Room and Building Acoustics

Updated: 19-09-2015

Computational methods
Besides urban acoustic applications, the PSTD method os used to detailedly study architectural acoustic problems, such as sports halls (paper J18).In 2015, a PhD project was started on numerical modelling of transient sound propagation in buildings. In this project, we aim to develop a time-efficient wave-based model to study structural vibrations in buildings.sportshall

Sportshall, for which prediction models have been tested.

Lightweight structures
Building with lighweight materials is beneficial for economic reasons. However, lightweight building structures lead to various acoustic problems, especially in the low frequency range. In 2015, a PhD research has started in this field titled: Impact noise insulation of lightweight floor systems at low frequencies.Lightweight_system
Measurement expeditions
As a student at the Eindhoven University of Technology, I have co-organized two building physics measurement expeditions. In both expeditions, measurements were conducted in odd locations where extreme measurement conditions prevailed: the Ice hotel in Jukkasjärvi, Sweden) and the historical outdoor parliament site of Thingvellir on Iceland. In the icehotel, the sound insulation between hotel rooms and the room acoustics properties of the ice chapel were measured (paper N2). The parliament site on Iceland is not currently in use, yet its function as ancient parliament site was partly motivated by its acoustical properties. The measurements revealed whether this was the case (paper N3).In 2015, students from our group carried out extensive measurements in the ancient theatres in Greece.
