Abstract

Soundscapes are affected by several factors and one of them is the activities done in the space concerned. People expect different acoustic environments for different activities, but there is no specific guidance for designing an ideal acoustic environment for different activities. This study aimed to identify ideal urban acoustic environments for four different activities: reading, relaxing, talking with friends, and playing with children. The ideal acoustic environment was evaluated using the soundscape composition concept. The concept was implemented by an acoustic environment simulator that enabled the respondents to compose their ideal acoustic environment and identify the perception of their composition. The sound source selection and perception rating were analyzed to understand the ideal acoustic environment and perception for different activities. This study identified the ideal soundscapes for four different activities and the perception expected to be present in the ideal environments for those activities. The result can be beneficial as guidance for urban soundscape design.

Abstract

In soundscape study, acoustic environment recording usually conducted using ambisonic microphone which record the sound from several direction simultaneously. Sonic environment analysis also includes the measurement of environmental noise which taken using Sound Level Meter. The measurement sometimes conducted in crowded urban area which is hard to take the recording systems and sound level meter at the same times. This study tries to analyse the performance of ambisonic microphone for noise measurement. The experiment is conducted by comparing the response two microphones (ambisonic and measurement microphone) in diffuse field. The experiment data shows that the frequency response of the ambisonic microphone is similar to the type 1 measurement microphone with 2,80 dB on average. The overall sound level measurement shows that the difference is not significant. The results indicate that the ambisonic microphone can be used for general noise measurement. Salah satu metode yang digunakan untuk analisis soundscape adalah dengan menggunakan rekaman (dibuat dengan mikrofon ambisonik) dan dengan pengukuran kebisingan yang dilakukan secara bersamaan. Analisis lingkungan sonik berbasis soundscape ini ini membutuhkan juga data terkait kebisingan dari lingkungan yang diambil dengan menggunakan Sound Level Meter (SLM). Permasalahan yang muncul adalah seringali pengukuran dilakukan pada daerah urban yang ramai yang tidak memungkinkan untuk membawa alat perekam suara dan SLM secara bersamaan.Penelitian ini bertujuan untuk menganalisis kinerja mikrofon jenis ambisonik untuk pengukuran kebisingan. Dari hasil pengujian pada medan difus menunjukkan bahwa respon frekuensi mikrofon ambisonik ini mirip dengan respon pengukuran dari mikrofon pengukuran tipe 1 walaupun terdapat perbedaan rata-rata sebesar 2,80 dB. Pengukuran kebisingan secara keseluruhan juga menunjukkan bahwa hasil pengukuran tingkat tekanan suara dari mikrofon ini tidak berbeda secara signifikan dengan hasil pengukuran tingkat tekanan suara dari mikrofon pengukuran. Hasil ini menunjukkan bahwa mikrofon ambisonik dapat digunakan untuk pengukuran kebisingan secara umum.

Abstract

Reducing CO2 emission through innovation discovery is essential to respond to the global warming issue. The research states that construction material contributes 11% of CO2 emission on building. Agricultural waste in Indonesia is plentiful, but it has not been used optimally, one of examples is corncob waste. The study to theoretically identify the absorption level on acoustic panel of corncob waste using two kinds of panel thickness dimensions composed of natural corncob through literature study and laboratory test of impedance tube by identifying the absorption panel coefficient phenomenon of corncob waste. The physical characteristic of corncob is porous, and this study found that there was a good absorption level in two dimensions of panel thickness of 3 cm and 5 cm. It was strengthened by the finding of a frequency shift phenomenon of two dimensions of panel thickness due to resonance in air cavity/gap among corncobs.

Abstract

Like other developing countries where traffic is a significant sound nuisance, traffic in Indonesian urban areas is boisterous. How this condition is regulated by the Indonesian government so that the community can live healthily and comfortably is a very crucial issue. Unfortunately, Indonesia has not had any sound environmental improvement since the regulation was enacted. Additionally, regulators and government officers who run the rule carelessly worsen the condition. This study aims to study how sound is regulated in Indonesia’s central and local governments, what types of sound or noise and levels are covered, and whether recent local regulations have been enacted to regulate sound in Indonesian cities. The study mainly uses quantitative, i.e., snowball or chain referral sampling techniques, to collect sound regulations applied in ten large and busy cities in Indonesia. Then, the qualitative stage was conducted based on the content of the rules. The data shows that the Indonesian government at both the central and regional levels does not have legal standing to regulate noise caused by the absence of noise regulation at the statutory level that can force those who violate the law to be punished. The only regulation is by the Minister of Environment, dated 1996, which is referenced nationally and adopted by most cities without or with minor modifications. This study found that (1) six of the ten cities regulate only one type of noise among various types of noise, (2) twelve of the 35 local regulations incorporate noise regulations into air pollution regulations instead of stand-alone regulations, (3) because provinces and cities adopt central regulations, the lowest noise level follows the central standard at 55 dB for settlement area without specific frequency ranges, (4) there is no straightforward procedure on how measurements to be carried out except in regulations stipulated by Yogyakarta province. There is also a fact that a standardized procedure for measuring noise is vital to be included in the regulation because unskilled government officials collected invalid data in dealing with a noise complaint leading to an unresolved situation.

Abstract

The condition of living plays a vital role in the online learning process at home. The residential need for support in the learning process was seen when Covid-19 forced students to study from their residences. However, residences not designed for students to carry out the learning process from home result in the focus/concentration in the process not running well. The study aims to explore the dimensions of residential perception that are by online learning needs. This study uses a quantitative approach with PCA analysis to find dimensions that need to be considered in the residence so that the learning process from home can run well. This study used student respondents living in Yogyakarta and Bandung so that the results of this study have a comparison of student perceptions in two different cities. The dimensions of perception of living conditions for online learning are audial quality, space comfort, space performance, and visual quality. Living conditions have differences in perception according to the type of residence in the form of boarding houses and houses. Ultimately, this study provides design principles that need to be considered in today’s residential design.

Abstract

This study aims to optimize the acoustic condition of a pyramidal ceiling mosque utilizing a simulation approach. The simulation was done using I-Simpa, simulating the room acoustic parameters of 15 m x 15 m x 5 m and a 5 m roof height of a mosque. The optimization was accomplished by varying the occupancy level and using absorbent materials. The best acoustic condition was defined as having a high level of speech intelligibility (C-50 > -2 dB) yet the longest possible reverberation time, especially at 500-4000 Hz. The simulation indicates that the speech intelligibility value increases with the number of filled rows, both with and without sound-absorbing material. On the other hand, the reverberation time is unaffected by the number of filled rows and is extended by using sound-absorbing materials. Hence, without sound-absorbing ceiling material, optimal conditions are attained when the mosque is fully occupied. Meanwhile, using sound-absorbing materials on the mosque's ceiling establishes optimal acoustic conditions for all occupancy levels. It demonstrates that using sound-absorbing materials improves the acoustic quality of the pyramidal-ceiling mosque.
