Noise pollution in buildings: valuation of acoustic comfort and your perception in the university library of Unesp – campus of Rio Claro (SP)

Abstract

In the urban environment, sometimes high sound levels are disguised amid the modern life stress, however, in certain occasions a few excess can represent grave decline in the activities efficiency, mainly, in those which request high levels of concentration and intellectual performance. The present study had its objective to evaluate acoustic condition in the university library of Unesp – campus Bela Vista, in Rio Claro (State of São Paulo). Therefore, were realized qualitative valuations applying questionnaires, complemented for quantitative valuations with acoustic mapping. Between the achieved results, was observed that the actual sound levels of library evaluated were in disagreement with the normative recommendation, causing low levels of usurious satisfaction. This positive correlation between the results of both valuations (qualitative and quantitative) reinforce the relevance of qualitative valuations in the search for environmental quality indicators, as well as its expressive potential of integration with the quantitative valuations, generating results more comprehensive and with more criterion.
