Abstract
For a house to maintain the standards of a quiet residential environment, it is necessary to reduce not only inter-floor noise delivered from neighboring houses but internal noise sources as well. Currently, noise measures on facility and equipment have been established in apartment houses in South Korea. This study aimed to provide foundational data needed to provide institutional standards on facility noise in apartments. Thus, this study analyzed noise level and acoustical parameters (loudness, sharpness, and roughness) with regard to noises from hoods and boilers in kitchens. This study also studied an annoyance rating, which was a subjective response to the noise, using 36 subjects. It also quantified a subjective response by calculating a %HA (percentage of highly annoyed) according to the maximum noise level from a boiler and kitchen hood, and a mean value of annoyance. No significant difference between the two rating scales was found.
