Diagnosis Of Acoustic Hazards Of The Environment And Its Identification Problems
Abstract:
Diagnostic procedures for control and evaluation of the state of environmental acoustic hazards have nu merous standard and legal regulations. They formalize how to perform control studies and assess the state of acoustic hazards in the environment . However, their implementation procedures have some unrecognized scientific and application potential. They can be associated with the failure to comply with the methodological requirements that apply to identification tasks carried out in the metric measurement space. The measurement dimension of the task of controlling acoustic hazards in the environment - based on decibel values - has a number of specific properties, projecting doubts about the currently used solutions .The problem undertaken in the article, analyzes the correctness of operations of decibel processing of measurement results from the point of view of algebra, used for modeling of recognized states of acoustic hazards of the environment. It focuses attention on the correctness of the estimation of exceedances of permissible noise levels by the Euclidean mea sure of the distance of the control evaluation result from the normative values. Discusses the shortcomings of the classification used in relation to the interpretation of the conditions of their perception by humans, as well as metrological considerations related to the evaluation of the uncertainty of the control result. I emphasize the need to look for new measures of exceedances of permissible values of noise levels in the environment, suitable for their perception by humans. The analyses and considerations presented in the article formulate a new pro gram framework for undertaking a broader discussion and research on the advisability of changing some of the implementation activities that are commonly present in existing procedures for identifying noise hazards in the environment. It outlines a certain research area that needs to be resolved in the area of implemented tasks of environmental acoustics.
