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.

Noise is one of the problems that often occur in urban areas due to the traffic condition. Noise in a building design depends on the choice of materials as sound absorbers. The type of sound dampening material that already exists is a porous material, a resonator, and a panel. The material often used as an absorber is porous materials, because it is relatively cheaper and lighter, especially to reduce the noise in the narrow spaces such as housing and offices. Various substitutes are made from cheap materials, such as the use of recycled materials of egg tray paper with the size of 40 x 40 centimeters. This is a quantitative research that will measure the place of egg tray paper in reducing noise, using a Sound Level Meter. The use of the egg tray paper is able to show an adequate acoustic quality as noise absorbers, with the average value of NR 22-26 dB.

Abstract. The method of determining the accumulation of condensate by registering the noise level in the respiratory circuit of ventilators is substantiated. According to the proposed method, the condition and performance of the apparatus is monitored during artificial lung ventilation and oxygen therapy. With hardware ventilation, an increasing turbulent flow of a water or gas stream is formed in the respiratory circuit, accompanied by an increase in the noise effect and vibration. An increase in the level of acoustic noise from fluctuations in the accumulation of condensate in gaseous media was recorded by an instrument for objective measurement of sound level a sound level meter. Indicators of noise effects reached a higher level on the wet circuit (the presence of condensation droplets or accumulations of mucus) of the liquid compared with the indicators obtained on the dry breathing circuit. The difference in recorded noise levels reached 10 dB, and increased from 37,73 to 47,36 dB. Areas of the respiratory circuit with the greatest degree of narrowing of the lumen and critical accumulations of water condensate and mucus are a source of turbulence in the air flow and increased noise. In conditions of prolonged artificial ventilation of the lungs, the rate of humidified air-gas flow is constantly changing, especially with hardware modeling of the phases of inspiration and expiration, and an increase in temperature in the humidifier chamber. The proposed technique is designed to identify critical levels of water condensate in the apparatus breathing circuits by recording the intensity of the increase in noise level and choosing the rational mode of operation of medical equipment. Data on the emerging critical situation are displayed on the sound level meter screen and inform medical personnel about the need to rehabilitate the circuit of the artificial lung ventilation apparatus. The primary field of application is resuscitation and intensive care units, medical transport teams during in-hospital or inter-hospital transportation, and surgical operating rooms during inhalation anesthesia.
