Esta Dissertação descreve um estudo empírico realizado com o intuito de
estabelecer correlações concretas entre distribuição espectral de energia em sons abstratos
e o uso de descritores semânticos específicos em português, numa investigação
transdisciplinar entre psicoacústica e linguística. Conceitos centrais, como “timbre”,
“som abstrato” e “descrição semântica” serão definidos e discutidos, com apoio numa
revisão de literatura nas áreas de perceção auditiva (e processos cognitivos subjacentes),
timbre sonoro e verbalização de som. Ao examinar a recorrência de descritores
semânticos específicos, esta Dissertação representa para nós a primeira etapa de uma
investigação mais alargada, no estudo da influência de vários parâmetros acústicos nos
processos cognitivos da perceção auditiva de sons não-referenciais. Para este fim, os
participantes do estudo empírico foram expostos a cinco sons sintetizados, cujos timbres
variavam exclusivamente na distribuição espectral de energia, avaliando cada amostra
sonora em escalas de magnitude para sete descritores semânticos. Demonstraremos
também a necessidade de estudos futuros acerca da semântica do timbre, ao averiguar a
influência de outras dimensões do timbre na perceção auditiva. Enquanto Dissertação de
Mestrado em Artes Musicais, uma consciência estética estará presente, refletindo acerca
do conceito de timbre no enquadramento das especificidades da música eletroacústica.
Trata-se da primeira investigação no campo da semântica do timbre dedicada à língua
portuguesa.
This dissertation describes an empirical study conducted with the aim of establishing concrete correlations between the spectral energy distribution of abstract sounds and the use of specific semantic descriptors in Portuguese, in a transdisciplinary research between psychoacoustics and linguistics. Central concepts, such as “timbre,” “abstract sound,” and “semantic description” will be defined and discussed, supported by a literature review in the areas of auditory perception (and the underlying cognitive processes), sound timbre and verbalization. By examining the recurrence of specific semantic descriptors, this dissertation represents the first stage of a broader research project on the influence of various acoustic parameters on the cognitive processes of the auditory perception of non-referential sounds. As such, the subjects of the empirical study were exposed to five synthesized sounds whose timbres varied exclusively in spectral energy distribution, evaluating each sample on magnitude scales for seven semantic descriptors. We will also demonstrate the need for future studies on the semantics of timbre by investigating the influence of other timbral dimensions on auditory perception. As a Master’s in Musical Arts Dissertation, an aesthetic conscience will be present, reflecting on the concept of timbre within the framework of electroacoustic music. This is the first research project in the field of timbre semantics dedicated to the Portuguese language.
