STUDY OF NOISE LEVELS FROM VENTILATION SYSTEMS IN CORRIDORS OF RESIDENTIAL BUILDINGS

Abstract

Stained glass windows are applied in residential buildings more often nowadays, and therefore the natural ventilation is impossible to apply. The mechanical ventilation is good for apply in the situation. A lot of questions about the rationing of the noise in internal rooms in residential buildings are arisen. Residents complain the ventilation equipment noise from inter-corridor and the living area. Therefore, the question about study of noise generation in ventilation system and mechanical equipment^ that is applied in design, issue requires detailed research. For the study the question is necessary to do some research: analysis of foreign articles of noise regulation, measurement of noise in the inter-corridor and residential spaces, doing some calculations based on researching measurements, identification of normative noise characteristics for measurement data and carrying out measurements on noise measurement in the ventilation. This article presents the results of natural studies on noise levels from the operation of engineering equipment in the inter-apartment space of a residential building in the daytime (from 08:00 to 22:00 hours) and at night (from 00:00 to 06:00 hours) of the day. A theoretical study was carried out to compare the standard levels of sound pressure in residential buildings in different countries.
