Aplicação de método multi-critério para avaliação acústica de Bibliotecas Públicas

Abstract

The acoustic quality of libraries is presented through a multi-criterion algorithm. The criterion and its relative importance were gotten through a questionnaire to the libraries employees. The acoustic parameters used are: reverberation time, RASTI, sound absorption of the library entrance, sound isolation of the entrance to the reading room, weighted standardized level difference between the reading room and contiguous rooms, standardized sound level of the equipment noise, weighted standardized level difference of a façade and weighted standardized impact sound pressure level. The algorithm was tested on a sample of libraries in Portugal to obtain the Index of Acoustic Quality for Libraries.
