Abstract Purpose In most cases, tinnitus co-exists with hearing loss, suggesting that poorer speech understanding is simply due to a lack of acoustic information reaching the central nervous system (CNS). However, it also happens that patients with tinnitus who have normal hearing also report problems with speech understanding, and it is possible to suppose that tinnitus is to blame for difficulties in perceptual processing of auditory information. The purpose of the study was to evaluate the auditory processing abilities of normally hearing subjects with and without tinnitus. Methods The study group comprised 97 adults, 54 of whom had normal hearing and chronic tinnitus (the study group) and 43 who had normal hearing and no tinnitus (the control group). The audiological assessment comprised pure-tone audiometry and high-frequency pure-tone audiometry, impedance audiometry, and distortion product oto-acoustic emission assessment. To evaluate possible auditory processing deficits, the Frequency Pattern Test (FPT), Duration Pattern Test (DPT), Dichotic Listening Test (DLT), and Gap Detection Threshold (GDT) tests were performed. Results The tinnitus subjects had significantly lower scores than the controls in the gap detection test (p < 0.01) and in the dichotic listening test (p < 0.001), but only for the right ear. The results for both groups were similar in the temporal ordering tests (FPT and DPT). Right-ear advantage (REA) was found for the controls, but not for the tinnitus subjects. Conclusion In normally hearing patients, the presence of tinnitus may be accompanied with auditory processing difficulties.

Visual-to-auditory sensory substitution devices (SSDs) provides improved access to the visual environment for the visually impaired by converting images into auditory information. Research is lacking on the mechanisms involved in processing data that is perceived through one sensory modality, but directly associated with a source in a different sensory modality. SSDs may be similar to reading, as an image (printed word) is converted into sound (when read aloud). Reading, and language more generally, are typically lateralised to the left cerebral hemisphere. Yet, unlike symbolic written language, SSDs convert images to sound based on visuospatial properties, with the right cerebral hemisphere potentially having a role in processing such visuospatial data. Here we investigated whether there is a hemispheric bias in the processing of visual-to-auditory sensory substitution information and whether that varies as a function of expertise and visual ability. We assessed the lateralisation of auditory processing with two tests: a standard dichotic listening test and a novel dichotic listening test created using the auditory information produced by an SSD, The vOICe. Although standard dichotic listening is lateralised to the left hemisphere, the auditory processing of images in SSDs is bilateral, possibly due to the increased influence of right hemisphere processing.

Purpose The effects of neurological diseases on the auditory system have been a notable issue for investigators because the auditory pathway is closely associated with neural systems. The purposes of this study are to evaluate the efferent auditory system function and hearing quality in Parkinson's disease (PD) and to compare the findings with age-matched individuals without PD to present a perspective on aging. Method The study included 35 individuals with PD (mean age of 48.50 ± 8.00 years) and 35 normal-hearing peers (mean age of 49 ± 10 years). The following tests were administered for all participants: the first section of the Speech, Spatial and Qualities of Hearing Scale; pure-tone audiometry, speech audiometry, tympanometry, and acoustic reflexes; and distortion product otoacoustic emissions (DPOAEs) and contralateral suppression of DPOAEs. SPSS Version 25 was used for statistical analyses, and values of p < .05 were considered statistically significant. Results There were no statistically significant differences in the pure-tone audiometry thresholds and DPOAE responses between the individuals with PD and their normal-hearing peers ( p = .732). However, statistically significant differences were found between the groups in suppression levels of DPOAEs and hearing quality ( p < .05). In addition, a statistically significant and positive correlation was found between the amount of suppression at some frequencies and the Speech, Spatial and Qualities of Hearing Scale scores. Conclusions This study indicates that medial olivocochlear efferent system function and the hearing quality of individuals with PD were affected adversely due to the results of PD pathophysiology on the hearing system. For optimal intervention and follow-up, tasks related to hearing quality in daily life can also be added to therapies for PD.

Previously reward-associated stimuli have consistently been shown to involuntarily capture attention in the visual domain. Although previously reward-associated but currently task-irrelevant sounds have also been shown to interfere with visual processing, it remains unclear whether such stimuli can interfere with the processing of task-relevant auditory information. To address this question, we modified a dichotic listening task to measure interference from task-irrelevant but previously reward-associated sounds. In a training phase, participants were simultaneously presented with a spoken letter and number in different auditory streams and learned to associate the correct identification of each of three letters with high, low, and no monetary reward, respectively. In a subsequent test phase, participants were again presented with the same auditory stimuli but were instead instructed to report the number while ignoring spoken letters. In both the training and test phases, response time measures demonstrated that attention was biased in favour of the auditory stimulus associated with high value. Our findings demonstrate that attention can be biased towards learned reward cues in the auditory domain, interfering with goal-directed auditory processing.

Целью исследования был сравнительный анализ жалоб и аудиологических показателей у пациентов сурдологического центра в зависимости от возраста. Представлены результаты обследования 300 первичных пациентов (случайная выборка), обратившихся к сурдологу-оториноларингологу в течение 1 мес. В группу молодых пациентов (19-44 года) вошли 40 человек; в группу среднего возраста (45- 59 лет) - 62 человека; в группу пожилых (60-74 года) - 100 человек; в группу старческого возраста (75-90 лет) - 98 человек. Обследование включало сбор жалоб и анамнеза, ЛОР-осмотр, тональную пороговую аудиометрию, импедансометрию, речевую аудиометрию в наушниках для выявления признаков центральных слуховых расстройств или в свободном звуковом поле для оценки эффективности слухопротезирования. Установлено, что для ранней диагностики тугоухости и профилактики возрастных сенсорнокогнитивных дисфункций целесообразно использовать не только результаты тональной пороговой аудиометрии, но и данные речевой аудиометрии, а также анализ субъективных жалоб. Результаты работы свидетельствуют о необходимости организации скрининга состояния слуха в рамках диспансеризации населения старше 60 лет. The aim of the study was a comparative analysis of complaints and audiological findings in patients of the audiological center depending on their age. The results of the examination of 300 fi rstly consulted patients (random sample) are presented. The group of young patients (19-44 years) included 40 people; middle age (45-59 years) - 62 people; elderly (60-74 years) - 100 people; senile age (75-90 years) - 98 people. The survey included the collection of complaints and anamnesis, ENT checkup, pure tone audiometry, impedancemetry, speech audiometry in headphones to detect the signs of Central Auditory Processing Disorder or in the free sound field to assess the effectiveness of hearing aids. It was found that for early diagnosis of hearing loss and prevention of age-related sensory-cognitive dysfunction, it is advisable to use not only the results of pure tone audiometry, but also the data of speech audiometry, as well as the analysis of subjective complaints. The results of the work indicate the need for hearing screening in the population over 60 years old.

Background: Patients with hearing disturbance will generally undergo pure tone audiometry andspeech audiometry in a quiet room, but those examinations cannot evaluate the ability to understand speech in daily environment with a noisy background. Words in noise test will provide valuable informationregarding patient’s hearing problem in noise. Purpose: To evaluate the hearing threshold using wordsin noise test in adults with normal hearing. Method: This cross-sectional study was conducted in CiptoMangunkusumo Hospital from January to April 2017. All subjects who fulfilled the inclusion and exclusioncriteria underwent pure tone audiometry, speech audiometry, and words in noise test. Results: A total of71 individuals with normal hearing were recruited for this study. Words in noise test showed the medianvalue of 67 dB and 100 dB for Speech Recognition Threshold (SRT) 50% and Speech DiscriminationScore (SDS) 100%, respectively. The SRT 50% and SDS 100% were significantly higher in the age group40–60 years compared to the age group 18–39 years. There was also a statistically significant differencebetween males and females at SRT 50% assessed by words in noise audiometry. Conclusion: Wordsin noise test showed a statistically significant difference in SRT 50% and SDS 100% between two agegroups, but no difference was found between genders. The result of this study can be used as a referencefor SRT and SDS values of speech audiometry test in noise.Keywords: words in noise, speech audiometry, speech recognition threshold, speech discrimination score ABSTRAKLatar belakang: Pasien dengan gangguan pendengaran umumnya menjalani pemeriksaanaudiometri nada murni dan audiometri tutur di ruangan yang sunyi, tetapi pemeriksaan ini tidakdapat menggambarkan kemampuan pemahaman wicara di lingkungan sehari-hari yang ramai.

Abstract Age-related hearing loss (HL), defined by a pure-tone average (PTA) &gt;25 decibels (dB) has been associated with depressive symptoms. We aimed to assess whether this association is present when hearing is better than the arbitrary, but widely-used, 25 dB threshold. The sampled population was the multicentered Hispanic Community Health Study (n=5,165). Cross-sectional data from 2008-2011 were available. Hearing was measured with pure tone audiometry. Clinically-significant depressive symptoms (CSDS) were defined by a score ≥10 on the 10-item Center for Epidemiologic Studies Depression Scale (CESD-10). Participants’ mean age was 58.3 years (SD=6.2, range=50-76). Among those with classically-defined normal hearing (PTA ≤25 dB), a 10 dB increase in HL was associated with 1.26 times the odds (95% CI=1.11, 1.42) of CSDS, adjusting for age, gender, education, vascular disease, and hearing aid use (p25 dB; p&lt;0.001). Results held even for a stricter HL cutpoint of 15 dB. Among subjects with strictly normal hearing (PTA ≤15 dB), a 10 dB increase in HL was associated with 1.47 (1.14, 1.90) times the odds of CSDS, adjusting for confounders (p&lt;0.01). Results also held when defining CSDS by an alternative CESD-10 score ≥16. In conclusion, increasing hearing thresholds were independently associated with CSDS among adults with subclinical HL (PTA ≤25 dB). Studies investigating whether treating HL can prevent late life depression should consider a lower threshold for defining HL.

Dichotic listening (DL) procedures are commonly employed in the evaluation of auditory processing in children. Review of the various clinical tests reveals considerable diversity in both the signals employed and their mode of administration. The extent to which other non auditory-specific factors influence the test outcome is often difficult to determine. Individual differences in memory, attention, facility with test stimuli, and report strategy are always of potential concern in the interpretation of results.In the present study, we examined behavioral and electrophysiological (ERP) responses for 20 children during two DL tasks. Two groups of children were evaluated. One group was comprised of children who showed substantial ear differences on clinical measures of DL; the other group showed no such deficits and served as age-matched controls. In one of the DL tasks, participants monitored dichotic stimuli using the divided-attention (unfocused) mode. In the other DL task, a directed-attention (focused) mode was employed. Both tasks involved simple "same-different" judgments for real words presented in a basic reference-probe paradigm. We purposefully sought an easy DL task in order to minimize the number of extra-auditory factors influencing their performance. For control purposes, a diotic procedure involving the same stimuli was also included.Results showed that the amplitude of the elicited late-positive component (LPC) was smaller and prolonged in latency for the group of poor listeners as compared to the control group. This finding occurred only when dichotic stimuli were presented in the divided-attention mode. When participants directed their attention to a single side, or when listening in a diotic mode, the LPC for both groups was more similar. Group differences in the N400 component were apparent for both listening tasks. Results are discussed in relation to an inability of some children to inhibit processing of unattended auditory information. Implications for the clinical administration of dichotic listening tests are also discussed. Los procedimientos de Audición Dicótica (DL) son comúnmente empleados en la evaluación del procesamiento auditivo en niños. La revisión de varias pruebas clínicas revela una diversidad considerable tanto en las señales empleadas como en su modo de administración. En qué grado otros factores no específicos de la audición influyen en los resultados de las pruebas es a menudo difícil de determinar. Las diferencias individuales en memoria, atención, facilidad con los estímulos de la prueba y la estrategia de reporte, tienen siempre influencia potencial en la interpretación de los resultados. En el presente estudio, examinamos respuestas conductuales y electrofisiológicas (ERP) en 20 niños con dos tareas de DL. Se evaluaron dos grupos de niños. Un grupo estaba constituido por niños que mostraban diferencias sustanciales entre los oídos en las mediciones clínicas de la DL; el otro grupo no mostró tal déficit y sirvieron como controles pareados por edad. En una de las tareas de DL, los participantes monitorearon estímulos dicóticos utilizando el modo de atención dividida (no concentrada). En la otra tarea de DL, se empleó un modo de atención dirigida (concentrada). Ambas tareas involucraron juicios simples de "igual-diferente" para palabras reales presentadas en un paradigma de sondeo de diferencia básica. A propósito, buscamos una tarea de DL fácil, para minimizar el número de factores extra-auditivos que influían en el desempeño. Para propósitos de control, se incluyó también un procedimiento diótico que utilizara los mismos estímulos. Los resultados muestran que la amplitud del componente positivo tardío (LPC) generado era más pequeña y más prolongada en latencia para el grupo de oyentes pobres comparado con el grupo control. Este hallazgo tuvo lugar sólo cuando se presentaron estímulos dicóticos en el modo de atención dividida. Cuando los participantes dirigieron su atención a un sólo lado, o cuando escucharon en un modo diótico, el LPC para ambos grupos fue similar. Las diferencias de grupo en el componente N400 fueron aparentes para ambas tareas de audición. Se discuten los resultados en relación con la incapacidad de algunos niños de inhibir el procesamiento de información auditiva a la que no se le está prestando atención. Se discuten las implicaciones para la administración clínicas de pruebas de audición dicótica.

AbstractWe wondered how many women had experienced a sensation of fullness in the ear during pregnancy. To address this question, data were obtained from a group of healthy women who attended the gynaecology clinic in our hospital as pregnancy cases between February 1995 and January 1998 and who volunteered to participate in our study. A control group was drawn from healthy female co-medical staff members of our hospital who had never been pregnant. The data used for comparing the two groups were taken from a questionnaire about ear problems that was presented to all subjects. The results suggest that ear problems may be increased in pregnancy, particularly for hypotensive pregnant women. However, even for pregnant women complaining of ear problems, pure-tone audiometry and impedance audiometry showed normal hearing in all cases. Furthermore, these women's complaints resolved completely on delivery of their babies.

Background: According to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, diagnosis of speech sound disorder (SSD) requires a determination that it is not the result of other congenital or acquired conditions, including hearing loss or neurological conditions that may present with similar symptomatology. Purpose: To examine peripheral and central auditory function for the purpose of determining whether a peripheral or central auditory disorder was an underlying factor or contributed to the child’s SSD. Research Design: Central auditory processing disorder clinic pediatric case reports. Study Sample: Three clinical cases are reviewed of children with diagnosed SSD who were referred for audiological evaluation by their speech–language pathologists as a result of slower than expected progress in therapy. Results: Audiological testing revealed auditory deficits involving peripheral auditory function or the central auditory nervous system. These cases demonstrate the importance of increasing awareness among professionals of the need to fully evaluate the auditory system to identify auditory deficits that could contribute to a patient’s speech sound (phonological) disorder. Conclusions: Audiological assessment in cases of suspected SSD should not be limited to pure-tone audiometry given its limitations in revealing the full range of peripheral and central auditory deficits, deficits which can compromise treatment of SSD.
