Abstract

A questionnaire survey was conducted for the clarification of the current state of satisfaction on sound insulation performance in the multistorey dwellings for sale and for rent. The result suggested that the situation was the same with the study completed in 1970s: the floor impact sound insulation performance was one of the most unsatisfied attributes. In addition, tendency of the room type (i.e. 1K or 3LDK), family structures (i.e. single or with kids) and architectural specification (i.e. structure types of the building) on the multistorey dwelling for sale and for rent was different.
