Noise Levels Along the Palembang–Indralaya Highway

Palembang – Indralaya highway is a cross-provincial road where motor vehicle activity is constant, causing noise and affecting settlements along the road. Constant exposure to the noise that exceeds quality standards (55 dB) stipulated in Environmental Ministerial Decree (KEP.48/MENLH/11/1996), can cause a variety of health problems, such as hearing loss and psychological disorders. Therefore, this study is conducted to determine the noise level along the Palembang-Indralaya road. This study used an observational approach through direct observations and measurements using the Mini InScienPro SQ-100 sound level meter. The noise level is measured at two locations, i.e., on the curb and in houses located along the highway. Based on the observations and measurements, the highest noise intensity was during the daytime (78.0 - 102.4 dB). The highest intensity of noise inside and outside the house are 74 and 90 dB, respectively. This is due to the high volume and activity of vehicles crossing the highway. The intensity of the noise received by the residents along the highway is above the quality standards, so as to handle the noise, trees need to be planted around the housing (barrier plants).

Penelitian ini bertujuan untuk mengetahui kontribusi dinding dan arsitektur ruang serta jarak gedung ke jalan terhadap reduksi bising dari luar kedalam bangunan, dan distribusi bunyi yang terjadi. Studi kasus pada 2 gereja yaitu gereja GMIM Kampus Unsrat dan gereja GMIM Bethesda Ranotana di Kota Manado. Sebuah sumber bunyi di letakkan di luar ruang dekat pagar pada jarak 12 m terhadap gedung, dengan kuat bunyi konstan namun bervariasi antara 60 sampai dengan 100 dB dengan tahapan setiap 10 dB. Kuat bunyi dihitung dan diukur pada setiap jarak 2 m diruang luar dan dalam Gereja. Pengukuran menggunakan alat sound level meter. Perhitungan menggunakan teori akustik ruang dan software I_Simpa. Hasilnya menunjukkan bahwa konfigurasi arsitektur selubung dan ruang bangunan kedua gereja tersebut dalam keadaan kosong hanya mampu mereduksi bising sebesar 2.2 dan 3.7 dB, dengan jendela terbuka. Dengan sumber suara 100 dB di ruang luar, hasil pengukuran di ruang dalam pada kedua gereja mencapai 69.3 dB(A) dan 56.4 dB(A). Rentang bunyi tersebut masih tergolong bising dan belum memenuhi syarat kenyamanan bunyi untuk jenis bangunan ibadah menurut SNI. Visualisasi distribusi bunyi dengan menggunakan software I_Simpa, menunjukkan peran bukaan pintu dan jendela yang menyebabkan kebocoran bunyi kedalam ruangan.Kata kunci: Akustika; bising; dinding; gereja Noise Level and Sound Propagation Due to Outside Sound at GMIM Church Unsrat Campus and GMIM Bethesda Manado ABSTRACTThis research aims to determine the contribution of walls and architectural interior, and the distance of the building to the road to the reduction of noise from outside into the building as well as the distribution of sound that occurs. Case studies on 2 churches: the GMIM Church of Unsrat Campus and the GMIM Bethesda Ranotana Church, both in Manado City. A sound source was placed outside the room near the fence at 12 m from the building. The sound source was constant but varied from 60 to 100 dB with steps every 10 dB. Sound reception was calculated and measured every 2 m distance at outside and inside. Measurements were carried out using sound level meter. Calculations by acoustic theory and I_Simpa software. The results show that the churches when room is empty, had only able to reduce the noise by 2.2 and 3.7 dB, with opened windows. When a 100 dB sound source was applied, the measurement results in the indoor of the two buildings reached 69.3 dB(A) and 56.4 dB(A). Graphical visualizations of sound distribution by using I_Simpa software, showed the role of door and opened window that cause sound leakage into the room.Keywords: Acoustic; church; noise; wall

Motorized Vehicles

Bogor Regency has an economic growth rate including the highest among cities and other districts around the Jakarta Capital Region. Regarding the condition of the vehicle population in Bogor district, the number of motorized vehicles in 2017 and 2018 experienced a growth of between 2% and 12%. In contrast to the growth rate of vehicles, the road growth rate is only 0.1% per year. Nurul Hidayah Mosque is located on Jalan Salabenda, the object of the author's research to find out how much influence the sound of motorized vehicles has on worship activities around the Nurul Hidayah mosque. In public transport car speed, motorcycle speed, and private car speed do not have a significant effect on the noise pollution produced. The noise level around the Nurul Hidayah Mosque, Jalan Salabenda Raya, Bogor Regency which has been measured the smallest is 56.4 dBA. This value exceeds the noise threshold of the Noise Level Standard Value for the Ministerial Decree, which is 55 dBA. So that it requires attention and cooperation from the government and the community to overcome the noise in the worship area. The calculation and analysis obtained is on the equation with the largest R Square value on the fourth day of the study, the third point (Sound Level Meter 3), with a contribution of 22.67%. Like the equation on the side, y = 73.251 + 0.004x1-0.311x2-0.003x3. The meaning of this equation is that if there is no decrease in the speed of motorbikes, private cars and public transport cars, the noise pollution level in SLM3 is 73,251 dBA. If there is an increase in the speed of public transport cars by 0.004, the decrease of motorbikes by 0.311, and an increase in the speed of private cars by 0.003, the noise pollution level will decrease by 0.31 dBA at SLM3.

The main objective of this study was to evaluate the variation in traffic equivalent noise levels as distance from the road intersection increases. To achieve this objective, traffic volume and equivalent noise level were monitored at 40 signalized intersections in Amman, the capital of Jordan. An integrated sound level meter (ISLM) was used to measure 1 min equivalent noise level along all approaches of the evaluated intersections. A total of 3326 noise measurements were performed. The collected data were analyzed to evaluate the variation of noise levels as distance from the intersection increases. The results indicated that equivalent noise levels were significantly affected by distance from the signal stop line. The equivalent noise levels at distances 50 and 100 m from the intersection were found to be 1.5 to 2.0 dB less than those at 0 m. While at 200, 250, and 300 m from the intersection, the monitored equivalent noise levels were found to be 3.8 to 4 dB higher than that at 0 m. At distances farther than 250 m, the measured equivalent noise levels tend to keep constant value of equivalent noise level as distance increased.Key words: noise, traffic, intersection, environment, pollution.

Noise refers to unwanted sound, which causes great discomfort to the ears, and is usually measured in decibels. Very high levels of sound above 100 dB cause permanent hearing loss. This study deals with effect of noise in the academic areas, University of Kufa, Kufa river campus (Faculty of Urban Planning, Faculty of Law, Faculty of Archeology). Kufa river campus area is exposed to several external noise types. Noise field data have been measured and collected for 98 station points. The noise intensity ratio was measured using the Sound Level Meter at three different times during the working hours in the morning hours (8.30-10.30), at noon (10.30-12.30), and in the afternoon from (12.30-2.30). The data were analyzed using the Excel program (percentile method) to obtain a noise level values at 10%, 50%, and 90% of data after arranging it ascendingly. The equivalent noise level (Leq) is calculate as well. The equivalent noise level data converts to GIS program form mapping and studying the spatial variation of noise intensity using a Spline interpolation method. The results showed that the effect of external noise is much greater than the effect of internal noise. The highest noise intensity at the points near the fence reached 94 decibels, and the lowest noise ratio was in the center of the faculty of Physical Planning, and the points near the green trees reached 45.1 db.
