Abstract

One way to find out the acoustic performance of a room is by measuring the impulse response. These measurements will obtain  an overview of interaction between the sound source and the surface in the room, which can be described in a time sequence patterns of sound energy reflection at any point in the room as well as the reduction of sound energy at any time or any sound reflections information. This research aims to determine the amount of power response and impulse response of sounds produced by speakers. Variable in this research is sounds produced through a microphone and that go out through the speaker. To determine the power response, pink noise is measured, while the impulse response is measured using impulse signals. SPL meter is used to measure the power response and impulse response. The research is literature study and field observation. The result shows the impulse response measurement is not easily interrupted by frequencies from other sound sources. Meanwhile, power response is easily distracted by the frequency from other sound sources. Keywords: impulse signal, impulse response, pink noise, power response, SPL meter

Abstract

Abstrak Ketenangan merupakan suatu kondisi yang diperlukan di beberapa lokasi atau tempat tertentu, misalkan perpustakaan, tempat ibadah, dan sebagainya. Seringkali ketenangan ini terganggu dikarenakan adanya orang-orang yang mengobrol atau bahkan bersenda gurau. Alat ini dapat memberikan peringatan secara otomatis kepada pengguna ruangan untuk tetap menjaga ketenangan ruangan. Alat ini akan aktif saat mendeteksi tingkat kebisingan ruangan meningkat. Tingkat suara yang dikategorikan mengganggu ketenangan dapat diatur sesuai dengan tingkat kebisingan masing-masing yang dapat ditolerir. Dengan sistem ini diharapkan ketenangan akan tetap terjaga dan memberikan efek malu kepada pihak-pihak yang mengganggu ketenangan ruangan. Kata Kunci: Ketenangan Ruangan, Otomatisasi, Pemberi Peringatan  Abstract Tranquility is a necessary condition in some locations or certain places such as libraries and places of worship. The tranquility is often borekenwhen people talk excessively or even frolic. This tool can provide automatic alerts to the room users to maintain the room quietness. This tool will be activated when the noise level increases. The sound level categorized as disturbing can be adjusted according to the respective noise levels that can be tolerated. This system is expected to maintain the tranquility and give shame effect to the parties disturbing the tranquility of the room. Keywords: Room Tranquility, Automation, Warning Giver
