Abstract

This study was conducted to examine the difference between the value of the reverberation time gain by calculation using theoretical method and measurements in real room. The study involved a lecturer room in University Tun Hussain Onn Malaysia (UTHM). The theoretical methods used were Sabine, Eyring and Millington-Sette. Measurement in the actual room used a method that had been stated in ISO 3382, interrupted noise method. The room setting was divided into 3 conditions that were empty room, room with curtains and room using egg containers as sound absorbers. Calculation method was based on the three room conditions. Measurement and calculation results of reverberation time were analyzed with the method of mean absolute error (MAE). The analysis was done based on the formulas used, and based on the variables. The results showed that Sabine formula produces the closest reverberation time value with the actual measurement.
