Renew the acoustics of the classroom by default

The design of acoustics in the classroom relates to standards that provide clarity of speech for the student and acoustic comfort for the teacher. This research aims to improve the acoustics of a virtual classroom situation through three parameters: RT60 reverberation time, STI, and sound purity C50, and linking them to classroom-related acoustic quality standards. The classroom is located in a middle school characterized by its prefabricated building in Baghdad. In this study, audio simulation was used through the Odeon application. The simulation was carried out in two stages. The first stage is an audio simulation of the reality of the classroom, and the second stage is after proposing a solution The simulation results for the proposed solution showed that it conforms to the international standards represented by the French standard for educational buildings for RT60, the ISO_9921-2003 standard for the STI value, and the Din-18041-2004 standard for the C50 parameter, thus an effective sound improvement was achieved
