How much sound does a vegetated roof absorb? To answer that question an appropriate measurement method is needed. In our recently published Applied Acoustics paper by Chang Liu, Fotis Georgiou and Maarten Hornikx, the acoustic impedances of greens roofs were retrieved by fitting parameters of a surface impedance model by measurents on the roofs. It…
At July 1st, both Yi Qin and Indra Sihar will defend their PhD theses. applicable to other types of lightweight floors. Indra Sihar present his work titled: Numerical modelling of transient low-frequency sound propagation and vibration in buildings. His defense starts at 11AM sharp and can be attended online via this Teams link, or at…
Xueying Guan joined the Building Acoustics group as a PhD student on April 1st, 2022. Her PhD study will contribute to the research line on the development of sound-absorbing materials, focused on the acoustic material design by 3D printing of natural fiber composites. She will explore multifunctional possibilities and optimization of 3D-printed sound absorbers for…
Reliable data on acoustical properties of materials are crucial for the design of a desired acoustic environment as well as to obtain accurate results from acoustic simulations. Although the acoustical properties of materials can be obtained via laboratory measurements, situations where in situ measurements are needed are often encountered. In our recent paper published in…
As of September 1st, Bram Botterman joined our group as a guest researcher. Bram graduated master with us some years ago and he carried out nice research on sound absorbing materials at that time (4TU sound absorbing glasses project, journal publication on sound absorbing materials). While leading his company Matude currently, he decided to come…
Find out about our latest Acta Acustica paper! We experimentally explored the use of a heel drop as an impact source to quantify the impact sound performance of lightweight wooden floors. A impact force plate was used for this purpose. At low frequencies, the measurement quality using the help drop is higher compared to an…
Dr. Jieun Yang (in the picture above) was appointed to be assistant professor in acoustic materials. She is currently working as a postdoc in our group. Her appointment starts as of January 1st, 2021.
Chang Liu has been awarded a Young Professionals Grant for the Inter-Noise conference in Hamburg (August 2016), where she will present the paper titled 'Impedance deduction for vegetated roof surfaces: multiple geometry strategy'. The grant is issued by the International Institute of Noise Control Engineering (I-INCE). This is the second conference award in a row for…
At september 1, Yi Qin (picture) has started his PhD research in our Building Acoustics chair, titled: Impact noise insulation of lightweight floor systems at low frequencies. The research will be carried out in collaboration with Level Acoustics and Rijbroek vloeren
