• Resumen

  • Church, a worship space for Christian, which is used as a room not only for speech, but also for music performance, is categorized as a multipurpose room that has to fulfil some specified conditions based on its function. GKI Taman Cibunut was chosen as the object of this research. Acoustics conditions of a worship space can be illustrated by acoustic parameters, such as SPL distribution, reverberation time (RT and EDT), clarity for music (C80), clarity for speech (D50), and RASTI. Acoustics condition for a room can be determined by several ways. One of them is by sound field measurement using binaural room impulse response (BRIR). This method is used by means of recording the impulse response of the room. By modelling and simulation, acoustics condition of the room can also be determined. In this research, the room used is GKI Taman Cibunut. The results of measurements show that in empty condition GKI Taman Cibunut has EDT value between 1.4 and 1.8 second. This value meets the optimum reverberation for multipurpose room. C80 value meets standard criteria, while D50 value in some point is below standard criteria. SPL distribution, C80, D50, RASTI at GKI Taman Cibunut can be reformed by applying diffuser and relocated loudspeaker position.
