The journal aims to advance public health science and practice through the publication of quality research. The main focus of this journal covers various aspects of public health such as epidemiology, biostatistics, population health, health promotion, environmental health, occupational health and safety, health policy administration, public health nutrition, hospital management, maternal and child health, and reproductive health and management of infectious and non-communicable diseases.</p> en-US [email protected] (Slamet Wardoyo) [email protected] (Suprijandani) Mon, 13 Oct 2025 08:45:33 +0000 OJS 3.3.0.19 http://blogs.law.harvard.edu/tech/rss 60 https://phrdevelopment.com/index.php/phrd/article/view/34 <p>Noise in classrooms can disrupt communication between teachers and students, potentially affecting learning outcomes. Previous research indicates that noise exceeding environmental health standards may contribute to communication difficulties during lessons. This study aimed to analyze the effect of classroom noise and communication disruptions on students’ learning achievement. An observational analytic study with a cross-sectional design was conducted among 4^th and 6^th grade students at one of the elementary schools in South Surabaya. Noise levels were measured in the classrooms, and students were assessed for communication disruptions and learning achievement. Logistic regression was used for data analysis. All classrooms exceeded the environmental health noise threshold of 55 dB(A), with an average level of 67.45 dB(A). Noise was significantly associated with communication disruptions (OR = 5.118; p = 0.012). Classroom noise increased the risk of communication disruptions but did not directly affect students’ learning achievement. It is recommended to install soundproof partitions and double-glazed windows to reduce noise. Future studies should investigate the interaction between teaching methods and student achievement.</p> Nur Maulidah Dina Rahmani, Rachmaniyah, Irwan Sulistio, Khambali, Sherawali Copyright (c) 2025 Nur Maulidah Dina Rahmani, Rachmaniyah, Irwan Sulistio, Khambali, Sherawali https://creativecommons.org/licenses/by/4.0 https://phrdevelopment.com/index.php/phrd/article/view/34 Fri, 24 Oct 2025 00:00:00 +0000
