The test was based on six acoustic scenes highlighting specific acoustic phenomena and for three complex, "real-world" spatial environments. The results demonstrate that most present simulation algorithms generate obvious model errors once the assumptions of geometrical acoustics are no longer met. As a consequence, they are neither able to provide a reliable pattern of early reflections nor do they provide a reliable prediction of room acoustic parameters outside a medium frequency range. In the perceptual domain, the algorithms under test could generate mostly plausible but not authentic auralizations, i.e., the difference between simulated and measured impulse responses of the same scene was always clearly audible. Most relevant for this perceptual difference are deviations in tone color and source position between measurement and simulation, which to a large extent can be traced back to the simplified use of random incidence absorption and scattering coefficients and shortcomings in the simulation of early reflections due to the missing or insufficient modeling of diffraction.}, language = {en} } @article{WeinzierlLepaAckermann2018, author = {Weinzierl, Stefan and Lepa, Steffen and Ackermann, David}, title = {A measuring instrument for the auditory perception of rooms: The Room Acoustical Quality Inventory (RAQI)}, series = {The Journal of the Acoustical Society of America}, volume = {144}, journal = {The Journal of the Acoustical Society of America}, number = {3}, publisher = {Acoustical Society of America}, issn = {0001-4966}, doi = {10.1121/1.5051453}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-58954}, pages = {1245 -- 1257}, year = {2018}, abstract = {With the Room Acoustical Quality Inventory (RAQI), a measuring instrument for the perceptual space of performance venues for music and speech has been developed. First, a focus group with room acoustical experts determined relevant aspects of room acoustical impression in the form of a comprehensive list of 50 uni- and bipolar items in different categories. Then, n = 190 subjects rated their acoustical impression of 35 binaurally simulated rooms from 2 listening positions, with symphonic orchestra, solo trumpet, and dramatic speech as audio content. Subsequent explorative and confirmative factor analyses of the questionnaire data resulted in three possible solutions with four, six, and nine factors of room acoustical impression. The factor solutions, as well as the related RAQI items, were tested in terms of reliability, validity, and several types of measurement invariance, and were cross-validated by a follow-up experiment with a subsample of 46\% of the original participants, which provided re-test reliabilities and stability coefficients for all RAQI constructs. The resulting psychometrically evaluated measurement instrument can be used for room quality assessment, acoustical planning, and the further development of room acoustical parameters in order to predict primary acoustical qualities of venues for music and speech.}, language = {en} } @misc{AckermannIlseGrigorievetal.2018, author = {Ackermann, David and Ilse, Michael and Grigoriev, Dmitry and Lepa, Steffen and Pelzer, S{\"o}nke and Vorl{\"a}nder, Michael and Weinzierl, Stefan}, title = {A Ground Truth on Room Acoustical Analysis and Perception (GRAP)}, publisher = {TU Berlin}, address = {Berlin}, doi = {10.14279/depositonce-7003.4}, year = {2018}, abstract = {A database of 35 virtual room models was created that can serve as a ground truth for the future development of room acoustical parameters beyond ISO 3382-1.
