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

This is the third step of a research for which Osgood's 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.

Tercera y última etapa de una investigación (5, 6) cuya finalidad fue la construcción de escalas adecuadas para la evaluación subjetiva de estímulos sonoros, utilizando la Técnica del diferencial semántico. El objetivo de esta etapa fue caracterizar 40 estímulos sonoros a través de un grupo de las escalas antes mencionadas y teniendo en cuenta las dimensiones psicológicas subyacentes obtenidas por el análisis factorial de las mismas. Para ello se aplicó un programa especial de diferencial semántico obteniéndose los siguientes índices: puntaje escalar, polaridad, familiaridad y distancia inter-conceptos. Se determinaron los estímulos sonoros mejor caracterizados y las escalas más adecuadas para evaluar cada concepto

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

Second stage of a research in which Osgood's 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 Osgood's 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.

Segunda etapa de una investigacion en la cual utilizando la tecnica del diferencial semantico de Osgood se realizaron dos experiencias con el objeto de investigar: a) las dimensiones que subyacen en la evaluacion de estimulos sonoros; b) si las dimensiones EPA del mismo autor aparecen en el dominio estudiado; c) si existe un grupo de escalas semanticas representativas de las dimensiones encontradas. Dos muestras de sujetos juzgaron diferentes grupos de estimulos sonoros mediante escalas de adjetivos bipolares.Los datos obtenidos en cada experiencia fueron procesados por el metodo de analisis factorial, interpretandose los resultados en forma comparativa.Obtuvieron 8 dimensiones que explican la relacion sujeto-juicio-estimulo sonoro, comprobandose la importancia de las dimensiones afectivas en esta relacion

[Construction of semantic scales for the subjective evaluation of noise]. / Construcción de escalas semánticas para la evaluación subjetiva del ruido.

This is the first stage of a research the aim of which is to construct proper scales for the subjective evaluation of noise, using Osgood's Differential Semantic Technique. 137 adjectives were selected using two criteria. For the first criterium a method based on Gougenheim's and Hogenraad's researches was used. 200 subjects were asked to write 30 adjectives that could be used for qualifying sonorous stimuli. The frequencies of the adjectives given by the subjects were calculated and 25 of them were selected for being under the 10% limit of the probability, arbitrarily chosen as a criterium for the selection. For the second criterium 10 acoustic researchers were asked to write all those adjectives they considered important for noise evaluation. Thus, 112 adjectives were selected. The 137 adjectives got by the two criteria were judged by 15 university professors of different careers, for getting their opposites. A level of agreement of at least 6 of 15 judges was considered. 62 adjectives with their opposites were got and using other two criteria they were reduced to 37. A hypothesis was formulated grouping the adjectives into 8 factors taking into account the three universal factors: Evaluation (E), Potency (P) and Activity (A) according to the Differential Semantic Technique. Seven point scales were constructed with the adjectives. The construction of the scales, the selection of concepts, the application of them to a sample of subjects and data analysis will be the second stage of this research.
