Different methodologies used to evaluate acoustic performancein in
educational lecture hall. Theses technical methods have been used in order to define the
acoustic problems in lecture hall and suggest acoustic and architecture treatments to solve
these acoustic problems. The methods that used for acoustic analysis were Sabin, Eyring,
Arau-puchades and ODEON. This paper is foucing on acoustic performance in lecture
hall 2 in Tanta Engineering. Acoustic study has been done for lecture hall as follows:
Evaluation the acoustic performance by field measurements for reverberation time,
manual calculation and acoustic simulation; ODEON software. Different acoustic
performance analysis was performed. Different acoustic and architecture treatments were
suggested based on the analysis. The final results of room acoustics of different cases
carried on the hall were compered to the international requirements for educational
spaces. The main problems based on the acoustic analysis are the increase of hall height,
architecture design of ceiling and hard covering of the internal surfaces
