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...

An important challenge for acoustic engineers in room acoustics design is related to the performance of multi-purpose auditoriums, which are typically designed suit several requirements. With this intent, analysis scenarios usually performed individually, and then an acceptable solution, that may be adapted situations, selected. One way providing a more appropriate each function auditorium usin...

The use of loudspeaker arrays to create a spatial impression within an auditorium requires the exact knowledge of the synthesized wave eld. The interaction between loudspeaker array and the enclosure can be investigated by numerical simulation. A new method for the computation of dynamical 3D sound elds is applied to obtain the impulse response from a loudspeaker array to the listening positions.
