| dc.description.abstract | Noise in industrial area has long been a concern and a problem in the workplace. Noise is an
occupational health problem that always arises in large industries, especially in the work
environment. Noise causes hearing loss in every country in the world and is regarded as one of
industrial pollutants. Hearing loss in the workplace includes traumatic acoustic injuries and hearing
loss caused by Noise Induced Hearing Loss (NIHL) which can be defined as partial or complete
hearing loss in one or both ears as a result of work. Excessive noise exposure is the leading cause of
permanent hearing loss worldwide. Therefore, we are interested in conducting this research due to
the lack of research data or information about the relationship between duration of working and
hearing loss in workers at furniture factories, Tanjung Morawa District, Deli Serdang Regency.

Result: In this study, of the 35 workers with duration and normal hearing on the
left ear were 3 people (100%), while working duration > 10 years with normal hearing on the left
