Abstract
Studi ini bertujuan untuk menganalisis perilaku akustik dan mengoptimalkan penempatan pengeras suara di tiga ruang ibadah dengan volume yang berbeda: Kapel (941,2 m³), Gereja (312 m³), dan Aula (2.160 m³). Metode eksperimental kuantitatif digunakan, yang melibatkan pengukuran Tingkat Tekanan Suara (SPL) yang diambil dengan pengukur tingkat suara dalam kondisi kebisingan latar belakang dan selama pemutaran kebisingan merah muda. Pengujian mencakup tiga variasi penempatan (depan, tengah, dan belakang) dan tiga orientasi sudut proyeksi. Data dianalisis secara komparatif menggunakan perhitungan teoritis. Material penyerapan akustik dan isolasi ruangan yang lebih baik diperlukan untuk mempertahankan tingkat tekanan suara dalam kisaran ideal 70–80 dBA dan menjaga kebisingan latar belakang di bawah 55 dBA, sesuai dengan standar yang ditetapkan oleh Keputusan Menteri Negara Lingkungan Hidup No. 48 tahun 1996. Kata kunci: Akustik ruangan, Tingkat Tekanan Suara (SPL), Penempatan pengeras suara, Waktu reverberasi (RT60), Tempat ibadah, Fokus EASE, Hukum Kuadrat Terbali Kata kunci: Akustik ruangan, Tingkat Tekanan Suara (SPL), Penempatan pengeras suara, Waktu reverberasi (RT60), Tempat ibadah, EASE Focus, Hukum Kuadrat Terbalik / This study aims to analyze acoustic behavior and optimize loudspeaker placement in three worship spaces of varying volumes: the Chapel (941.2 m³), the Church (312 m³), and the Hall (2,160 m³). A quantitative experimental method was employed, involving Sound Pressure Level (SPL) measurements taken with a sound level meter under background noise conditions and during pink noise playback. Testing covered three placement variations (front, middle, and rear) and three projection angle orientations. Data were analyzed comparatively using theoretical calculations acoustic absorption materials and improved room insulation are necessary to maintain sound pressure levels within the ideal 70–80 dBA range and keep background noise below 55 dBA, in accordance with the standards set by the State Minister for the Environment Decree. 48 of 1996. Keywords: Room acoustics, Sound Pressure Level (SPL), Loudspeaker placement, Reverberation time (RT60), Place of worship, EASE Focus, Inverse Square Law Keywords: Room acoustics, Sound Pressure Level (SPL), Loudspeaker placement, Reverberation time (RT60), Place of worship, EASE Focus, Inverse-Square Law.
