A case study regarding the statistical analysis on the evaluation of soundscape

Abstract

A wide-ranging study was conducted in order to develop an applied soundscape approach for the evaluation, conservation and rehabilitation of acoustic comfort in urban areas by the data from field and laboratory studies allowing the correlation of subjective and objective information's. The steps taken in developing the approach proposal were; deriving objective and subjective evaluations of the sound environment via field and the laboratory studies, statistically analyzing the data and correlating the results. The proposal was revised after being tested at first theoretically by using the first fields selected in Istanbul/Turkey, then practically by using new fields. The aim of this paper is to explain the statistical analysis part of the study. Therefore, the variance and t-test analyses between semantic differential test on site and jury test in laboratory and the simple regression analysis between the tests on two different environments and sound quality metrics, were made by using the data derived by field and laboratory studies.
