The random-incidence absorption coefficient is measured in a reverberation room as per ISO354:2003 (2003), assuming a diffuse and isotropic sound field. However, reproducibility issues across different laboratories suggest that the assumption of isotropy does not hold in practice. This dissertation presents a novel experimental method for capturing and analyzing the directional characteristics of energy decay […]

As the awareness of health effects caused by noise has grown in recent years, so has the importance of studying noise in educational buildings. This dissertation focuses specifically on the impact of noise on young children in educational buildings from a children's perspective, a topic that has not been extensively explored. Previous research indicated that […]
