Abstract
Standar akustik dalam sebuah auditorium dapat berdampak pada kenyamanan dan tujuan setiap acara yang dilaksanakan. Dalam upaya pemenuhan standar sebuah auditorium serbaguna penelitian ini bertujuan untuk mengetahui distribusi nilai parameter akustik di dalam gedung khususnya pada bagian penonton di lantai satu. Parameter yang di evaluasi meliputi persebaran tingkat tekanan bunyi, persebaran waktu dengung, persebaran tingkat kejelasan suara vokal dan suara musik, serta persebaran perbandingan sinyal antara telinga kanan dan telinga kiri. Dalam penelitian tugas akhir ini, pengujian dilakukan di GSN ITS. Pengukuran dilakukan pada lantai satu sebagai representasi dari posisi penonton yang duduk dibagian paling depan, tengah, belakang, paling dekat dengan tembok, dan audiens yang berada di tengah ruangan. Dari hasil pengukuran dan analisa didapat bahwa gedung GSN memiliki nilai NC 44.8 – 51.2. Sementara nilai waktu dengung tertinggi pada bagian tengah gedung yaitu 2.73 detik, nilai C80 adalah -4.23 dB hingga 3.30 dB, nilai D50 sebesar 48.95-52.03% dan nilai IACC berkisar antara 0.95-0.98. Berdasarkan nilai tersebut maka gedung GSN belum memenuhi standar nilai yang direkomendasikan dan perlu dilakukan perbaikan.

An acoustic standard in an auditorium can impact on the convenience and purpose of each event. In an effort to fulfill the standard of a multifunctional auditorium this study aims to find out the distribution of acoustic parameter values in the building, especially on the part of the audience on the first floor. The evaluation parameters include the spread of sound pressure level, the dispersion of the reverberation time, the distribution of the vocal sound clarity and the sound of music, and the spread of the signal ratio between the right ear and the left ear. In this thesis research, testing is done in GSN ITS. Measurements are made on the first floor as a representation of the viewer's position that sits at the front, center, back, closest to the wall, and the audience in the center of the room. From result of measurement and analysis got that GSN building have value of NC 44.8 - 51.2. While the highest buzzing time in the center of the building is 2.73 seconds, the value of C80 is -4.23 dB to 3.30 dB, the D50 value of 48.95-52.03% and the IACC value ranges from 0.95-0.98. Based on these values, the GSN building has not met the recommended value standard.
