Measurement And Evaluation Of The Reverberation Time For Classrooms In UTEM
Reverberation time is important in achieving the standard speech intelligibility during lectures in UTeM’s classroom. Basically, RT60 means the time for a sound to decay 60 dB. The decaying of sound will be affected by the materials used in the classroom, the noise level background and the size of t...

| Summary: | Reverberation time is important in achieving the standard speech intelligibility during lectures in UTeM’s classroom. Basically, RT60 means the time for a sound to decay 60 dB. The decaying of sound will be affected by the materials used in the classroom, the noise level background and the size of the classroom itself. The reverberation time must not exceed the ANSI S12.60-2002 standard which is 0.6 or 0.7 second depending on the classroom sizes. In order to achieve this standard, calculation and measurement need to be done on a selection of UTeM’s classroom and will be compared to the standard. The measurements will based on the ASTM E336-97 testing standard in order to get accurate results. As a conclusion to this project, the reverberation time for UTeM’s classroom does not achieve the ANSI S12.60-2002 standard. |
