Opis:
Nowadays, noise is considered as one of the most significant factors polluting the environment. It is classified in the first place among the indicators of the comfort of home, leisure and work. Therefore, more and more attention is paid to the need to study the sources and effects of noise on the environment and to develop effective methods of protection against nuisance and harmful sounds. Analysis of environmental factors is an especially important part of the process of spatial planning. The article covers characteristics of spatial and temporal differentiation of acoustic phenomena occurring within selected district of Lublin – the largest Polish city east of the Vistula River. Field measurements and analytical operations, which enable mapping noise, and consequently measuring the exposure of residents to the impact of abnormal sound levels, were made. There was also an attempt to evaluate the spatial development and its relationship with prevailing acoustic conditions. The collected results allowed developing recommendations for planning the city centre area acting as a standard. The need to design buffer zones to reduce the sound level near roads or locating residential areas away from sources of noise was underlined. The study should prove helpful in forecasting changes in the acoustic conditions and spatial planning and deciding on protection measures in urban areas.

Opis:
Urban noise is a main component in the deterioration of life quality for people in urban areas. This problem mainly affects those who periodically travel through high traffic areas. The first step in reducing environmental noise is to characterize the urban setting with acoustic metrology for its diagnosis and control. This document exposes the design, construction and characterization of a wireless urban noise measurement module. The device works as a low-cost node with the capacity to be replicated for the deployment of a network of wireless acoustic sensors that allows the elaboration of dynamic urban noise maps. Each module consists of an electrical autonomy system, a single board computer and a MEMS microphone. The project also includes the design of a web portal to display measurement results in real time. The low-cost system was calibrated and compared with a class 1 sound level meter used to measure urban noise in the Autonomous City of Buenos Aires (CABA). Global differences of less than 1 dB were obtained. Urban noise was measured near the National University of Tres de Febrero following guidelines of ISO 1996-2 standard. The performance obtained in the evaluation instance and the results of the comparison were satisfactory.
