Characterization, analysis, and noise control measures of a mechanical room

The acoustic environment of a mechanical room in buildings has received little attention because the space is occasionally occupied by building maintenance staff. However, the room typically includes the loudest noise sources in buildings. It is necessary to investigate noise exposure in the mechanical room for the staff. The aim of this study is, thus, to assess noise levels in the room by examining acoustic characteristics of the noise sources and mapping noise levels produced by the sources. This study also aims to provide optimal solutions to decrease the noise levels being produced. The framework consists of (1) identifying the major locations at which noise is being produced; (2) measurement of noise levels; and (3) performing noise level analysis of each activity. These findings will provide useful information to establish effective noise management plans for mechanical rooms in buildings.
