Abstract
The paper presents functionality and operation results of a system for
creating dynamic maps of acoustic noise employing the PL-Grid
infrastructure extended with a distributed sensor network. The work
presented provides a demonstration of the services being prepared within
the PLGrid Plus project for measuring, modeling and rendering data related
to noise level distribution in city agglomerations. Specific computational
environments, the so-called domain grids, are developed in the mentioned
project. For particular domain grids, specialized IT solutions are
prepared, i.e. software implementation and hardware (infrastructure
adaptation), dedicated for particular researcher groups demands, including
acoustics (the domain grid “Acoustics”). The infrastructure and the
software developed can be utilized mainly for research and education
purposes, however it can also help in urban planning. The engineered
software is intended for creating maps of noise threat for road, railways
and industrial sources. Integration of the software services with the
distributed sensor network enables automatic updating noise maps for a
specific time period. The unique feature of the developed software is a
possibility of evaluating auditory effects which are caused by the
exposure to excessive noise. The estimation of auditory effects is based
on calculated noise levels in a given exposure period. The outcomes of
this research study are presented in a form of the cumulative noise dose
and the characteristics of the temporary threshold shift.
