Abstract

The article presents the parameters of the acoustic insulation capacity of a traditional wooden ceiling before and after renovation in a historical building from the beginning of the 20th century. Due to a change in the use of the building, the existing wooden ceilings were reinforced with two symmetrical C-bars with the use of Cofrastra 40 composite steel-concrete slab. The composite slab, being the ceiling support, made it easy to mount a suspended ceiling with thermal and acoustic insulation layers specifically selected for the building’s needs.

Summary

Introduction

Wooden ceilings in residential and public buildings were commonly used until the beginning of the 20th century. A wooden ceiling without any insulation layers can be called a „bare” ceiling. This kind of ceiling is characterized by poor acoustic insulation capacity. During modernization of old buildings with wooden ceilings, construction partition should be properly designed to comply with legal requirements. The article describes and calculates the parameters of sound insulation capacity for four wooden ceiling options. The sound transmitted through a building partition results from stimulating the partition to vibrate by an acoustic wave falling on it. The acoustic insulation capacity of a partition is its ability to suppress the sound penetrating through it. The partition will have adequate acoustic insulation capacity when sounds coming from the other side will be incomprehensible and they will not disturb the users of the other rooms. Impact sounds can be caused by walking on the other side of the ceiling or by moving or rolling objects
