【 摘 要 】
There are various worship activities held at mosque, such as reciting, prayers and Friday sermon and acoustically, it is categorized as speech. Syamsul Ulum Mosque (MSU) located at Telkom University, Indonesia was taken as an object for research since there were no information nor historical data about actual acoustic condition and acoustical design. Main hall, considered as primary venue, is taken as analysis area. Measurement covers only speech-related objective parameters; reverberation time (RT), Definition (D50), Sound Strength (G) and Noise Criteria (NC). Furthermore, identification of proper area-for-speech activity and uniformity of distribution energy of impulse response parameters is illustrated by map contour. Since there is some value at certain areas does not have value within recommendation range, the main hall of MSU is inappropriate venue to accommodate worship activities.
