Abstract
Sebuah lapangan basket harus memiliki parameter akustik yang baik agar audience bisa menikmati pertandingannya. Parameter akustik meliputi Noise Criteria(NC), persebaran Sound Pressure Level (SPL), Waktu Dengung, nilai kejelasan speech(D50) dan nilai kejelasan suara musik(C80). Pengukuran dilakukan pada tempat duduk penonton yang berada pada tribun serta sekitar lapangan. Dari hasil pengukuran dan analisa didapat bahwa lapangan basket DBL Arena memiliki nilai NC 52-69 yang seharusnya hanya berkisar 45-55.Nilai NC yang belum sesuai ini terjadi karena banyaknya suara dari luar gedung yang masuk ke dalam lapangan. Nilai persebaran SPLnya belum merata dengan selisih SPL titik terjauh dengan titik terdekat sebesar 15 dBA untuk speaker posisi 1 dan 10 dBA untuk speaker posisi 2. SPL yang belum merata dikarenakan ruangan besar dan juga adanya standing wave. Sementara nilai waktu dengung berkisar antara 2.2 s- 2.4 s, yang seharusnya ≤ 1.8 S. Nilai waktu dengung besar dikarenakan volume ruangan yang besar serta ruangan yang bergema. Nilai Standar C80 yang dicapai 50% dari Total 46 Titik pengukuran . Nilai Standar D50 hanya dicapai 41% dari Total 46 Titik pengukuran. Berdasarkan hasil parameter akustik ruang yang telah diukur, maka Tempat Duduk Penonton Lapangan Basket DBL Arena belum memenuhi standar akustik yang direkomendasikan dan perlu dilakukan perbaikan.

A basketball court must have good acoustic parameters for the audience to enjoy the game. Acoustic parameters include Noise Criteria (NC), Distribution of Sound Pressure Level (SPL), Reverberation Time, speech clarity value (D50) and musical clarity value (C80). Measurements are made on the seats of spectators in the stands as well as around the field. From the results of the measurement and analysis found that the DBL Arena basketball field has a value of NC 55-65 which should only range from 45-55. NC values that have not good enough because of the large number of noise from outside of the building get into the field. The SPL spread value is not evenly distributed well by SPL difference of farthest point with the closest point are 15 dBA for 1st Speaker Position and 10dBA for 2nd Speaker Positions. SPL is not evenly distributed well due to large room and standing wave. While the value of the reverberation time ranges is from 2.2 s- 2.4 s, it should be ≤ 1.8 S. The large value of reverberation time is due to the large volume of the room and the echoing room. C80 Standard Value achieved 50% of Total 46 Point measurement. The D50 Standard value is only achieved 41% of the Total 46 Point measurements. Based on the measured acoustic parameters of the space, the DBL Arena Basketball Seating Audience does not meet the recommended acoustic standards and needs to be improved.
