​Building multi-storey wooden apartments has become more popular in recent years. These buildings provide many advantages regarding environment, industrialization and cost.  However problems regarding sound and vibration disturbances in these buildings have remained unsolved. Low frequency impact noise caused by footsteps on wooden floors is a main source of annoyance for the residents despite fulfilling the requirements in building codes.

AkuLite is a research project involving Swedish building industry and acoustic research groups which aims to develop sound and vibration criteria which are consistent with people's perception in lightweight buildings. This project consists of 7 work-packages investigating different aspects of low-frequency noise disturbances in these buildings. One of the main outcomes of the project which is covered in work-package 2 is discovering correlation of transmitted impact noise with impact source characteristics and dynamic behavior of lightweight floors.


The project is carried out at the Division of Applied Acoustics.

Keywords: Wooden buildings, Lightweight floors, low-frequency footstep noise
