Abstract

Abstract: Noise, being one of the threats towards occupational health, has exposed 600 million workers globally. The incidence of hearing loss caused by workplace noise is 16% in adults. There are various risk factors of hearing loss. The purpose of this study was to determine the effect of those risk factors on Universal Steel Factory’s workshop workers. This is an analytical study with a cross-sectional design. Data were collected through history taking, physical examination and pure tone audiometry for 30 workers. The data obtained were analyzed using Chi-square and Fisher's exact. There was a correlation between hearing loss with age (p = 0.001), working period (p = 0.001), noise intensity (p = 0.004), and smoking habits (p = 0.013). Therefore, age, working period, noise intensity, and smoking habits have influences to the occurrence of noise-induced hearing loss.Keywords: risk factors, noise-induced hearing loss, workshop workers

Abstract

Abstract : There are 278 million people affected by hearing loss in the world. The absorption of information by listening is greater than reading. Primary school students with hearing loss have difficulty in learning various aspects of verbal communication compared to normal children. The purpose of this study is to determine the relationship between the hearing loss with the achievement of grade 6 students of a primary school. This is an analytical study with a cross-sectional approach to 52 students. The data obtained from physical examination of the ear, tuning fork examination, pure tone audiometry examination, and student’s academic achievement report cards. Hearing function, degree of hearing loss, and academic achievement in each subject are described in descriptive statistics. Fisher exact test is used to find the relationship between hearing loss and academic achievement in every subject at school. There was a significant relationship between hearing loss and academic achievement based on Indonesian subjects (p = 0,013), English (p = 0,026), and mathematics (p = 0,007). There is a significant relationship between the hearing loss and the achievement of grade 6 students of the primary school.Keywords: academic achievement, hearing disorder, primary school
