    Recreational noise exposure has become a major threat to the hearing system, and this
    includes exposure to loud noise during group exercises such as Zumba Fitness, where loud music plays an
    important role. This study aimed to assess the noise exposure and hearing threshold profile among Zumba
    Fitness regulars in Kuantan, Malaysia. MATERIALS AND METHODS: Noise exposure and hearing profile
    threshold were measured during Zumba Fitness sessions at a fitness studio in Kuantan, Malaysia from 24th
    June 2014 to 12th August 2014. Noise exposure was measured using a noise dosimeter for one hour of Zumba
    Fitness session with a total of nine sessions run by three different instructors while sound level pressure was
    taken using a sound level meter during ambient, peak session and during cooling down. Thirty participants
    answered questionnaires and underwent pure tone diagnostic audiometry test at a local clinic for hearing
    threshold documentation. RESULTS: Some areas of the hall posed higher risks of causing noise-induced
    hearing loss especially near the amplifiers. There were periods when the hearing level exceeded 115 dBA.
    Early abnormal pattern could be observed in the hearing profiles of some of the participants to suggest
    preliminary hearing problems. CONCLUSION: Zumba Fitness regulars have a risk of developing noise-induced
    hearing loss and preventive steps should be properly addressed as NIHL is permanent and irreversible.

    This paper aims to synthesize available literature on occupational noise in Malaysia and to relate this to the current noise management practices and control. The review focuses on several main
    scopes; i) history of occupational noise management in Malaysia; ii) legislative developments and legal precedents of occupational noise in Malaysia ; and iii) the hearing conservation programs (HCP) and hearing loss prevention programs (HLPP). Narrative review and synthesis. Related publications and references were identified through several ways: i) by structured searches in PubMed, Google scholar, Web of Knowledge and Science Direct using the combinations of ‘occupational noise’, ‘noise induced hearing loss; ‘hearing’, ‘knowledge’, awareness’, ‘hearing conservation program’, ‘hearing protection devices’ as key words ii) by inspecting the reference lists of relevant articles. The number of publications within the audiology which address this topic, is rather limited. All the above mentioned scopes were discussed and synthesis of literature from other related fields such as medical, health and occupational safety and health were also referred to facilitate the discussion. This paper concludes that there are an emerging trend for the studies of occupational noise Malaysia in the literature. However, the effectiveness of HCP in Malaysia, and to what extent it is accepted and being implemented is yet to be investigated.

    Objective: This study aims to investigate the auditory sensory gating capacity in Huffaz using an auditory brainstem response (ABR) test with and without psychological tasks.

    Methods: Twenty-three participants were recruited for this study. The participants were comprised of 11 Huffaz who memorized 30 chapters of the Islamic Scripture (from the Quran) and 12 non-Huffaz as the control group. All participants had normal hearing perception and underwent an ABR test with and without psychological tasks. The ABR was elicited at 70 dB nHL using a 3000 Hz tone burst stimulus with a 2-0-2 cycle at a stimulus repetition rate of 40 Hz. The ABR wave V amplitude and latencies were measured and statistically compared. A forward digit span test was also conducted to determine participants' working memory capacity.

    Results: There were no significant differences in the ABR wave V amplitudes and latencies between Huffaz and non-Huffaz in ABR with and without psychological tasks. There were also no significant differences in the ABR wave V amplitudes and latencies in both groups of ABR with and without psychological tasks. In addition, no significant differences were identified in the digit span working memory score between both groups.

    Conclusions: In this study, based on the ABR findings, Huffaz showed the same auditory sensory gating capacity as the non-Huffaz group. The ABR result was consistent with the digit span working memory test score. This finding implies that both groups have similar working memory performance. However, the conclusion is limited to the specific assessment method that we used in this study.

    Sudden sensorineural hearing loss (SSNHL) is an otology emergency and carries significant morbidity if the diagnosis is missed. It can present to any specialty but in our local setting the patient usually presents to primary care as it is easily accessible. We present a case of SSNHL that was initially presented to a primary care centre and the patient was reassured without any investigation being carried out. SSNHL has many causes thus making diagnosis difficult. However, with knowledge of its possible, a diagnosis can be made and appropriate management can be advocated to the patient. Hence, we discuss the three main causes of SSNHL, while emphasizing the immune system-mediated mechanism as the main cause in this case.

    BACKGROUND AND OBJECTIVES: There is growing interest in the use of the Level-specific (LS) CE-Chirp® stimulus in auditory brainstem response (ABR) due to its ability to produce prominent ABR waves with robust amplitudes. There are no known studies that investigate the test-retest reliability of the ABR to the LS CE-Chirp® stimulus. The present study aims to investigate the test-retest reliability of the ABR to the LS CE-Chirp® stimulus and compare its reliability with the ABR to standard click stimulus at multiple intensity levels in normal-hearing adults.

    SUBJECTS AND METHODS: Eleven normal-hearing adults participated. The ABR test was repeated twice in the same clinical session and conducted again in another session. The ABR was acquired using both the click and LS CE-Chirp® stimuli at 4 presentation levels (80, 60, 40, and 20 dBnHL). Only the right ear was tested using the ipsilateral electrode montage. The reliability of the ABR findings (amplitudes and latencies) to the click and LS CE-Chirp® stimuli within the same clinical session and between the two clinical sessions was calculated using an intra-class correlation coefficient analysis (ICC).

    RESULTS: The results showed a significant correlation of the ABR findings (amplitude and latencies) to both stimuli within the same session and between the clinical sessions. The ICC values ranged from moderate to excellent.

    CONCLUSIONS: The ABR results from both the LS CE-Chirp® and click stimuli were consistent and reliable over the two clinical sessions suggesting that both stimuli can be used for neurological diagnoses with the same reliability.

    While previous research has shown that during mental imagery participants look back to areas visited during encoding it is unclear what happens when information presented during encoding is incongruent. To investigate this research question, we presented 30 participants with incongruent audio-visual associations (e.g. the image of a car paired with the sound of a cat) and later asked them to create a congruent mental representation based on the auditory cue (e.g. to create a mental representation of a cat while hearing the sound of a cat). The results revealed that participants spent more time in the areas where they previously saw the object and that incongruent audio-visual information during encoding did not appear to interfere with the generation and maintenance of mental images. This finding suggests that eye movements can be flexibly employed during mental imagery depending on the demands of the task.

    Working for a minimum of 8 hours, 6 days a week might have exposed the workers of public transportation to
    high noise risks. However, occupational exposures in their workplace have not been adequately characterized and
    identified. Assessment of occupational noise exposure among workers at five public transportation stations was made
    using Sound Level Meter and through questionnaire survey. The data obtained was combined to estimate the work
    shift exposure level and health impacts to the workers by using statistical analysis. The respondents participated in the
    survey to identify the symptoms of noise-induced hearing loss and other health-related problems. Results of the study
    indicated that occupational noise exposure among workers for Mean Continuous Equivalent Level, Leq= 76.17 dB(A)
    presents small risks of developing a hearing disability. Some of the workers show symptoms of noise-induced hearing
    loss and are annoyed by the sources of noise present at the public transportation.

    OBJECTIVE: This study aimed to determine the challenges faced by individuals with hearing loss at a time when many nations were attempting to move from the COVID-19 pandemic to endemic.

    DESIGN: A cross-sectional survey was conducted on Malaysian adults with hearing loss to determine the impact of the COVID-19 crisis on hearing aid management, communication difficulties, psychosocial challenges, and access to audiological services.

    STUDY SAMPLE: One hundred forty-six individuals aged 18 years old and above with hearing loss were recruited from hearing health care centers to participate in the survey.

    RESULTS: Many of the participants (54.2%) reported significant difficulties communicating with people wearing face masks. For hearing aid management, repairing (36.3%) and fine-tuning devices (30.2%) were considered more challenging than obtaining a battery (21.3%). The COVID-19 pandemic had a serious psychosocial impact on a small portion of the individuals surveyed. Remote services were rarely offered by the audiologists, and most participants preferred in-person treatment. However, the majority perceived that creating awareness and training on telehealth was important.

    CONCLUSIONS: Effective management for people with hearing loss needs to consider the challenges faced by them, as the world prepares to live with the coronavirus. Clinical protocols should consider providing a service that is helpful for the clients as well as safe and sustainable in future pandemics.

    BACKGROUND: Maintenance of oral health of children with special needs requires the involvement of caregivers who are also responsible for ensuring adherence to professional recommendations, including dental visits.

    AIM: This study aimed at exploring the correlates of dental visits of children with hearing loss (CWHL) in Indonesia using the theory of planned behaviour (TPB).

    DESIGN: This cross-sectional study involved purposive sampling methods, conducted via an online survey administered to mothers of CWHL who were aged 5-12 years. Constructs of the TPB model were collected, including the mother's attitudes, subjective norms, perceived behaviour control (PBC) and intention towards dental visits for CWHL. Dental visits were measured by asking whether their children had a dental visit within the last 12 months. Data were analysed using SPSS for descriptive and bivariate analyses. The significance level was set as p  .05). Intention did not significantly predict the mother's behaviour towards children's dental visits (p > .05).

    CONCLUSION: The TPB model revealed a construct associated with dental visit intention and behaviour in CWHL. This study suggested that effective promotion intervention should focus on the mother's PBC to increase parents' adherence to preventive dental visits in CWHL in Indonesia.

    AIMS/HYPOTHESIS: Identifying risk factors for tinnitus could facilitate not only the recommendations for prevention measures, but also identifying potential pathways for new interventions. This study reports the first comprehensive systematic review of analytical observational studies able to provide information about causality (i.e., case-control and cohort designs).

    METHODS: A literature search of four electronic databases identified epidemiological studies published on tinnitus and different exposures. Independent raters screened all studies, extracted data, and evaluated study quality using the Newcastle-Ottawa Scale. Reported relative risks (RR), hazard ratios (HR), odds ratios (OR), and prevalence ratios (PR) with 95% confidence intervals (CI) were used to compute crude estimates of RR for tinnitus risk factors.

    RESULTS: From 2389 records identified, a total of 374 articles were read as full text (24 reviews, 301 cross-sectional studies, 42 cohort studies, and 7 case-control studies). However, from 49 case-control and cohort studies, only 25 adequately reported risk ratios. Using the findings from these studies, positive causal associations were found for various hearing-related factors (i.e., unspecified hearing loss, sensorineural hearing loss, occupational noise exposure, ototoxic platinum therapy, and otitis media). Evidence was also found for a number of non-otological risk factors including temporo-mandibular joint disorder, depression, chronic obstructive pulmonary disease, and hyperlipidemia. Negative associations indicating preventative effects were found for diabetes and high alcohol consumption. No associations were found for low alcohol consumption, body mass index, head injury, heart failure, hypertension, leisure noise exposure, migraine, rheumatoid arthritis, sex, smoking, stroke, and whiplash. However, with the exception of unspecified hearing loss, these findings resulted from pooling no more than 4 studies, illustrating that the vast majority of the associations still remain inconclusive.

    CONCLUSIONS: These systematic review and meta-analysis confirm a number of otological and non-otological risk factors for tinnitus. By highlighting major gaps in knowledge, our synthesis can help provide direction for future research that will shed light on the pathophysiology, improve management strategies, and inform more effective preventions.

    This study aims to develop two alternate forms for Malay version of Auditory Verbal Learning Test (MAVLT) and to determine their equivalency and practice effect. Ninety healthy volunteers were subjected to the following neuropsychological tests at baseline, and at one month interval according to their assigned group; group 1 (MAVLT - MAVLT), group 2 (MAVLT - Alternate Form 1 - Alternate Form 1), and group 3 (MAVLT - Alternate Form 2 - Alternate Form 2). There were no significant difference in the mean score of all the trials at baseline among the three groups, and most of the mean score of trials between MAVLT and Alternate Form 1, and between MAVLT and Alternate Form 2. There was significant improvement in the mean score of each trial when the same form was used repeatedly at the interval of one month. However, there was no significant improvement in the mean score of each trial when the Alternate Form 2 was used during repeated neuropsychological testing. The MAVLT is a reliable instrument for repeated neuropsychological testing as long as alternate forms are used. The Alternate Form 2 showed better equivalency to MAVLT and less practice effects.

    A 3-year-old child presented with congenital bilateral facial nerve palsy with bilateral profound sensorineural hearing loss. High Resolution Computed Tomogram (HRCT) of the temporal bones found bilateral atresia of cochlear nerve canals, incomplete partition of the cochleae and narrow facial nerve canals. Magnetic resonance imaging (MRI) revealed bilateral hypoplasia of facial nerves and aplasia of both vestibulocochlear nerves. There have been no other reported cases with this presentation. The possible aetiology and treatment options for the patient are discussed. We highlighted the review of aplasia/hypoplasia of the facial nerve and hypoplasia of cochlear nerve canal.

    The importance of universal newborn hearing screening (UNHS) in identifying hearing-impaired infants as early as possible is already well recognized. Transient evoked otoacoustic emissions (TEOAE) have been established as a reliable method for UNHS in full term infants. This is a cross sectional study between April 2003--December 2005. Thirteen thousand five hundred and ninety eight (13,598) newborns were screened for hearing loss with portable otoacoustic emission (OAE) before discharge. The initial coverage rate during the 3 years study period was 85.9% (13,598) with 89.2% (3762), 79.0% (4480) and 90.3% (5356) for 2003, 2004 and 2005 respectively. The mean age when hearing loss was diagnosed using ABR were 3.56 months old, 3.08 months old, and 2.25 months old and 3.01 months old for 2003, 2004, 2005 respectively and it was statistically significant. The defaulter rate at the third stage during the 3 years study period was 35% (21), 15.2% (7) and 18.2% (2) for 2003, 2004 and 2005 respectively. This study showed significant improvement in initial referral rate, coverage rate and age of diagnosis. However, we need to improve on high defaulter rates.

    A study of 128 jaundiced term neonates showed that 28 (22 per cent) had hearing loss based on brain stem-evoked response. There was no significant difference in the percentage of neonates with hearing loss between those with peak serum bilirubin levels of less than 340 mumol/l (16 per cent) and those with hyperbilirubinaemia > 339 mumol/l (33 per cent) (P = 0.11). Logistic regression analysis showed that severe jaundice which required exchange transfusion and earlier age of onset of hyperbilirubinaemia were statistically significant risk factors associated with hearing loss (P = 0.038 and P = 0.012, respectively).

    A cross sectional study to determine the prevalence of hearing loss and hearing impairment was conducted on 286 male subjects from a rural area. The sample was chosen by using a simple random sampling method. Prevalence of symptoms of tinnitus, ear disease, ear drum perforation and infection of external auditory meatus was 19.0 per cent, 6.7 per cent, 3.5 per cent and 0.4 per cent respectively. Air conduction audiometry tests showed the prevalences of hearing impairment of the left, right and both ears (aged 15-30 years) were 5.9%, 8.8% and 0% respectively. The prevalence of hearing loss increased with age. The higher frequencies (> 4KHz) appeared to be more affected than the lower frequencies.

    INTRODUCTION: Cochlear implantation (CI) in cases with chronic otitis media (COM) was previously contraindicated but recent advances have made it possible.

    OBJECTIVE: To review surgical and audiological outcomes of COM patients that underwent CI.

    MATERIAL AND METHODS: Retrospective review of patients above 18 years old.

    RESULTS: Ten patients with complete data were included. Patients were aged 24-69 years old. Tympanoplasty and mastoidectomy were performed before CI. Imaging was performed to rule out ossifications. Eight patients underwent a standard canal wall up with either cochleostomy or round window approach. One patient had additional canalplasty and tympanoplasty and another one had blind sac procedure respectively. Analysis of the hearing aided level with CI and hearing aid showed significant benefit provided by the CI (Z = 2.803, p = .005).

    DISCUSSION: Creating a dry and safe ear is important prior to CI. Definite hearing improvement is seen in all our cases that helped them to become independent again in their daily life. Hearing aid usage pre-CI might not be important as the hearing aids may continue to cause discharging ears and the benefits of hearing aids in severe to profound hearing loss are very minimal.

    CONCLUSIONS: Cochlear implant is safe and effective in COM patients.

    INTRODUCTION: Congenital cholesteatoma (CC) of the middle ear is a rare entity that may be undiagnosed for years. The lesion can grow undetected until it produces symptoms such as reduced hearing or otalgia.

    METHOD: Case report.

    RESULTS: We report two cases of young ladies with CC who presented with different otological symptoms. The first case complained of recurrent unilateral ear pain while the second case presented with unilateral reduced hearing. Examination of both cases revealed a whitish mass seen behind an intact tympanic membrane. Both cases underwent surgery and histopathological examinations; findings were consistent with cholesteatoma.

    CONCLUSION: There are varieties of clinical presentations of CC and the diagnosis is based on clinical findings.

    Garis panduan saringan telinga tengah oleh American Speech-Language-Hearing Association (ASHA) telah menyarankan agar pendekatan kuantitatif digunakan untuk menginterpretasi keputusan timpanogram. Berbanding pendekatan kualitatif yang digunapakai untuk menginterpretasi timpanogram sebelum ini, pendekatan kuantitatif adalah lebih sesuai kerana ianya bersifat objektif serta dapat diaplikasi dengan peralatan timpanometer komersial yang terdapat di pasaran sekarang. Kajian ini bertujuan untuk mendapatkan nilai mutlak ciri timpanometri iaitu puncak statik admitan akustik dikompensasi (Puncak Ytm), kelebaran timpanogram (TW) dan isipadu salur telinga luar (Vea) di kalangan kanak-kanak pra-sekolah normal dan Sindrom Down. Lima belas kanak-kanak normal dan 12 kanak-kanak Sindrom Down yang memenuhi kriteria pemilihan subjek terlibat di dalam kajian ini. Nilai purata Puncak Ytm dan Vea bagi kanak-kanak normal masing-masing adalah 0.36 mmho dan 0.57 cm3 manakala kanak-kanak Sindrom Down mencatat nilai purata 0.14 mmho dan 0.38 cm3. Kanak-kanak normal dan Sindrom Down masingmasing mencatatkan nilai purata TW 99.73 dan 148.65 daPa. Analisis statistik menunjukkan terdapat perbezaan yang signifikan di antara kedua-dua kumpulan subjek bagi ketiga-tiga nilai parameter timpanometri yang diperolehi.
