The article presents the results of field measurements of apparent sound insulation between office rooms separated by a lightweight skeleton wall with plasterboard cladding and mineral wool filling. The tests were carried out in the same office rooms, but the connection method of the wall with the façade post was changed. Thanks to this, the impact of the connection method of the wall with the post on sound insulation between the rooms was determined. In addition, the measurements were repeated for the "best" connection variant, but only after the completion of the finishing stage of the rooms. The finishing works consisted in the construction of raised floor and suspended ceiling, laying floor covering and furnishing. Additional service ducts between the rooms were also made during this stage. The effect of these works had a significant impact on the reduction of sound insulation. The article presents potential causes of this phenomenon.
