Escalas semánticas para la evaluación del ruido. Tercera etapa: caracterización subjectiva de estímulos sonoros. / [Semantic scales for noise evaluation. Third stage: subjective characterization of sound stimuli]

ABSTRACT

This is the third step of a research for which Osgoods Differential Semantic Technique was resorted to in order to get suitable scales on a subjective evaluation of sound stimuli. Thus, a three-stage work was fulfilled. The first one dealt with the construction of seven-point bipolar scales starting from experimentally selected adjectives. The second one succeeded in finding the subjacent dimensions of the said scales by means of Factorial Analysis Method. The present stage aims at characterizing 40 sound stimuli through the discovered dimensions most representative scales. A special Semantic Differential Program was used to getting the following Index Scalar Scores, Polarity, Familiarity and Interconcept Distances. The interpretation of the Index showed the best characterized stimuli altogether with their affective meanings and their similarities and differences as well.
