An image-based method for non-contact and dynamic room acoustics analysis

The proposed method as a measurement and monitoring instrument was accurate enough to be used for acoustic analysis of buildings and can be considered as an alternative for the classical method. This method requires less time to be performed and provides more accurate calculations, thus, it can be used to make the right decision regarding the building acoustic condition; moreover, as it is a non-contact analysis method, it can significantly protect evaluator person against the risk of accidents caused by industrial machinery.
