The Impact

Although hearing is known to play an essential role in military operations, few studies have directly measured the impact of hearing loss on combat effectiveness. In this study, Soldiers from the 101st Airborne were equipped with hearing loss simulators allowing parametric adjustment of hearing between normal and profound deafness. They then participated in a combat exercise requiring multiple fire teams with different levels of hearing loss to progress through a series of waypoints in a wooded area as quickly as possible without being eliminated by enemy gunfire. A GPS-based tracking system made it possible to record the progress of each team throughout the exercise, including information on player eliminations and the players credited with these kills. Results show that hearing impairment has a substantial negative impact on the performance of experienced Soldiers in terms of survivability, lethality, and mission success.

The Impact

The purpose of this chapter is to review the literature on hearing impairment, specifically the impact of hearing impairment on the functioning of elders, interventions that minimize the impact of hearing loss on functioning, and identification of issues raised by the review for nursing research. Computerized (MEDLINE, PsychINFO, and CINAHL) and manual searches were used to obtain research reports from a range of disciplines. Research articles including elders (≥ 60) and published between 1989 and 2001 were included. Twenty-five articles were selected for critical review, four written by nurses. The diversity of methodologies, the criteria used to define hearing impairment, the range of sample characteristics, and the assessment measures make comparisons across studies difficult. Most studies, however, support the negative impact of hearing impairment, especially on psychosocial functioning. Measures that are condition specific are generally more effective in capturing the impact of hearing loss than generic measures. Findings related to physical disability are less consistent. The results of intervention studies suggest that hearing devices can improve psychosocial and communication outcomes, but behavioral interventions have not shown long lasting benefit. For nurses to assist elders and their families manage the impact of hearing impairment, further research is needed in several areas that have been poorly explored. These include the dyadic experience of hearing impairment, the way in which culture influences the experience of hearing loss, the needs of hearing impaired individuals across settings, the long-term impact of ototoxic medications, and strategies to assist elders in coping with hearing impairment and utilizing available technologies.

Introduction/Objective. Presbycusis, elderly hearing loss, is a progressive, bilateral sensoryneural hearing loss characterized by reduced sensitivity of hearing and understanding speech in a noisy environment, thereby impairing communication and inducing anxiety. The objective was to examine the impact of hearing amplification on subjective hearing disability assessment and anxiety in people with presbycusis. Method. Sample consisted of 120 respondents aged 47?85 with presbycusis, 60 subjects with and 60 subjects with no auditory amplification. The standardized Hearing Handicap Inventory for the Elderly and the Spielberger State Trait Anxiety Inventory were used in the study. Results. In subjects with hearing amplification, test/retest has no statistical significance in the STAI and HHIE scales and subscales, except the HHIE-S (p = 0.004) with a lower score on the retest. Respondents in whom hearing amplification was performed during the year was statistically significant in HHIE (p = 0.016), HHIE-S (p = 0.004) and STAI-S (p = 0.029) which speaks of favorable effect of hearing amplification. In the group with no hearing amplification, statistical significance was observed in relation to the HHIE scores (p = 0.002), HHIE-E (p = 0.000), STAI (p = 0.000), STAI-S (p = 0.001) and STAI-T (p = 0.001) and it was noticed that anxiety, loss of emotional contacts, and more pronounced degree of hearing impairment were the result of unassisted hearing rehabilitation. Conclusion. Audiological practice should include tests for assessment of hearing disability and anxiety in order to preserve health in later life.

Byzantine Attacks

Herein, the problem of target tracking in wireless sensor networks (WSNs) is investigated in the presence of Byzantine attacks. More specifically, we analyze the impact of Byzantine attacks on the performance of a tracking system. First, under the condition of jointly estimating the target state and the attack parameters, the posterior Cramer–Rao lower bound (PCRLB) is calculated. Then, from the perspective of attackers, we define the optimal Byzantine attack and theoretically find a way to achieve such an attack with minimal cost. When the attacked nodes are correctly identified by the fusion center (FC), we further define the suboptimal Byzantine attack and also find a way to realize such an attack. Finally, in order to alleviate the negative impact of attackers on the system performance, a modified sampling importance resampling (SIR) filter is proposed. Simulation results show that the tracking results of the modified SIR filter can be close to the true trajectory of the moving target. In addition, when the quantization level increases, both the security performance and the estimation performance of the tracking system are improved.

Background: This study compares the mental health and psychological response of students with or without hearing loss during the recurrence of the COVID-19 pandemic in Beijing, the capital of China. It explores the relevant factors affecting mental health and provides evidence-driven strategies to reduce adverse psychological impacts during the COVID-19 pandemic. Methods: We used the Chinese version of depression, anxiety, and stress scale 21 (DASS-21) to assess the mental health and the impact of events scale—revised (IES-R) to assess the COVID-19 psychological impact. Results: The students with hearing loss are frustrated with their disability and particularly vulnerable to stress symptoms, but they are highly endurable in mitigating this negative impact on coping with their well-being and responsibilities. They are also more resilient psychologically but less resistant mentally to the pandemic impacts than the students with normal hearing. Their mental and psychological response to the pandemic is associated with more related factors and variables than that of the students with normal hearing is. Conclusions: To safeguard the welfare of society, timely information on the pandemic, essential services for communication disorders, additional assistance and support in mental counseling should be provided to the vulnerable persons with hearing loss that are more susceptible to a public health emergency.

Background: Hearing loss (HL) in adults is loss of ability to perceive surrounding environmental sounds. There may be environmental or genetic cause of this disability. Presently expectancy of old adult age is going to increase as in the same way hearing problems and its negative impact on health wellbeing standard of living also increased, the beneficial of current study is to be addressed, or give awareness about health consequences to adult population with hearing impairment. Aim: To determine the quality of life in adults with hearing impairment. Place and Duration of Study: Riphah international University, Lahore campus between December 2018 to May 2019. Methodology: A cross sectional survey was conducted on 67 adults with hearing impairment (sample size was calculated on the base of prevalence of hearing loss in the Express Tribute, (March 4, 2014) which was a Pakistani  study on hearing impaired  population  the president of famous organization the  developmental diseases and community of auditory handicap  MR Afzal  estimated the   occurrence of auditory deficits  in Pakistan region was in between  7 to 8 percent on per 10,000 living birth ,this prevalence was used to calculate sample size by using online calculator).(1), their age range were 18 to 55 (elder adults) and 56 to 97(older adults). Data collection tool which was used in this research was 15D Quality of life questionnaire to find out the influence of hearing loss (HL) on daily living activities in adult’s life. Sampling technique used in this research was convenient sampling. For this purpose, descriptive analysis was done for demographics and chi square was used for inferential analysis by using SPSS20. Endnote was used for references. Results: There are four domains of quality of life (speech, usual activities, mental functioning, and vitality status of participants) which have highly significant relationship value(<0.001) with hearing impairment, in other domains of quality of life p value is less then (<0.05) this means that other domains of quality of life have also significant relationship with hearing impairment except visual or sexual activity of the participants which have no significant association p- value(>0.05)with hearing impairment. Conclusion:  Research concluded that domains of quality of life are significantly associated with hearing loss which have negative impact on the QOL(quality of life) except visual or sexual activity, but these two domains may also indirectly have associated or may affect the quality of life individually in adults with hearing impairment.

Background: Hearing impairment is highly prevalent in older adults and can affect the daily activities of a person who is hard of hearing (HOH). The impact of hearing impairment may also have collateral effects on the primary communication partner (CP; e.g., spouse, close family member, or caregiver) of the person who is HOH. Purpose: We aimed to characterize the impact of hearing loss in a person who is HOH on his or her CP. Research Design: We conducted a systematic review of manuscripts examining the consequences of hearing loss in a person who is HOH on the CP. We searched PubMed, Embase, Scopus, PyscINFO, CINAHL Plus with full text, and Web of Science for peer-reviewed articles using a predefined search string and hand-searched reference lists of relevant articles. Data Collection and Analysis: We initially screened abstracts blinded for author and journal to eliminate irrelevant and duplicate articles. Descriptive information on study populations, hearing assessments, outcome metrics, and study findings were extracted from full-length manuscripts. Results: Of the 1,047 abstracts retrieved from database searching and 5 hand-searched articles, 24 articles met inclusion criteria. These articles included observational clinical studies, randomized clinical trials, and epidemiologic studies. Overall, CPs experienced a restricted social life, increased burden of communication, and poorer quality of life (QOL) and relationship satisfaction. Effects of hearing impairment on a CP’s mental health were unclear. Treatment of hearing loss in the person who is HOH tended to improve QOL, communication, feelings toward the person who is HOH, and activity participation of the CP. Conclusions: This review highlights the broad effects of hearing impairment and the importance of involving CPs in hearing loss treatment decisions.

The Caucasian war had a significant impact on both the internal and the external migration situation in Dagestan. First noticeable negative impact made war on internal seasonal movement of highlanders to the plains to exchange goods, livestock and handicrafts, and seasonal movements of the relatively large proportion of the adult male population in search of work to the plains of Dagestan. One of the consequences of the national liberation movement 1820–1850s of the mountaineers of Dagestan there was a mass migration of highlanders who did not want to participate in the Caucasian war in the Caucasus. The most severe effects were villagers caught in the crossfire. Military operations and their accompanying destruction of villages, forced inhabitants to move to other areas, the result of forced migration have changed the boundaries of the settlement of peoples.

Abstract Background The prevalence of otitis media (OM) and related hearing loss has remained persistently high among some groups of Australian Aboriginal children who are also reported to have poor academic outcomes. The general literature remains inconclusive about the association between OM-related hearing loss and academic performance in primary school. This study aimed to investigate this association in Aboriginal children living in the Northern Territory (NT) of Australia. Methods A retrospective, observational cohort study was conducted for 2208 NT Aboriginal children, aged about 8 years, living in remote and very remote communities. The explanatory variable was audiometrically determined hearing level as recorded in the Remote Hearing Assessment dataset. The outcome variable consisted of scale scores in the five domains of the National Assessment Program – Literacy and Numeracy (NAPLAN) for Year 3. Other linked datasets used in the study included school attendance records, perinatal records and community level information on relative remoteness, socioeconomic disadvantage and housing crowdedness. Fixed effects linear regression models were used for statistical analyses. Results Compared with children with normal hearing and after controlling for a range of covariates, children with mild hearing impairment (HI) scored lower in Writing and Spelling by 15.0 points (95% CI: − 22.4 to − 7.6, p < 0.0005) and 5.0 points (95% CI: − 9.6 to − 0.3, p = 0.037), equivalent to 7.3 and 2.1% of the mean score, respectively. Children with moderate or worse HI scored lower in Writing and Numeracy by 13.4 points (95% CI, − 24.8 to − 1.9, p = 0.022) and 15.2 points (95% CI, − 27.6 to − 2.7, p = 0.017), both equivalent to 6.3% of the mean score the respective domain. Other factors associated with poorer NAPLAN results included being male, lower Year 2 school attendance, low birthweight, average household size> 5 persons, living in a very remote community and speaking English as a second language. Conclusions OM-related HI was independently associated with poorer early year academic achievement in Aboriginal children living in remote NT communities. Interventions to improve academic outcomes for Aboriginal children must incorporate actions to address the negative impact associated with HI through early detection, effective treatment and ongoing support for affected children.

Gangguan pendengaran pada anak usia dini mempengaruhi proses perkembangan anak. Dampak yang ditimbulkan menyebabkan gangguan dalam berbahasa, perubahan kepribadian, sikap, kemampuan berkomunikasi, kepekaan terhadap lingkungan, kemampuan kognitif, emosional dan kemampuan untuk melindungi diri sendiri. Gangguan ini disebabkan oleh faktor genetik maupun non genetik yang dapat muncul sejak lahir maupun di atas usia tiga tahun. Bayi yang memiliki riwayat kesehatan kurang baik cenderung memiliki gangguan pendengaran dibandingkan dengan bayi yang memiliki riwayat kesehatan yang sehat.  Deteksi dini gangguan pendengaran perlu dilakukan pada anak usia dini sehingga pemberian intervensi lebih awal dapat dilakukan apabila ditemukan adanya gangguan pendengaran. Deteksi dan rehabilitasi dini yang tepat dapat meningkatkan perkembangan bicara dan berbahasa anak. Keterlambatan dalam melakukan deteksi dini akan menimbulkan keterlambatan untuk memulai intervensi dan berdampak negatif dalam perkembangan anak selanjutnya. Deteksi gangguan pendengaran  dilakukan dengan menggunakan rangsangan bunyi sejak bayi dan menggunakan alat audiometer pada anak usia di atas 48 bulan sesuai dengan tahapan pertumbuhan dan perkembanganya. Deteksi dini gangguan pendengaran  dilakukan dengan cara mengamati reaksi anak terhadap suara atau tes fungsi pendengaran dengan metode dan peralatan yang sederhana. Deteksi ini dapat dilakukan oleh guru, tenaga kependidikan, orang tua ataupun petugas kesehatan Kata kunci: deteksi gangguan pendengaran, usia dini Hearing loss in early childhood affects the child's development process. The impact caused by language disorders, changes in personality, attitudes, communication skills, sensitivity to the environment, cognitive abilities, emotional and ability to protect yourself. The purpose of this study is to explain the detection of hearing loss in early childhood. The research method used is descriptive literature research. The results of this study stated that hearing loss in early childhood is caused by genetic and non-genetic factors that can arise from birth or over the age of three years. Babies who have a poor health history tend to have hearing loss compared to babies who have a healthy health history. Early detection of hearing loss needs to be done in early childhood so that early intervention can be given if hearing loss is found. Appropriate early detection and rehabilitation can improve children's speech and language development. Delay in early detection will cause delays to start interventions and have a negative impact on further child development. Detection of hearing loss is carried out using sound stimulation since infancy and using an audiometer in children over 48 months according to their stages of growth and development. Early detection of hearing loss is done by observing the child's reaction to sound or hearing function tests with simple methods and equipment. This detection can be done by teachers, education personnel, parents or health workers. Keywords: detection of hearing loss, early childhood

Introduction With increasing life expectancy globally, hearing loss has become a major issue of concern. In addition to the negative implications on the people with hearing loss, it is also found to have a significant negative impact on the communication partners especially the spouse. Understanding the impact of hearing loss on their partners can aid us in addressing these issues during rehabilitation. Materials and Methods A cross sectional study was conducted among 60 people who presented with hearing loss and were living with their spouse. The hearing loss was assessed using pure tone audiometry. The third party disability among the spouses was assessed by using HII-SOP questionnaire. The disability scores were calculated and correlated with the severity of hearing loss using chi square test. Results The hearing loss was associated with some degree of third party disability (58.3%). The degree and duration of hearing loss did not correlate with the degree of third party disability. Female significant others had more difficulty than the male significant others. However, increasing age of the spouse, longer duration of married life and presence of chronic illness in the spouse were associated with more third party disability.  Conclusion Hearing loss causes third party disability among spouses. In addition to treating hearing loss, the health care professionals should involve the spouses in treatment and rehabilitation. This highlights the need for family centred policies in treatment of hearing loss.
