Abstract

Environmental Noise Dispersion Model (ENDM) simulates outdoor sound prorogation and predicts noise levels from known noise sources for close and distant locations. The Model calculates attenuation due to noise source enclosures and other noise control measures, for distance from the source to the receiver, for the noise source size, type and directivity, for barriers and natural topographical features and for sound absorption in the air. In practice the physical environment will usually not be fixed, but will be characterized by constantly varying conditions. These variations in real world conditions will subsequently cause the actual sound field to vary in time and space. Thus it is important to recognize that the output of an Environmental Noise Model (ENM) will only represent an estimate of the range of actual environmental noise levels that could occur in time and space. Therefore verification of ENDM is essential step in increased model confidentiality. By comparing results calculated and measured on site during the model development and model adjustment, compliance between measurement and calculation results could be obtained. This paper presents steps of ENDM verification in mining sites.
