Noise can occur anywhere, including at educational institutions. Noise research at educational institutions began to be studied a lot because of the negative impact on the teaching and learning process and disrupt the performance of teachers and students. Some studies show that schools or universities located on the edge of the road, show noise levels that exceed quality standards. This research was conducted at educational institutions located along the east Frontage Road Jl A.Yani Road, Surabaya, by measuring noise levels at 3 locations, in daylighting measurements with 4 measurement times (L1-L4). Data collection and processing was carried out by referring to the quality standard of KEPMENLH No. 48 of 1996. Data was measured using a sound level meter for 10 minutes for each measurement, with a reading every 5 seconds to obtain 120 data. Data processing results are compared with the standard noise level. The noise value at SD Margorejo I / 403 is 82.2 dB, UIN Sunan Ampel Surabaya is 79.76 dB, and SMK 3 Surabaya is 80.06 dB. The noise level value has exceeded the established quality standard, which has maximum of 55 dB for the educational intitutions area. The source of noise comes from the activities of motorized vehicles in and around educational institution that is quite crowded. Another cause of the high noise value is the train activities along the east frontage road Jl A.yani Surabaya, as well as the distance of the noise source with research location that relatively close.

One wildly used method to reduce and control the noise pollution in green city’s buildings is using sonic-absorbent panels. Their applications can be multiple, such as the insulation of buildings, acoustic barriers and fences along the highway or in front of supermarkets, hospitals and other public buildings. This paper presents a method for testing the behavior of sonic-absorbent panels in open-air environment. The work represents a carrying on of previous research about absorbent materials from gypsum family, tested in lab conditions. The experiment setup used a dynamic installation and as a sample a stand formed by six sonic-absorbent panels from special modeling alpha-gypsum plaster. This installation has been composed of two loudspeakers for emitting the sound at a well-defined frequency by the first laptop, the microphone for detecting and transmitting the signal to the second laptop for analyzing and processing the data. All operations were performed using MATLAB Programs, while a Data Logger Sound Level Meter type CENTER 332 was put on near the microphone to compare both results. The first experiment of acoustic stand has been realized by setting up the installation at a frequency from 50 Hz to 1250 Hz and altering the distance between loudspeakers and stand at 0.5m to 1m and 1.5m, respectively. The second experiment kept the same test’s conditions, while two and three layers of sonic-absorbent panels formed the stand, respectively, but at same distance from source of 0.5 m. In both tests, the results underlined the good sonic-absorbent properties of these panels, especially at medium and high frequency, which can recommend using the panels for multiple outside applications.
