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 Institute of Technological Studies (ISET) of Sfax, south of Tunisia. The investigation used acoustic measurement methods to assess the acoustic quality of the nave and the results were compared with the standards ISO 3382-1 and ISO 3382-2.The results of this work were obtained by measuring the RT values and the sound insulation of auditorium façades. In addition to these parameters obtained by measurements, STI was obtained through the computer simulation (utilizing ODEON ver. 4.2, assuming the occupied case). The results showed that the measured and calculated values were consistent with those proposed by the standards for speech auditoria (RT_500Hz = 0.98 s, D₅₀> 50% and STI> 0.45), and are in line with the speech intelligibility requirements.

The aim of evaluating and studying the creative city indicators of the city of Qazvin is to determine the creativity trend of this city during the past years and to recognize the dominant field of creativity for this city. Therefore, this study has tried to analyze the creative city indicators about the city of Qazvin by using “descriptive-analysis” method as well as applying secondary data, TOPSIS model, AHP model and SPSS software. First, 13 indicators have been collected to determine the creativity trend from2009 to 2015, then the current trend of creativity in recent years has been obtained using quantitative models. Regardless of the year 2009 and the years before that, the best rank belongs to 2013 with 0.3228 scores. Generally, the creativity trend has decreased with a gentle slope in recent years. In the following sections, within introducing the dominant field of creativity among the five investigated fields, this conclusion has been made that the city of Qazvin has potentials to move toward a creative city.
