The Gereja “Kristus Tuhan Anugerah” in Surabaya faced several interior and acoustic challenges, including insufficient reverberation time and sound leakage into the surrounding residential area. To address these issues, the church underwent an interior redesign that incorporated acoustic simulations using I-Simpa software to develop effective solutions. Key improvements included the installation of absorbent materials to control reverberation time, the application of Sapphire insulation to prevent sound from leaking outside the church, and the installation of Beryl insulation in the Sunday school room to minimize external noise disturbances. As a result of these changes, the interior acoustic quality improved significantly, achieving optimal reverberation time for the worship space while also reducing the noise impact on the neighboring residential area. This project successfully created a comfortable worship environment, enhancing both the interior design and acoustics without disturbing the tranquility of the neighborhood.
