“…The Korean classical music students and firefighters were exposed to the highest L max at 151.8 dBC and 145.8 dBC, respectively, during the practicing and dispatching. These levels exceeded the noise standard of ACGIH (140 dBC) [25]. Given that the noise exposure over 140 dBC could induce temporary hearing loss or other hearing damage, the music students and the firefighters were at a high risk of such impairments [26].…”

Noise is known that the physical risk factors defined as any unwanted sound. It can induce the health problems such as hearing loss or annoyance. The objective of this study was to assess the occupational noise exposure of nine groups for twenty peoples according to job characteristics and to compare the noise level by different variables. Personal noise levels were measured for three times using by dosimeters for each participant in Korea. The mean time weighted average noise level (TWA) of total was 73.2 ± 11.5 dBA by American conference of governmental industrial hygienists (ACGIH) standard. Especially, Korean classical music students were highly exposed to 93.2 ± 6.2 dBA but, office workers were 63.2 ± 6.6 dBA. In case of peak sound pressure level (L<sub>peak</sub>), Korean classical music students and firefighters were exposed to the highest level of 151.8 dBC and 145.8 dBC during playing and dispatching, respectively. The analysis of noise level showed that L<sub>eq</sub> had positive correlations between TWA by ministry of employment and labour (MOEL) (r = 0.98, p < 0.01) and TWA by ACGIH (r = 0.98, p < 0.01). Unlikely other groups, the noise exposure level of the Korean classical music students were exceeded the ACGIH standard. These results suggest that Korean classical music students were exposed high noise level and some solutions are need to reduce the noise exposure level such as using hearing protect device

Studies evaluating the health effects of hazardous air pollutants assume that people's exposure to typical pollutant level is the same as specific regional pollutant level. However, depending on social and demographic factors, time-activity pattern of people can vary widely. Since most people live in indoor environments over 88% of the day, evaluating exposure to hazardous air pollutants is hard to characterize. Objective of this study was to estimate the exposure levels of university students of NO2, VOCs(BTEX) and PM10 using the scenarios with time-activity pattern and indoor concentrations. Using data from time-use survey of National Statistical Office in 2009, we investigated time-activity pattern of university students and hourly major action. A total of 1,057 university students on weekday and 640 on weekend spent their times at indoor house 13.04 hr(54.32%), other indoors 7.70 hr(32.06%), and transportation 2.36 hr(9.83%). Indoor environments in which university students spent their times were mainly house and school. Air pollutants concentrations of other indoor environments except house and school such as bar, internet cafe and billiard hall were higher than outdoors, indicating that indoor to outdoor ratios were above 1. According to three types of exposure scenarios, exposure to air pollutants could be reduced by going home after school.

This study was conducted on firefighters from 11 fire departments located in Jeollabuk-do from October to November of 2020. As determined by the hearing loss screening questionnaire (KHHIE-S), length of time spent working in military services and in the rescue team/Emergency Medical Services (EMS) were found to be factors that significantly affecting hearing loss in the group. The worst four Pure Tone Average (PTA) scores on the screening hearing test were observed in study subjects who were male, and those who had previously worked for extended lengths of time in EMS and/or outside duty. In this study, factors affecting hearing loss in firefighters were identified. This research will hopefully provide an opportunity for the health care community, academia, government, and society in general to learn about and become involved in combatting hearing impairment and hearing loss in this critical profession.
