A QUESTIONNAIRE SURVEY ABOUT SOUND INSULATION OF WALLS AND FLOORS IN WOODEN APARTMENT BUILDINGS, INQUIRING OF RESEARCHERS AND ENGINEERS

Abstract

We executed an questionnaire survey inquiring about engineering level on sound insulation of walls and floors of wooden apartment buildings recently built in Japan. (This questionnaire, however, was practically executed in 1994.) Answerers were Japanese researchers and engineers whose specialty was sound insulation of buildings. In this paper, we introduce the results of this questionnaire and give our opinion about sound insulation performance of walls and floors of wooden apartment buildings.
