Hearing Assessment

<p class="abstract"><strong><span lang="EN-US">Background:</span></strong>Hearing loss is an invisible injury that has been viewed as an acceptable by-product of military service. It is imperative to detect hearing loss at early stage to take immediate remedial measures. In Indian armed forces the current method of assessment of hearing is primarily by Free Field Hearing which is obsolete and has numerous shortcomings. We contucted a study using free iOS application to detect hearing loss. The objectives of the study were to investigate the validity and reproducibility of app based hearing assement and free field hearing with clinical pure tone audiometer as gold standard. It is cross sectional intra-subject comparative study</p><p class="abstract"><strong><span lang="EN-US">Methods:</span></strong>The study was conducted at CHAF where 200 patients were accrued. Hearing assessment was carried out by Pure Tone Audiometry (PTA) which is gold standard. Thereafter these patients were subjected to hearing assessment by using windows application “freehearingtestsoftware.com” and by free field hearing (FFH).  </p><p class="abstract"><strong><span lang="EN-US">Results:</span></strong>Hearing assessment by FFH and hearing check app was compared with PTA. Hearing check app was found to be more sensitive than FFH (98% and 73%). Both modalities had high specificity (95% and 99%). The test retest reproducibility measured with Pearson correlation coefficient was high (0.99) with hearing check app.</p><p class="abstract"><strong><span lang="EN-US">Conclusions:</span></strong>Smart phone application like Hearing check app is a cheap and effective way to assess hearing with reasonable accuracy. It’s high sensitivity and high test retest reproducibility makes it an ideal tool for screening and early detection of hearing loss replacing out-dated free field hearing.</p><p class="abstract"><span lang="EN-US"> </span></p>

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.

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.

ABSTRACT Objective To assess central auditory function in Friedreich's ataxia. Methods A cross-sectional, retrospective study was carried out. Thirty patients underwent the anamnesis, otorhinolaryngology examination, pure tone audiometry, acoustic immittance measures and brainstem auditory evoked potential (BAEP) assessments. Results The observed alterations were: 43.3% in the pure tone audiometry, bilateral in 36.7%; 56.6% in the BAEP test, bilateral in 50%; and 46.6% in the acoustic immittance test. There was a significant difference (p < 0.05) in the comparison between the tests performed. Conclusion In the audiological screening, there was a prevalence of the descending audiometric configuration at the frequency of 4kHz, and absence of the acoustic reflex at the same frequency. In the BAEP test, there was a prevalence of an increase of the latencies in waves I, III and V, and in the intervals of interpeaks I-III, I-V and III-V. In 13.3% of the patients, wave V was absent, and all waves were absent in 3.3% of patients.

AbstractObjectivesSodium bromate is a strong oxidant, and bromate intoxication can cause irreversible severe-to-profound sensorineural hearing loss. This paper reports the first case in the English literature of bromate-induced hearing loss with hearing recovery measured by formal audiological assessment.Case reportA 72-year-old woman was admitted to hospital with complaints of profound hearing loss, nausea, diarrhoea and anuria after bromate ingestion in a suicide attempt. On admission, pure tone audiometry and auditory brainstem responses showed profound bilateral deafness. Under the diagnosis of bromate-induced acute renal failure and sensorineural hearing loss, continuous haemodiafiltration was performed. When dialysis was discontinued, pure tone audiometry and auditory brainstem responses showed partial threshold recovery from profound deafness.ConclusionSevere-to-profound sensorineural hearing loss is a common symptom of bromate intoxication. Bromate-induced hearing loss may be partially treated, and early application of continuous haemodiafiltration might be useful as a treatment for this intractable condition.
