In this study, it is aimed to determine and map the noise pollution levels in Safranbolu District Center, especially in the regions where motor vehicle and/or pedestrian traffic is intense. Forty-seven measurement points were selected for noise level measurements at the district center. Measurements were conducted at morning (8 a.m.-10 a.m.), lunchtime (12 p.m.-2 p.m.) and evening (6 p.m.-8 p.m.) hours of weekdays and weekends throughout the seasons of summer 2017 and winter 2018. The summer season weekdays noise level ranges from 41.3 to 71.2 dBA in the morning period, 40 to 71.2 dBA in the noon period and 40.6 to 73.1 dBA in the evening. The summer season weekend noise level ranges from 45.3 to 69.1 dBA in the morning period, 44.7 to 71.4 dBA in the noon period and 41.6 to 70.9 dBA in the evening. The result showed that the level of summer season weekday and weekend noise pollution in the morning, noon and evening is close to each other. In addition, the winter season weekdays noise level ranges from 32.3 to 68.5 dBA in the morning period, 30.8 to 73.3 dBA in the noon period and 37.4 to 72.9 dBA in the evening. The winter season weekend noise level ranges from 37.2 to 65.8 dBA in the morning period, 40 to 71.3 dBA in the noon period and 40.5 to 69.7 dBA in the evening. The result showed that the level of winter season weekdays and weekend noise pollution in the noon is generally higher than morning and evening. The obtained data are compared with the limit values specified in the Environmental Hazard Assessment and Management Regulation. The hazardous noise level, which is considered as the threshold for causing physiological problems on humans, was determined to be exceeded at many locations. This situation may cause significant negative consequences on human health, quality of life and tourism sector. Obtained data were processed, and noise pollution levels for the city of Safranbolu were mapped using a geostatistical analysis software. In total, 16 noise pollution maps were drawn for different situations (e.g., weekdays, weekend, daytime, noon, night, summer season, winter season, etc.). Obtained noise level results demonstrate that the overall quality of the acoustic environment in our study area was medium level, which means that exposure to these levels over a long period can affect human health and quality of life. Finally, the results of a survey conducted as a part of this study were given, and possible measures and suggestions to reduce these noise levels in the district down to the desired limit values were discussed.

在本研究中，旨在确定并绘制萨夫兰博卢区中心的噪声污染水平，特别是机动车和/或行人交通繁忙的区域。在区中心选择了47个测量点进行噪声水平测量。在2017年夏季和2018年冬季的工作日和周末的上午（上午8点至10点）、午餐时间（中午12点至下午2点）和晚上（下午6点至晚上8点）进行测量。夏季工作日上午时段噪声水平范围为41.3至71.2分贝，中午时段为40至71.2分贝，晚上为40.6至73.1分贝。夏季周末上午时段噪声水平范围为45.3至69.1分贝，中午时段为44.7至71.4分贝，晚上为41.6至70.9分贝。结果表明，夏季工作日和周末上午、中午和晚上的噪声污染水平彼此接近。此外，冬季工作日上午时段噪声水平范围为32.3至68.5分贝，中午时段为30.8至73.3分贝，晚上为37.4至72.9分贝。冬季周末上午时段噪声水平范围为37.2至65.8分贝，中午时段为40至71.3分贝，晚上为40.5至69.7分贝。结果表明，冬季工作日和周末中午的噪声污染水平总体上高于上午和晚上。将获得的数据与《环境危害评估与管理条例》规定的限值进行比较。被认为是对人类造成生理问题阈值的有害噪声水平，在许多地点被确定为超标。这种情况可能会对人类健康、生活质量和旅游业造成重大负面影响。对获得的数据进行处理，并使用地理统计分析软件绘制了萨夫兰博卢市的噪声污染水平图。总共绘制了16张针对不同情况（如工作日、周末、白天、中午、晚上、夏季、冬季等）的噪声污染图。获得的噪声水平结果表明，我们研究区域的声学环境总体质量为中等水平，这意味着长期暴露在这些水平下会影响人类健康和生活质量。最后，给出了作为本研究一部分进行的一项调查的结果，并讨论了将该地区这些噪声水平降低到期望限值的可能措施和建议。
