Abstract

Population growth can generate various activities that consequently lead to an increase in transportation facilities. This condition is closely associated with the high purchasing power of the community toward motor vehicles as a means of transportation. The increase in the number of motor vehicles has serious environmental impacts, particularly noise pollution. Noise is defined as unwanted sound generated by activities or operations at certain levels and durations that may cause disturbances, thereby interfering with and/or endangering human health. Traffic noise that exceeds permissible standards can result in negative impacts on people conducting activities around the noise source. In general, noise can adversely affect health, causing physiological, psychological, communication, balance disorders, and hearing-related effects. This study aimed to obtain information on noise levels along Malioboro Street in 2021. The research employed a descriptive observational survey design. The study was conducted along Malioboro Street, with samples collected at three observation points: Point I (Malioboro Sign Entrance Gate), Point II (in front of Taman Batik Terang Bulan Store), and Point III (Yogyakarta Zero Kilometer Point). Data collection was carried out for one week. The results showed that traffic density and noise intensity were directly proportional to the noise levels on Malioboro Street, with an average vehicle volume of 1,703.2 units/day and an average noise level of 70 dBA. The study concludes that most of the measurements exceeded the permissible noise standard for commercial and service areas, which is 70 dBA, across the three observation points per day.

Abstract

Industrial environments often generate high noise levels due to the continuous operation of machinery and production equipment. Persistent exposure to workplace noise exceeding the Threshold Limit Value (TLV) can lead to noise-induced hearing loss. According to the World Health Organization, an estimated 430 million people worldwide require rehabilitation for hearing impairment, with 109.4 million of these cases occurring in Southeast and Central Asia. As a critical component of Occupational Health and Safety (OHS) management, noise control is often implemented using Hearing Protection Devices (HPDs). This study aims to evaluate the effectiveness of an earplug-earmuff combination, developed as Madcom Noise Protection, in enhancing noise attenuation and assessing its acceptability among users. Utilizing a quasi-experimental design, the study involved 30 students from Poltekkes Kemenkes Yogyakarta. The results demonstrate that Madcom Noise Protection significantly improved hearing threshold levels by an average of 8.50 dB compared to using an earmuff alone ($p < 0.001$). Furthermore, user acceptability was remarkably high, reaching an average score of 97.33%. In conclusion, the developed earplug-earmuff combination is highly effective in strengthening hearing protection and is well-received as an innovative HPD modification.
