However, in the Technical Division at 08.00 – 16.00 was averagely between 88,3 – 90.9 dBA, at 16.00 – 24.00 was between 89.3 – 93.5 dBA and at 24.00 – 08.00 was between 69.9 – 73.2 dBA. Hearing acurity of ground handling staff in the administration division was 1 personnel (16.7 %) experienced hearing acurity depreciation.
