Introduction: The Hum Test is used by some otolaryngologists as an alternative to the Weber Test to detect the presence and type of acute hearing change; however, its use has not yet been formally validated. Objective: To compare the diagnostic performance of Hum test with Weber test to detect hearing loss taking pure tone audiometry as the gold standard. Methodology: A prospective, cross-sectional study was conducted in the department of Otorhinolaryngology and Head and Neck surgery, Dhulikhel Hospital- Kathmandu University Hospital, from June 2018 to February 2019. Total of 257 patients were enrolled in the study and were subjected to 3 tests: Weber test, Hum test, and pure tone audiometry. Results: When examining patients with hearing loss, sensitivity of Hum test and weber test were 60.3% and 93.8 % respectively. In patients with CHL, sensitivity of Hum test was 55.7% while Weber test was 94.8%. In SNHL, it was 74.6% for Hum test and 90.5% for Weber test. Likewise, according to laterality of disease, sensitivity of Hum test was 58.6% for unilateral hearing loss and 65.2% for bilateral hearing loss. For Weber test it was 96.3% for unilateral and 86.4% for bilateral disease. Conclusion: Hum test is not as sensitive as Weber test in diagnosis of hearing loss both for conductive and sensorineural hearing loss.

Background Sudden sensorineural hearing loss (SSNHL) is an otologic emergency that warrants urgent management. Pure-tone audiometry remains the gold standard for definitively diagnosing SSNHL. However, in clinical settings such as primary care practices and urgent care facilities, conventional pure-tone audiometry is often unavailable. Objective This study aimed to determine the correlation between hearing outcomes measured by conventional pure-tone audiometry and those measured by the proposed smartphone-based Ear Scale app and determine the diagnostic validity of the hearing scale differences between the two ears as obtained by the Ear Scale app for SSNHL. Methods This cross-sectional study included a cohort of 88 participants with possible SSNHL who were referred to an otolaryngology clinic or emergency department at a tertiary medical center in Taipei, Taiwan, between January 2018 and June 2019. All participants underwent hearing assessments with conventional pure-tone audiometry and the proposed smartphone-based Ear Scale app consecutively. The gold standard for diagnosing SSNHL was defined as the pure-tone average (PTA) difference between the two ears being ≥30 dB HL. The hearing results measured by the Ear Scale app were presented as 20 stratified hearing scales. The hearing scale difference between the two ears was estimated to detect SSNHL. Results The study sample comprised 88 adults with a mean age of 46 years, and 50% (44/88) were females. PTA measured by conventional pure-tone audiometry was strongly correlated with the hearing scale assessed by the Ear Scale app, with a Pearson correlation coefficient of .88 (95% CI .82-.92). The sensitivity of the 5–hearing scale difference (25 dB HL difference) between the impaired ear and the contralateral ear in diagnosing SSNHL was 95.5% (95% CI 87.5%-99.1%), with a specificity of 66.7% (95% CI 43.0%-85.4%). Conclusions Our findings suggest that the proposed smartphone-based Ear Scale app can be useful in the evaluation of SSNHL in clinical settings where conventional pure-tone audiometry is not available.

AbstractBackgroundPaediatric hearing loss rates in Ghana are currently unknown.MethodsA cross-sectional study was conducted in peri-urban Kumasi, Ghana; children (aged 3–15 years) were recruited from randomly selected households. Selected children underwent otoscopic examination prior to in-community pure tone screening using the portable ShoeBox audiometer. The LittlEars auditory questionnaire was also administered to caregivers and parents.ResultsData were collected from 387 children. After conditioning, 362 children were screened using monaural pure tones presented at 25 dB. Twenty-five children could not be conditioned to behavioural audiometric screening. Eight children were referred based on audiometric screening results. Of those, four were identified as having hearing loss. Four children scored less than the maximum mark of 35 on the LittleEars questionnaire. Of those, three had hearing loss as identified through pure tone screening. The predominant physical finding on otoscopy was ear canal cerumen impaction.ConclusionPaediatric hearing loss is prevalent in Ghana, and should be treated as a public health problem warranting further evaluation and epidemiology characterisation.

Purpose The aim of this study was to assess the proportion of patients seen in a tinnitus and hyperacusis therapy clinic for whom presentation levels based on the British Society of Audiology (BSA)–recommended procedures for pure-tone audiometry and determination of uncomfortable loudness levels (ULLs) exceed ULLs, leading to discomfort during administration of these procedures. Method This was a retrospective cross-sectional study of 362 consecutive patients who attended a National Health Service audiology clinic for tinnitus and/or hyperacusis rehabilitation. Results For 21% of the patients, presentation levels based on the BSA procedure for pure-tone audiometry exceeded the ULL for at least 1 of the measured frequencies (excluding the first frequency tested, 1 kHz): 0.25, 0.5, 2, 3, 4, 6, and 8 kHz. For 24% of patients, the starting presentation level of 60 dB hearing level recommended for determination of ULLs exceeded the ULL for at least 1 frequency. Conclusion The starting presentation levels used for pure-tone audiometry and measurement of ULLs should be lower than those recommended by the BSA for people with tinnitus and hyperacusis.

Background: Sound protector is an essential tool to protect hearing.Objective: The purpose of the present study was to see the hearing status of traffic police with or without sound protector.Methodology: The cross-sectional study was conducted in the Department of Otolaryngology and Head Neck Surgery at Bangabandhu Sheikh Mujib Medical University, Dhaka from January 2003 to June 2004 for a period of one and half year. Traffic police who were working in the Dhaka metropolitan city at any age were included as study population. Hearing status was measured to all subjects. The traffic police at any age working in the Dhaka metropolitan city with the duration of service more than 5 years were included as study population. Otoscopic examination, tuning fork test and pure tone audiometry were performed by clinical audiometer (AC 33) with two channels, with TDH39 earphones among the entire study subject.Result: A total number of 100 traffic polices working in Dhaka metropolitan city were examined. Highest (56%) number of the respondents was in between 30 to 40 years of age group. The mean age with SD was 36.15 ±5.5. In this study 53.0% respondents found to have exposure of 6 to 10 years and 16.0% found to have exposure between 16 to 20 years. It was found that 26 traffic police used ear protector occasionally. Among them 7(26.9%) subjects had different degree of hearing loss. Nonusers had higher rate (23%) of hearing loss (p=0.685).Conclusion: In conclusion use of sound protector by traffic police is not significantly related with the hearing loss though this is clinically significant.Journal of Current and Advance Medical Research 2017;4(1):13-16

<p class="abstract"><strong>Background:</strong> Tympanic membrane perforations are common cause of hearing loss. There are very few systematic studies that have evaluated the size and location of a perforation to the degree of hearing loss, this study correlates the size and location of tympanic membrane perforation to the pattern of hearing loss.</p><p class="abstract"><strong>Methods:</strong> The study design was based on cross sectional study. Ninety-six ears of dry tympanic membrane perforation of CSOM mucosal type were selected. Photographs of the tympanic membrane perforations were taken and size measured using the “Image J” software. The area of perforation was compared to hearing loss measured by pure tone audiometry.  </p><p class="abstract"><strong>Results:</strong> Ninety-six patients, aged 15-60 years with perforated eardrums were studied. Size of tympanic membrane perforation showed moderate level of correlation with hearing loss (Pearson r value=0.463). The various locations of perforations were: posterior (23 ears with Mean hearing loss 28.6±7.7 dB), anterior (31 ears with Mean hearing loss 26.5±7.8dB), subtotal (42 ears with Mean hearing loss 34.2±8.2 dB).</p><p class="abstract"><strong>Conclusions:</strong> The hearing loss is frequency dependent, with maximum hearing loss at lower frequencies. Irrespective of size of perforation the hearing loss was the least for frequency of 2000Hz. Magnitude of hearing loss increases with increase in size of tympanic membrane perforation. Perforation posterior to handle of malleus resulted in more hearing loss than perforations involving anterior to the handle of malleus.</p>

Objective: To calculate the accuracy, sensitivity, specificity and positive predictive values of the Siemens HearCheck™ Navigator in detecting hearing loss and to compare values of these parameters when the examination is done in a soundproof booth and in a quiet room.   Methods: Design: Analytical, cross-sectional study Setting: Tertiary Public University Hospital Patients: Patients seen at the Ear Unit of a tertiary public university hospital from June 2009 to August 2010 were tested using the Siemens HearCheck™ Navigator and pure tone audiometry, inside a soundproof audiometry booth and in a quiet room with an ambient noise of 50dB, with a different investigator for each examination. Each ear was treated as a separate subject. Results obtained from the HearCheck™ Navigator were designated as observed values and were classified as “no hearing loss” for green light, and “with hearing loss” for yellow or red lights. Results were compared with pure tone air conduction averages designated as gold standard values. Normal hearing acuity (0-25 dB) was classified as no hearing loss. Pure tone air conduction averages of 26dB and above were classified as “with hearing loss” and were further stratified as mild hearing loss (26-40dB) and moderate or worse hearing loss (>41 dB). Observed and gold standard values were compared and tabulated in a 2x2 table for all levels of hearing loss, mild hearing loss, and moderate or worse hearing loss. Accuracy, sensitivity, specificity, positive and negative predictive values of the Siemens HearCheck™ Navigator inside a soundproof audiometry booth and in a quiet room were determined using pure tone audiometry as the gold standard.   Results: 100 patients (200 ears) were tested, with a median age of 43 years old (range 15-75), and an almost equal number of male and female participants (52 males, 48 females). Accuracy rate of the Siemens HearCheck™ Navigator inside the soundproof audiometry booth and in a quiet room were 82.5% and 84% respectively for all levels of hearing loss. Sensitivity, specificity, positive and negative predictive values were similar whether the examination was done inside the soundproof audiometry booth or in a quiet room. These values were notably higher in patients with moderate or worse hearing loss compared to patients with mild hearing loss.   Conclusion: The Siemens HearCheck™ Navigator shows potential as an accurate, portable, easy-to-use tool to screen for hearing loss, especially for cases of moderate or worse hearing loss, without the need for soundproof audiometry booths or special training. It is recommended that further studies be done to differentiate degrees of hearing loss, and to evaluate its usefulness in other target populations, including school children and the elderly.   Keywords: hearing screening, hearing screening tool, accuracy, hearingloss, HearCheck™ Navigator

Pure Tone Audiogram

Objective: To assess audiometry investigations in patients having complaint of tinnitus, vertigo or hearing impairment after recovery from COVID-19 disease, having no external or middle ear diseases. Study Design: Cross-sectional study. Place and Duration of Study: United Medical and Dental College, Creek General hospital, Korangi, Karachi Pakistan, from March to May 2021. Methodology: A total of 60 patients were included in this study who had recovered from the primary COVID-19 infection and reported with the complaints of tinnitus, vertigo and hearing loss. Pure tone audiogram was assessed for sensorineural deafness, its severity and frequencies affected. Pearson Chi square test was used to see the relation of symptoms with severity of hearing loss. Results: There were 42 (70%) males and 18 (30%) female patients with age range from 18-50 years with mean age of 28.4 ± 8.1 years. Tinnitus was the most common complaint (83.3%) followed by hearing loss (28.3%) and vertigo (23.3%) patients. None of the patients with complaint of hearing loss had normal pure tone audiogram in either right or left ear (p=0.000). Patients with all the three complaints had more hearing impairment where majority had moderate or severe hearing loss (p=0.000). All patients with isolated complaint of vertigo (9 patients) had normal audiogram in both ears (p=0.000). Conclusion: Auditory and vestibular system involvement in reasonably common in COVID-19 patients. Tinnitus is the most frequent symptom and it should be investigated with full audiological investigations.
