The line maintenance jobs include regular checks on aircraft transit, refueling, troubleshooting etc. in order to maintain aircrafts’ airworthiness. This job site is located at the aircraft apron where the noise exceeds 85 dBA due to the frequent take-off and landing by aircrafts. According to the Occupational Safety and Health Act, it is considered as noise hazard area. Consequently, it is very likely to cause occupational hearing loss if workers are exposed to noise in excess of an exposure limit without wearing hearing protection. In order to understand the patterns of hearing loss for ramp workers, this study applying Hierarchical Linear Modeling to analyze the hearing test data of an airline basing on Taoyuan International Airport for five consecutive years. The results of this study can provide employers a reference with respects to hearing screening for new employees and hearing protection for aircraft maintenance workers. Additionally, the study can be used as a training material for these workers as to reinforce the hearing protection.
