Abstract
Introduction: Definition of noise are varied, but generally any sound that is unwanted and may cause annoyance to the receiver is called as noise. The issues and concern regarding noise exposure has been expanded globally through industries that incorporate the use of noise inducing machineries. Noise-Induced Hearing Loss (NIHL) has been recorded as the highest prevalence of Occupational Diseases and Poisoning cases in 2018. Objective: This study aimed to study the level of KAP on occupational noise exposure among the ambulance drivers. Methodology: Cross-sectional study was conducted at four public hospitals in Klang Valley by random sampling. A total of 82 ambulance drivers were enrolled in this study through universal sampling and were required to answer a set of questionnaires modified from previous study consisting of five sections to assess the level of KAP on occupational noise exposure. A Solo 01dB Sound Level Meter was used to measure the level of noise emitted from the siren of the ambulance at the driver's compartment. Three real time measurements were taken to obtain the average noise level at only one hospital as representative. Then, the data analysis was performed by using SPSS version 22. Result and Discussion: The results showed that the noise level in the ambulance ranged from 88.5-90.6 dB (A). There was no regulation related to permissible exposure level for emergency vehicle drivers in Malaysia. However, the reading was already in the range of the current permissible exposure limit based on Factories and Machinery (Noise Exposure) Regulations 1989 which is 90 db (A). There was a significant relationship between knowledge and attitude and the result showed a fair correlation between them (p=0.002, r=-0.339). However, there was no significant relationship shown between know ledge and practice and the results showed a poor correlation between them (p=0.985, r=-0.002). For attitude and practice, there was also no significant relationship shown and resulting in a poor correlation (p=0.062, r=-0.207). There was also no correlation shown between years of employment with level of KAP. The level of KAP on occupational noise exposure among respondents were moderate. Conclusion: In conclusion, training and seminars on occupational noise should be made frequently to ensure high level of KAP of the respondents. Besides, few engineering control such as noise barrier were advised to be implemented and enforcement of law should be taken seriously to minimize and void hearing related problems in the near future. Keywords: Knowledge, attitude, practice, occupational noise exposure, ambulance drivers
