Escalas semánticas para la evaluación del ruido (II). Dimensiones subyacentes en los juicios subjetivos de estímulos sonoros. / [Semantic scales for the evaluation of noise (II). Subjacent dimensions in subjective judgments of sound stimuli]

ABSTRACT

Second stage of a research in which Osgoods Diferential Semantic Technique was used in two experiments with the following aims: a) to find out the subyacent dimensions of subjective evaluation of sound stimuli; b) to know if Osgoods Evaluation, Potency and Activity dimensions appear when sound stimuli are judged; c) to obtain a group of semantic scales that represent the found dimensions, which can be used in other researches in the same field. In the first experiment 37 scales were used by 98 Ss for judging 10 sound stimuli. In the second, 120 Ss performed the same task through 46 scales and 40 sound stimuli. Data of both experiments were processed by factor analysis method and a Varimax rotation was done. Having obtained 12 similar factors in both experiments the results were analized in a comparative way. Eight dimensions that explain the subject-sound stimuli relation were found. The other dimensions deal with the stimulis control, cognitive experience and structural caracteristics of sound stimuli, being the affective component also present in some of their scales. In the third stage the sound stimuli used will be analized through the found dimensions.
