Abstract
Lalu lintas merupakan sumber kebisingan yang mendominasi di perkotaan serta memberikan dampak buruk terhadap produktivitas dan kesehatan penduduk. Upaya pengendalian kebisingan lalu menemui beberapa kendala, di antaranya amplitudonya fluktuatif, komposisinya beragam, dan mencakup wilayah yang luas. Penelitian ini bertujuan untuk mendapatkan sistem pengendalian kebisingan lalu lintas dengan metode active noise control, passive noise control, gabungan metode active noise control dan passive noise control, serta menyusun rencana penerapan metode active noise control dan passive noise control sebagai pengendali kebisingan lalu lintas dalam kerangka kerja soundscape. Sinyal kebisingan lalu lintas diperoleh melalui pengukuran dan field recording di lima lokasi dan empat zona waktu di Jalan Soekarno-Hatta Surabaya. Analisis karakteristik sinyal kebisingan lalu lintas dilakukan dengan pendekatan soundscape berdasarkan pola spektral, pola temporal, dan pola spasial. Konfigurasi active noise control yang terdiri dari sistem active noise cancellation menggunakan algoritma FxLMS mampu mereduksi bunyi sebesar 15,6 dB dan noise masking mampu menutupi kebisingan dengan efek threshold shift. Sementara itu, konfigurasi passive noise control yang berbentuk sonic crystal window menunjukan performa IL sebesar 20 dB pada frekuensi 500 Hz dan 1.250 Hz sedangkan TL sebesar 16 dB pada frekuensi 1.250 Hz saja. Hasil uji psychoacoustic menunjukan bahwa, gabungan metode sonic crystal window dan noise masking relatif lebih disukai responden dengan mean preference score 4,79 dan nilai DR sebesar 2.49 dB. Rencana dan strategi implementasi dilakukan dengan beberapa tahap, yaitu penyusunan hardware secara agregat, tinjauan terhadap aspek kenyamanan ruang, dan tinjauan ulang terhadap sistem active noise cancellation.

Traffic is the dominant source of noise in urban areas and has a negative impact on the productivity and health of the population. Efforts to control noise then encountered several obstacles, including fluctuating amplitude, diverse composition, and covering a large area. This study aims to obtain a traffic noise control system with active noise control, passive noise control methods, and a combination of active noise control and passive noise control methods, as well as develop a plan for the implementation of active noise control and passive noise control methods as traffic noise controllers within the framework soundscape. Traffic noise signals are obtained through measurements and field recording in five locations and four time zones on Jalan Soekarno-Hatta Surabaya. Analysis of traffic noise signal characteristics was carried out using a soundscape approach based on spectral patterns, temporal patterns, and spatial patterns. The active noise control configuration which consists of an active noise cancellation system using the FxLMS algorithm can reduce sound by 15.6 dB and noise masking is able to cover noise with a threshold shift effect. Meanwhile, the passive noise control configuration in the form of a sonic crystal window shows an IL performance of 20 dB at a frequency of 500 Hz and 1.250 Hz while TL is 16 dB at a frequency of 1.250 Hz only. The results of the psychoacoustic test show that the combination of sonic crystal window and noise masking methods is relatively preferred by respondents with a mean preference score of 4,79 and a DR value of 2,49 dB. The implementation plan and strategy is carried out in several stages, namely the compilation of hardware in aggregate, a review of aspects of room comfort, and a review of the active noise cancellation system.
