Abstract

Arsitek pembuat Auditorium Poltekesos Bandung mengatakan bahwa auditorium ini belum baik secara akustik dikarenakan menggunakan material standar. Oleh karena itu, dilakukan analisis kondisi kualitas akustik ruang dan evaluasi perbaikan auditorium dengan menetapkan beberapa kriteria desain. Untuk mencapai hal tersebut, dilakukan simulasi kondisi awal beserta perbaikannya Kondisi awal menunjukkan ruangan ini memiliki nilai RT overall sebesar 4.25s. Kemudian direct SPL yang tidak merata, %Alcons, STI, dan C50 yang tidak sesuai kriteria desain. Selanjutnya diusulkan perbaikan yang meliputi penggantian material dengan 2 variasi kemudian penambahan speaker dengan hasil rerata good dengan perolehan RT overall sebesar 1.2s untuk penggantian material variasi 1 dan 0.9s untuk variasi 2. Parameter objektif lain yaitu direct SPL belum merata untuk lantai 2, nilai %Alcons menjadi ideal dan good, nilai STI menjadi ideal dan good, C50 menjadi dominan di atas -5dB, dan C80 mengalami kenaikan hingga 10dB. Kemudian penambahan speaker berguna agar direct SPL merata untuk lantai 2 auditorium. Keempat variasi perbaikan membawa dampak positif. Kata Kunci: Auditorium, C50, C80, Direct SPL, RT, STI, %Alcons. =========================================================== The architect who made the Auditorium Poltekesos Bandung said that this auditorium was not acoustically good because it used standard materials. Therefore, an analysis of the quality condition of the room acoustics and an evaluation of the auditorium repair is carried out by determining several design criteria. To achieve this, a simulation of the early conditions and its improvements. The early condition shows that this room has an RT overall value of 4.25s. Then the direct SPL is uneven,% Alcons, STI, and C50 that do not match the design criteria. Furthermore, it is proposed that improvements include replacing the material with 2 variations, then adding speakers with a good average result with RT overall value of 1.2s for material replacement of variation 1 and 0.9s for variation 2. Other objective parameters are direct SPL not evenly distributed for the 2nd floor,% Alcons value. to be ideal and good, STI value to be ideal and good, C50 becomes dominant above -5dB, and C80 has an increase of up to 10dB. Then the addition of speakers is useful so that the direct SPL is evenly distributed to the second floor of the auditorium. all four variations of improvement have a positive impact. Keywords: Auditorium, C50, C80, Direct SPL, RT, STI, %Alcons.
