Contribution to creating better architectural and acoustic environments.
Development of numerical simulation methods for acoustic design inside and outside buildings, development of sound insulation systems for floor impact sound, modeling of acoustic materials and structures, noise propagation prediction.
In the field of architecture, it is important to consider the quality of space and quality of life (QOL) continuously. Our laboratory is engaged in environmental acoustics research, which is a field in architectural environmental engineering that is closely related to QOL. Our projects include the development of numerical simulation methods for acoustic design and noise control; prediction of a variety of sound fields; understanding and modeling acoustic characteristics of building members; and assessment of noise propagation. We have focused on developing highly efficient wave-based numerical simulation methods, because the spaces dealt with in the field of architectural acoustics are so large that computational costs for highly accurate wave-based numerical analyses are high. Recently, we have studied the development of sound insulation systems for floor impact sound, which can be a big problem in apartment buildings.
