Evaluation of reverberation time of class room

Use of Artificial Intelligence in Room Acoustics Prediction Using a Photograph

“…These equations imply that RT60 increases as the size of the room increases and as the absorption of the room decreases 14 . The most accurate RT60 equation of those previously stated has been found to be the Sabine equation 1 . Due to the minimal parameters involved, it can also be the most time-efficient equation for RT60 calculation.…”

“…There are multiple equations for calculating RT60, including the Sabine (Eq. 2.1), Norris-Eyring, and Mellington-Sette equations 1 . These equations imply that RT60 increases as the size of the room increases and as the absorption of the room decreases 14 .…”

“…1 shows that within the test rooms, in comparison to the INM measurement for RT60 at 500 Hz the BIRM achieves an average accuracy of 84.33%, this is an accuracy within 0.113 seconds.…”

“…Current methods of determining acoustical parameters must adhere to current standards, require necessary training, include high equipment costs, and is time-consuming. The estimation of acoustics through calculation diminishes some issues with acoustics measurement but can be less accurate 1 . It can be difficult for individuals and businesses in the acoustics field to consider RT60 despite its importance as an influential acoustic parameter 2 which arguably cannot be assumed, especially within educational spaces 3,4 .…”
