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
