Subjective Evaluation of Auralization of Physics-based Room Acoustics Modeling
This paper describes the results of subjective evaluation of auralization by listening tests. The task was to compare real-head recorded and auralized sound samples. The evaluation process as well as the creation of soundtracks are briefly reviewed. The listening test procedure is presented along with the analyzed results of a case study. They show that with a simple room geometry (a lecture ro...
متن کاملPredicting reverberation times in a simulated classroom.
By varying the sound-absorption treatments in a simulated classroom, experimental results were compared with analytical and computer predictions of reverberation time. Analytical predictions were made with different absorption exponents, which are the result of different weighting procedures involving room surface areas and the sound-absorption coefficients. Sound scattering was found to influe...
متن کاملA Screening Approach for Classroom Acoustics Using Web-Based Listening Tests and Subjective Ratings
BACKGROUND Perception of speech is crucial in school where speech is the main mode of communication. The aim of the study was to evaluate whether a web based approach including listening tests and questionnaires could be used as a screening tool for poor classroom acoustics. The prime focus was the relation between pupils' comprehension of speech, the classroom acoustics and their description o...
متن کاملInvestigating the performance of machine learning-based methods in classroom reverberation time estimation using neural networks (Research Article)
Classrooms, as one of the most important educational environments, play a major role in the learning and academic progress of students. reverberation time, as one of the most important acoustic parameters inside rooms, has a significant effect on sound quality. The inefficiency of classical formulas such as Sabin, caused this article to examine the use of machine learning methods as an alternat...
