Abstract

The operation of computer program for acoustic simulation is an alternative for acoustic analysis method which is fund, time, and energy saving. ECOTECT v.5.20 is one of the computational building performance simulation integrated program with fully 3D, that is able to simulate and analyze acoustic performance of an auditorium. Accordingly it can be used as a program to design the position and area of absorption surface. With consideration to simulation activities, a computer program that makes a model of a real environment always faces the problem of simplifying a model. This problem definitely will affect the precision between the field assessment result and the parameter simulation result of a room acoustic impulse response. Verification of simulation result on the field assessment result has to be done in order to show the computer program validation to be used as a simulation tool for the next research. The simulation result shows that the Reverberation Time (RT) computation is the most equal to the field measurement result with

Abstract

A performance can either be enjoyed or not depending on the acoustic system of the room. The quality of the acoustic system can be measured based on an objective parameter that includes background noise, sound pressure level distribution and reveberation time. The measuring result in a case study shows that an auditorium that has problems relating to background noise level has to consider its ventilation system to avoid high background noise levels. It is important to consider the position of outdoor condensers, ducting joints and openings because the resulted low sound frequency can truly be disturbing during performances, especially to the audiences. Observations drawn on the acoustical performance show that some factors in interior design have to be considered such as room shape and dimension, finishing material and its arrangement in interior elements, to avoid uneven sound distribution and reveberation time that exceeding the standard criteria multifungsional auditoriums. Abstract in Bahasa Indonesia : Suatu pertunjukan dapat dinikmati dengan nyaman atau sebaliknya, sangat tergantung pada kualitas akustik ruang. Kinerja akustik ruang auditorium dapat dinilai berdasarkan parameter objektif yang meliputi bising latar belakang (background noise), distribusi tingkat tekanan bunyi dan respon impuls ruang terutama waktu dengung (reverberation time). Hasil pengukuran terhadap sebuah studi kasus menunjukkan bahwa auditorium yang mempunyai masalah pada tingkat bising latar belakang (background noise level) perlu memperhatikan desain ventilasi untuk menghindari tingkat gangguan bising yang berlebihan. Perhatian juga harus ditujukan pada peletakan outdoor (condensing) AC, sambungan ducting, dan bukaan, karena bunyi frekuensi rendah yang dihasilkan sangat mengganggu selama kegiatan berlangsung, utamanya bagi area penonton. Selanjutnya, untuk menghindari distribusi suara yang tidak merata dan waktu dengung (reverberation time) yang melebihi kriteria yang disyaratkan bagi auditorium multifungsi, maka analisis kinerja akustik menunjukkan beberapa faktor interior yang perlu mendapat perhatian seperti bentuk dan dimensi ruang, serta bahan finishing dan desain peletakannya pada elemen interior. Kata kunci: parameter akustik ruang, tingkat bising latar belakang, distribusi tingkat tekanan bunyi, waktu dengung.
