5. what is the recommended reverberation time value in a room, that's ensure proper speech intelligibility ?

6. what is the impact of noise on the learning process ?

"Excessive noise in schools has a negative impact on student learning and performance" Haines, Stansfeld, Job, Berglund, & Head, 2001)
