متن کاملAcoustic quality assessment at Nezamol molk dome of Jame mosque of Isfahan
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 ...
