Measurements in room acoustics Open
Regardless of the field, measurements are essential for validating theories and making well-founded decisions. A criterion for the validity and comparability of measured values is their uncertainty. Still, in room acoustical measurements, …

Measurement Uncertainty of the Room Acoustic Clarity Index Open
Measured room impulse responses are inherently uncertain like all measured quantities. This input uncertainty naturally propagates to derived metrics such as room acoustic single number quantities. Based on the framework provided by the Gu…

3D modelling photogrammetry to support acoustic measurements and derive geometries for simulation Open
The accuracy of acoustic measurement locations usually demands a correct geometrical description of the studied auditorium. Likewise, for numeric simulations the geometry of the modelled room needs to be available in appropriate detail. Re…

Experimental investigations on sound energy propagation in acoustically coupled volumes using a high-spatial resolution scanning system Open
The aim of this work is to study the sound field distribution in an experimental scale-model of two coupled rooms. An automatic scanning mechanism moves a microphone in small grid steps to measure room impulse responses at each grid point.…

Visualisation of the sound field in a concert hall Open
The associated dataset shows the visualisation of the measured sound field in a concert hall. Using the setup described by Witew et al. [https://doi.org/10.1121/1.4978022] impulse responses were automatically sampled over a surface of 5.3 …

Sampling the sound field in auditoria using large natural-scale array measurements Open
Suitable data for spatial wave field analyses in concert halls need to satisfy the sampling theorem and hence requires densely spaced measurement positions over extended regions. The described measurement apparatus is capable of automatica…

Animation of measured room impulse responses in an auditorium with and without chairs Open
Acoustical measurements in concert halls are crucial for experimental investigations, however, can be laborious endeavors. Automated measurement systems can reduce the efforts and can provide array data with relations between measurement p…
