The Improved of work station to reduce impact of hearing in the group of informal labor 's health case study white grated coconut communities enterprise in Samut Songkhram province

Abstract

This research the objectives of this research are to The Improved of work station to reduce impact of hearing in the group of informal labor 's health case study white grated coconut. In this research, samples are randomly chosen, regardless of probabilities. We perform a specific selection and collect data with hygienic measuring instruments, such as sound and Audiometer. Moreover, this research uses the Interview. The result is analyzed by descriptive statistics, such as frequency, and percentage, and inferential statistics, such as Independent-sample t Tests.

The result shows the study. There were 18 workers with hearing ability at the level of mild deafness at frequencies of 500, 1,000 and 2,000 Hz, and 10 persons with moderate deafness at frequencies of 3,000, 4,000 and 6,000 Hz. The sound assessment found that Outer shelling of coconut Coconut shell work and white coconut shell work exceed the standard Water drilling segment in the standard (TWA8=85dB(A)) When improving the environment and the work station, it was found that the problem of over-sound noise could be solved in 3 tasks, namely, peeling the outer layer. White coconut peeling and water drilling for meat separation, sound levels TWA₈ =79.20dB(A), 75.66dB(A), 73.58dB(A), respectively. For coconut shelling, it was found that it was still above the standard value TWA8 =89.61 dB(A) and could not be changed. how it works Therefore, take a personal protection approach by PPE, noise reduction ear plug type Ear plug foam material NRR=33 noise reduction = 9.5dB(A) noise received while wearing the plug. Ear = 80.11dB(A) is the level within the benchmark.
