The same reverberation time in two identical rooms does not necessarily mean the same levels of speech clarity and sound levels when we look at impact of different ceiling and wall absorbers

چکیده
It is common to only use Reverberation Time (RT) for setting the acoustic conditions in a classroom for teaching and learning activities. To calculate the RT in rooms with ceiling absorption is common but this data can also be misleading. Indeed, we measured the same RT values in two identical rooms with different acoustic treatment, even though the calculations predicted significant differences and interestingly the rooms are also be perceive quite differently in reality.

Incontrovertibly, the sense of hearing is one of the five most substantial human senses. In fact, the human ear receives sound and transmits to the human brain by the auditory organs. Hence, sound can be considered as one of the key tools of human communication with each other and the environment around them. Since acoustic has a profound impact on the body, soul, and the performance of human ...

Noise pollution is considered as one of the most annoying factors in educational and office environments. In these environments where learning processes and intellectual activities are ongoing, an effective acoustic design is necessary. The aim of this paper is to assess the reverberation time as one of the important indicators in describing the acoustic characteristics of rooms. In this study,...
