Comparing Attention and Cognitive Function in School Children across Noise Conditions: A Quasi-Experimental Study.

Objective: The effect of acute noise on cognitive function has long been a topic of study, yet these effects remain a serious problem for learning performance in school children.

Methods: From November 15, 2010 to December 8, 2010, we enrolled 268 students from three elementary schools (135 boys and 133 girls, 10-12 years old) in Ulsan, Korea. The study subjects were divided into two groups according to their test conditions (background versus additional noise), and tests were conducted using psychological examination tools.

Influence of Transportation Noise and Noise Sensitivity on Annoyance: A Cross-Sectional Study in South Korea.

Environmental noise is known to cause noise annoyance. Since noise annoyance is a subjective indicator, other mediators-such as noise sensitivity-may influence its perception. However, few studies have thus far been conducted on noise annoyance in South Korea that consider noise sensitivity and noise level simultaneously.
