As Serbia is in process of European integration, it dedicates particular attention to
the environmental protection, especially noise protection. According to the respective
policies, the Serbian Ministry of Education and Science funded the project “Development of methodologies and means for noise protection of urban areas” (acronym
“urbaNoise”) [6]. The project is realized by three major Serbian state universities,
University of Kragujevac, represented by Faculty of Mechanical and Civil Engineering Kraljevo, University of Niš, represented by Faculty of Occupational Safety
and University of Belgrade, represented by the Faculty of Traffic Engineering. The
project goals are:
• development of national noise assessment methodologies harmonized with EU;
• construction of laboratory facilities for testing of acoustic materials;
• design of modular noise barriers from waste materials;
• development of software tools for local noise mappings;
• development of national database of noise sources.
A database is an excellent tool of sharing data between scientific organizations
which collect and interpret data. However, databases about noise sources were not
developed in Serbia until this project.
Within the project “urbaNoise,” two databases for collection of data about noise
sources are developed. The first database [7] was aimed to be Serbian national
database for urban noise sources, intended for purposes of noise mapping [8, 9]. The
database presented in this paper is intended to describe the results of noise measurements of industrial and communal sources (presses, compressors, hammers, etc.) that
are not performed within the standard systematic environmental noise measurements.
During many of these measurements, it was not possible to fulfill the standard requirements for environmental noise assessment, but the acquired results are nevertheless
worthy of keeping for future studies.
The second section describes the basic mechanisms of noise sources. The third
section of the paper defines requests for creation of the database of industrial noise
sources, and the respective structure is described in the fourth section, while the
description of the database implementation is given in the fifth section.
2 Industrial Noise Sources
This section describes the basic noise generation mechanisms of industrial noise
sources, as well as some examples of the most common machines used in the working
environment. Machinery in the industry creates a serious noise problem. It is responsible for intense indoors as well as outdoors noise. This noise is due to machinery
of all kinds and generally increases with the power of the machines. The resulting
sound pressure level depends on the type of noise source, the distance from the source
to the receiver, and the nature of the environment. For a given machine, the sound
pressure level is determined by the part of the total mechanical or electrical energy
that is transformed into acoustical energy.
