each year, there is a high likelihood that the prevalence of childhood hearing loss in the United States is underestimated, given estimations of the number of immigrant children entering the country with hearing loss. METHOD Information was collected using online search engines and peer-reviewed journals. The most recent articles available through search engines included in EBSCOhost at the time were used. The gathered data were organized by emigrating country, and the 2 countries with the highest immigration rates were presented. Estimations of the number of children immigrating with hearing loss were made using data from published peer-reviewed articles and government reports on immigration. CONCLUSIONS The prevalence of hearing loss in the United States is underestimated when considering undetected hearing loss in immigrant children. The addition of the immigrant children from only Mexico and China presents a 7.5% increase in the total number of children in the United States with hearing loss. This reinforces the importance of early detection of hearing loss in these children, resulting in more accurate estimation of the rate of childhood hearing loss in the United States and better planning for intervention programs.

    ABSTRACT: PURPOSE Although a number of questionnaires are available to assess hearing aid benefit and general hearing disability, relatively few investigate spatial hearing ability in more complex listening situations. The aim of this study was to document the performance of normal hearing individuals using the Spatial Hearing Questionnaire (SHQ), and to compare performance with published data from cochlear implant users. METHOD Fifty-one participants with normal hearing participated. All participants completed the 24-item SHQ. Also, a factor analysis and reliability tests were performed. RESULTS Performance on the SHQ was high (87%) for the normal hearing participants. Subjective ratings varied across different listening situations: understanding speech in quiet (98%) was rated higher than sound localization (84%) and understanding speech in a background of noise (85%). Compared to previously published data (Tyler et al., 2009), normal hearing listeners rated their spatial hearing ability significantly better than bilateral and unilateral cochlear implant users. Results confirmed that the SHQ is a reliable measure of spatial hearing ability for normal hearing listeners. CONCLUSIONS Overall, results indicated that the SHQ is able to capture expected differences between normal hearing individuals and cochlear implant users. These new data can be used as targets following the provision of hearing devices.

    ABSTRACT: PURPOSE There are a number of craniosynostoses syndromes with hearing loss , including Muenke ,Apert , Pfeiffer, Crouzon, Beare-Stevenson, Crouzon with acanthosis nigricans, and Jackson-Weiss syndromes, that result from mutations in the FGFR genes. Studies of Fibroblast Growth Receptors (FGFRs) and their ligands, Fibroblast Growth Factors (FGFs) have revealed clues to the precise contribution of aberrant FGFR signaling to inner ear morphogenesis and the hearing loss encountered in craniosynostoses. The purpose of this article is to review basic studies of FGFRs with emphasis on their function and expression in the inner ear and surrounding structures. METHODS A Medline search was done to find basic science articles regarding FGFR, their ligands, their expression and relevant mouse models. Additional items searched included clinical descriptions and studies of individuals with FGFR related craniosynostosis syndromes. RESULTS The FGF signaling pathway is essential for the morphogensis and proper function of the inner ear ad auditory sensory epithelium. CONCLUSIONS The variable auditory phenotypes seen in individuals with Muenke syndrome may have a genetic basis, likely due to multiple interacting factors in the genetic environment or modifying factors. Further analysis and studies of mouse models of Muenke syndrome in particular, may provide clues as to the specific effects of the defining mutation in FGFR3 in the inner ear not only at birth but into adulthood. Particularly, investigations into these models may give insight into the variable expression and incomplete penetrance of this phenotype as well.

    ABSTRACT: OBJECTIVE To compare clinical features, predisposing factors and concomitant diseases between sporadic and familial Meniere's disease (MD). SUBJECTS A total of 250 definite MD patients fulfilling the AAO-HNS (1995) criteria, 149 sporadic and 101 familial. METHODS Retrospective chart review, postal questionnaire. RESULTS On average, familial patients were affected 5.6 years earlier than sporadic patients and they suffered from significantly longer spells of vertigo (p = 0.007). The prevalence of rheumatoid arthritis (p = 0.002) and other autoimmune diseases (p = 0.046) was higher among the familial patients, who also had more migraine (p = 0.036) and hearing impairment (HI) (p = 0.002) in their families. CONCLUSIONS The clinical features of familial and sporadic MD are very similar in general, but some differences do exist. Familial MD patients are affected earlier and suffer from longer spells of vertigo.

    ABSTRACT: PURPOSE To describe the inheritance patterns and auditory phenotype features of 3 Canadian families with mutations in two X-linked "deafness" genes (DFNX). METHOD Audiological, medical and family histories were collected and family members interviewed in order to compare hearing thresholds and case histories between cases with mutations in SMPX versus POU3F4. RESULTS The family pedigrees reveal characteristic X-linked inheritance patterns. Phenotypic features associated with the SMPX (DFNX4) mutation include early onset in males with rapid progression from mild and flat to sloping sensorineural loss, with highly variable onset and hearing loss severity in women. In contrast, phenotypic features associated with the POU3F4 (DFNX2) mutation are characterized by an early onset, mixed hearing loss, with fluctuation in males, and a normal hearing phenotype reported for females. CONCLUSIONS We show how this unique inheritance pattern, and both gender and mutation-specific phenotype variations can alert audiologists to the presence of X-linked genetic etiologies in their clinical practice. By incorporating this knowledge into clinical decision making, audiologists can facilitate the early identification of X-linked hearing loss, and contribute to the effective team management of affected families.

    ABSTRACT: PURPOSE To compare digit stimuli to popular spondees when measuring speech recognition threshold (SRT) in normal-hearing children, and to determine the influence of increment size using a descending method (ASHA, 1988). METHOD SRT was measured with paired digit stimuli (dSRT) and pediatric word stimuli (wSRT) using two step-sizes (5 dB, 2 dB) in 30 normal-hearing, typically-developing children aged 5;0 to 8;11 years. Pure-tone and SRT tests were administered in both ears. The dSRT and wSRT were compared to pure-tone average (PTA) thresholds per ear. RESULTS ANOVA revealed a significant interaction of Test and Step-size: PTA was significantly lower when measured with 2 dB than 5 dB increment; however, step-size yielded no differences in dSRT and wSRT. Right ear thresholds across tests were significantly lower than left ear. Pearson correlations were significant for all tests except two; dSRT was highly correlated to wSRT (r = .49-.72) in both ears. Regression analyses for both ears and step sizes revealed that prediction of the hearing threshold for speech from PTA was equally accurate for SRT measured with digit pairs or popular pediatric spondee stimuli. CONCLUSION Digit pairs are an appropriate alternative stimulus for SRT measurement in normal-hearing children. Future diagnostic audiology implications including application for other pediatric populations are discussed.

    ABSTRACT: PURPOSE The purpose of this review was to investigate the legislation about the provision of audiology services. Specifically, the goal of the review was to investigate the similarities and differences in legislation regarding the identification of and audiology services provided to children with hearing loss. METHOD A systematic review was conducted to collect state specific legislation regarding the audiology licensure requirements, requirements about the identification and management of children with hearing loss and insurance coverage regulations. Compiled data was analyzed for similarities and differences between state regulations and legislature. RESULTS All states require audiologists to hold licensure; however many differences exist between the requirements of acquiring and maintaining the license. Some states regulate the identification and management of children with hearing loss while others do not. Additionally, states differ in their regulation of services provided to children with hearing loss, who can provide these services, and what is covered by insurance. CONCLUSIONS It is critical for audiologists to understand the requirements of their state in the provision of audiology services. Specifically, it is important for audiologists to understand how the laws may impact the services they provide to children with hearing loss.

    ABSTRACT: To test whether training with amplified, clear speech, in regular room acoustics, will result in larger perceptual gains of auditory processing in elderly hearing-aids users. 36 elderly hearing impaired participants (ages: 64-88) were fitted with bilateral hearing-aids and were randomly assigned to 2 unequal groups. Study group participants were provided with seven sessions (one month) of individual listening training, during which a free conversation was conducted, aiming to stimulate the amplified ears with verbal auditory input. The control group participants were fitted with hearing-aids without training. Auditory processing changes were assessed using dichotic listening tasks. During hearing-aids use, dichotic listening scores, tested without the hearing-aids, improved in both groups, mainly in the non-dominant ears. The overall dichotic performance was significantly higher in the study group, and the main effect of auditory training was manifested on the dominant ear's scores. Hearing-aids use may improve auditory processing performance as tested in unaided conditions. Listening training has an additional beneficial effect on the dominant ear, i.e. the ear with the lesser potential for improvement. Listening training in elderly adults presumably enhanced acclimatization process by better recruiting the potential for auditory plasticity and improving attention recruitment.

    ABSTRACT: To determine the effects of sequential versus simultaneous bilateral hearing aids fitting on patient compliance. 36 hearing impaired older adultsparticipated in the study. Twelve participants were fitted with bilateral hearing aids simultaneously. The remaining participants were fitted sequentially: one hearing aid (to the left or to the right ear) was used initially; One month later, the other ear was also fitted with a hearing aid for bilateral use. Self-reports on usefulness and compliance were elicited after the first and second months of hearing aids use. In addition, the number of hours the hearing aids were used was extracted from the data loggings of each device. Simultaneous fitting resulted in high levels of compliance and consistent usage throughout the study period. Sequential fitting resulted in abrupt reduction in compliance and hours of use once the second hearing aid was added, both in the clinical scoring and in the data loggings. Simultaneous fitting of bilateral hearing aids results in better compliance compared to sequential fitting. The addition of a second hearing aid after a relatively short period of monaural use may lead to inconsistent use of both hearing aids.

    ABSTRACT: The authors report a seven-year-old male, designated FR, with severe sensorineural hearing loss. Features include round face, hypertelorism, epicanthal folds, and flat nasal root. Although there were early developmental concerns, all but his speech delay resolved when he was placed in an educational program that accommodated his hearing loss. To investigate genetic causes for his hearing loss, genetic studies were performed. History, physical examination, audiologic assessment, and imaging were performed according to usual practice. FMR1, GJB2, GJB6, and POU3F4 genes were sequenced. Chromosomal studies consisted of karyotyping and breakpoint analysis by fluorescence in situ hybridization (FISH). Results from FMR1, GJB2, GJB6, and POU3F4 sequencing and echocardiography, ECG, and abdominal ultrasound were normal. CT revealed a large fundus of the internal auditory canals and absence of the bony partition between the fundus and the adjacent cochlear turns with a widened modiolus bilaterally. CT findings are consistent with those described in persons with DFNX2 hereditary deafness. His karyotype was 46,inv(X)(q13q24),Y.ish inv(X)(XIST+)mat. FISH refined the breakpoints to inv(X)(q21.1q22.3). The Xq21.1 breakpoint was narrowed to a 25 kb region 450 kb centromeric to the DFNX2 gene, POU3F4. There are rare case reports of DFNX2 patients with chromosomal rearrangements positioned centromeric to POU3F4 and no mutations within the gene. We hypothesize that FR's hearing loss is caused by dysregulation of POU3F4 due to separation from regulatory elements affected by the inversion.
