    Audiograms are used to show the hearing capability of a person at different frequencies. The filter bank in a hearing aid is designed to match the shape of patients' audiograms. Configuring the hearing aid is done by modifying the designed filters' gains to match the patient's audiogram. There are few problems faced in achieving this objective successfully. There is a shortage in the number of audiologists; the filter bank hearing aid designs are complex; and, the hearing aid fitting process is tiring. In this work, a machine learning solution is introduced to classify the audiograms according to the shapes based on unsupervised spectral clustering. The features used to build the ML model are peculiar and describe the audiograms better. Different normalization methods are applied and studied statistically to improve the training data set. The proposed Machine Learning (ML) algorithm outperformed the current existing models, where, the accuracy, precision, recall, specificity, and F-score values are higher. The reason for the better performance is the use of multi-stage feature selection to describe the audiograms precisely. This work introduces a novel ML technique to classify audiograms according to the shape, which, can be integrated to the future and existing studies to change the existing practices in classifying audiograms.

    Suboptimal hearing aid use negatively impacts health and well-being. The aim of this study was to conduct a controlled trial of a behavior change intervention to promote hearing aid use. This study was a quasi-randomized controlled trial with two arms. A total of 160 first-time hearing aid users were recruited at their hearing aid fitting appointments. The control arm received standard care. In addition to standard care, the intervention arm received I-PLAN, which comprised (a) information about the consequences of hearing aid use/nonuse, (b) reminder prompt to use the hearing aids, and (c) an action plan. The primary outcome, measured at 6 weeks, was self-reported proportion of time the hearing aid was used in situations that caused hearing difficulty. Secondary outcomes were data-logged hearing aid use, self-reported hearing aid benefit, self-regulation, and habit formation. The results showed that the proportion of time the hearing aids were used in situations that caused hearing difficulty was similar in both groups. There were no statistically significant differences between groups in any outcome measure including data-logged hearing aid use. The relatively high levels of hearing aid use across research participants may have limited the potential for the intervention to impact on hearing aid use. Although the intervention materials proved acceptable and deliverable, future intervention trials should target suboptimal hearing aid users.

    INTRODUCTION: The Joint Committee of Infant Hearing (JCIH) recommended hearing screening by one month of age, diagnosis of hearing loss by three months of age, and intervention initiated by six months of age. In Malaysia however, the age of diagnosis of hearing loss in children is relatively late. This study aimed to identify the challenges faced by parents in seeking a diagnosis of hearing loss for their children.

    METHOD: The study utilized a semi-structured interview with open-ended questions to obtain information about parents' experiences during the diagnosis period and their challenges when going through that process. In this study, a total of 16 parents of children who were diagnosed with moderate to profound sensorineural hearing loss and received intervention within three years at the time of the study participated. Ten of the children were cochlear implant users, and six were hearing aid users.

    RESULTS: Thematic analysis was used to analyse themes generated from the data according to the study objective. Four main themes and 17 subthemes were identified from this study. The four main themes were 1) Parents' emotion; 2) Parental knowledge; 3) Others; 4) Profesional services. Challenges that parents faced often include emotional behaviours such as feeling guilty and devastated during the diagnosis, lack of information-sharing from healthcare givers, lack of knowledge on childhood hearing loss among parents, support from families, seek for a second opinion, worry about others' acceptance, longer time for diagnosis to confirm, late referral to other related profesionals and no priority for the appointment.

    CONCLUSION: Emotion is identified as the biggest challenge faced by parents in the process of diagnosis for their children with hearing loss. Hence, management of parental emotion needs to be emphasized by health profesionals as it influences the acceptance of parents towards their child's diagnosis.

    The Vibrant Soundbridge is a new middle ear implantable hearing device. It was first introduced for adult patients with moderate to severe sensorineural hearing loss. With the innovation of the surgical techniques, its usage had been broadened for children and those patients with conductive and mixed hearing loss. We report first two cases of monoaural Vibrant Soundbridge implantation in Malaysia. They were children with bilateral conductive hearing loss who had failed to benefit from previous hearing aids. Floating mass transducers were attached in oval window and long process of incus respectively. Remarkable hearing yield was observed without surgical complication.

    Hearing impairment is one of the most important health problems of the elderly above 60. Very often it leads to verbal communication difficulty and without treatment it can cause serious psychological and social complications such as depression and social isolation. Prebyscusis remains a leading cause of sensorineural deafness in the elderly. Elderly patient must be encouraged to seek proper hearing assessment if they face hearing difficulty. Active screening by health care workers and patient self-evaluation by answering a simple list of screening questions are possible for early detection and treatment of hearing loss in the elderly. Although hearing loss in the elderly may not have a cure, early rehabilitation helps to restore better quality of life if the problem is detected early.

    The use of headphone has been thought to cause infection in the ear canal and contribute to hearing loss. In this study, we examined 136 Customer Service Representative from Celcom (Malaysia) Sdn. Bhd. who use headphone throughout their working hours. The purpose of this study was to determine the prevalence of ear canal infection and other related diseases of the ear, nose and throat. Their hearing thresholds were also determined using the Amplaid 309 Clinical Audiometer. We found no incidence of infection of the external ear canal amongst the subjects. There were 4 cases of chronic middle ear infection and 4 cases of impacted wax. Hearing impairment was found in 25 subjects (21.2%). However, there was no significant association between hearing loss and the exposure to sound from headphone usage because the high frequencies were not predominantly affected. There was also no association between hearing loss and duration of service.

    Sensorineural hearing loss following trauma is a common finding in daily clinical practice and usually associated with a poor prognosis. Our case illustrates a patient who was involved in motor vehicle accident sustaining bilateral severe to profound sensorineural hearing loss but subsequently recovered fully after two years. Unless there is clear trauma to the cochlea or auditory nerve, a substantial duration of follow up is needed in the treatment of such cases.

    PURPOSE: Single-microphone noise reduction (SMNR) is implemented in hearing aids to suppress background noise. The purpose of this article was to provide a critical review of peer-reviewed studies in adults and children with sensorineural hearing loss who were fitted with hearing aids incorporating SMNR.

    METHOD: Articles published between 2000 and 2016 were searched in PUBMED and EBSCO databases.

    RESULTS: Thirty-two articles were included in the final review. Most studies with adult participants showed that SMNR has no effect on speech intelligibility. Positive results were reported for acceptance of background noise, preference, and listening effort. Studies of school-aged children were consistent with the findings of adult studies. No study with infants or young children of under 5 years old was found. Recent studies on noise-reduction systems not yet available in wearable hearing aids have documented benefits of noise reduction on memory for speech processing for older adults.

    CONCLUSIONS: This evidence supports the use of SMNR for adults and school-aged children when the aim is to improve listening comfort or reduce listening effort. Future research should test SMNR with infants and children who are younger than 5 years of age. Further development, testing, and clinical trials should be carried out on algorithms not yet available in wearable hearing aids. Testing higher cognitive level for speech processing and learning of novel sounds or words could show benefits of advanced signal processing features. These approaches should be expanded to other populations such as children and younger adults. Implications for rehabilitation The review provides a quick reference for students and clinicians regarding the efficacy and effectiveness of SMNR in wearable hearing aids. This information is useful during counseling session to build a realistic expectation among hearing aid users. Most studies in the adult population suggest that SMNR may provide some benefits to adult listeners in terms of listening comfort, acceptance of background noise, and release of cognitive load in a complex listening condition. However, it does not improve speech intelligibility. Studies that examined SMNR in the paediatric population suggest that SMNR may benefit older school-aged children, aged between 10 and 12 years old. The evidence supports the use of SMNR for adults and school-aged children when the aim is to improve listening comfort or reduce listening effort.

    The paper writes on the possible origin of off-limit cases found in a noise project conducted internally in a factory in Malaysia. Out of 691 sampled workers’ that attended audiometric test results (some repeated), it was found that the mode of hearing ability is between 20 to 30 dB depending on individual worker’s age ranging from 20 to 55 years. Out of the total results, approximately 100 workers are above a limit defined here in this paper as the off-limit condition. The chance of a worker originating from a good condition to an unhealthy condition is about 1 percent. The data are tabulated to show that a sway pattern could be an explanation of workers’ origin. Although the data is profound, there is no evidence of a trace due to a short test period. Possibilities are highlight here to outline the severity of a cross over to the unhealthy condition (here defined as the off-limit condition). Some advises are mentioned here with individual susceptibility on the matter though there is no data to substantiate. Further findings are required to show a trace. In conclusion, the severity is highlight. A chart, developed to know the limits of hearing ability, is illustrated ased the findings.

    OBJECTIVE: Provision of information is already part of standard care and may not be sufficient to promote hearing aid use. The I-PLAN is a behavior change intervention that is designed to promote hearing aid use in adults. It consists of a prompt, an action plan and provision of information. The objective was to test the effectiveness of the I-PLAN prompt and plan components in promoting hearing aid use and benefit. Hypotheses were: there would be greater hearing aid use, benefit, self-regulation, and hearing aid use habit among participants who received the prompt or plan component, compared with no prompt or no plan component, and the effect would be the greatest in participants who received both prompt and plan; and self-regulation and habit would mediate the effect of prompt and/or plan components on hearing aid use and benefit.

    DESIGN: A 2 x 2 factorial randomized controlled trial design. Two hundred forty new adult patients (60 in each group) were randomized to: information (info) only; info + prompt; info + plan; or info + prompt + plan. All participants received treatment as usual in addition to I-PLAN components, which were provided in a sealed envelope at the end of the hearing aid fitting consultation. Participants in the prompt group were instructed to use their hearing aid box as a physical prompt to remind them to use the device. Participants in the plan group were instructed to write an action plan to encourage them to turn their intentions into action. Participants, audiologists, and researchers were blinded to group allocation. The primary outcome was self-reported proportion of time hearing aids were used in situations where they had listening difficulties. Secondary outcomes were hearing aid use derived from data logging, self-reported hearing aid benefit, self-reported self-regulation, and habit. Outcomes were measured at 6-week post-fitting.

    RESULTS: Contrary to predictions, participants who received the prompt component reported using their hearing aid less than participants without the prompt (p = 0.03; d = 0.24). The mean proportion of time hearing aid were used was 73.4% of the time in the prompt group compared with 79.9% of the time in the no prompt group. Participants who received the plan component reported using their hearing aids more frequently than those who did not receive the plan (Meanplan = 81.0% vs Meannoplan = 71.8% of the time; p = 0.01; d = 0.34). Receiving both prompt and plan components did not change self-reported proportion of time hearing aids were used but data-logging use was significantly reduced. The prompt reduced self-regulation of hearing aid use compared with the no prompt (p = 0.04; d = 0.28), while the plan promoted stronger hearing aid use habits than the no plan group (p = 0.02; d = 0.30).

    CONCLUSIONS: Audiologists should consider using action plans to promote hearing aid use. Despite the decrease in hearing aid use when using the hearing aid box as a physical prompt, hearing aid use was still high (≈70% of the time). The hearing aid box may have slightly reduced hearing aid use by undermining self-regulation. Participants may have delegated responsibility for hearing aid use to the prompt. Subsequent studies should evaluate different prompts and test the long-term benefit of the plan on hearing aid use via habit formation.
