Acoustic Study of an Auditorium by the Determination of Reverberation Time and Speech Transmission Index
The quality of the communication between teachers and students and ultimately, of classroom education itself, is closely linked to the acoustic quality of the auditorium. This acoustic quality can be characterized based on the reverberation time (RT), speech transmission index (STI) and the sound insulation. In this context, an acoustic study was conducted in an auditorium located in the Higher...
متن کاملMeasuring the Masses of Supermassive Black Holes
Supermassive black holes reside at the centers of most, if not all, massive galaxies: the difference between active and quiescent galaxies is due to differences in accretion rate relative to the Eddington rate and thus radiative efficiency. In this contribution, methods for measuring the masses of supermassive black holes are discussed, with emphasis on reverberation mapping which is most gener...
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...
متن کاملEvaluation of estimation models for acoustic reverberation time in educational and office environments
Noise pollution is considered as one of the most annoying factors in educational and office environments. In these environments where learning processes and intellectual activities are ongoing, an effective acoustic design is necessary. The aim of this paper is to assess the reverberation time as one of the important indicators in describing the acoustic characteristics of rooms. In this study,...
متن کاملPrediction of the Reverberation Time in Rectangular Rooms with Non- Uniformly Distributed Sound Absorption
SUMMARY The aim of this paper is first to review the best known reverberation time formulae and then to show that the reverberation time cannot be thereby predicted accurately in cases mostly encountered in practice, where the sound field is not diffuse. Introducing a correction to Fitzroy's formula allows better prediction of the reverberation time in the case of non-uniformly distributed soun...
