Mejora de los sistemas de afinación en el oboe a través del estudio de los espectros armónicos de los acordes de 4ª y 5ª justa en la primera y segunda octava

Abstract

[EN] The purpose of this research is to study the physical and harmonic content of the sound produced by the oboe in the chords of the fourth and fifth joust, in the first and second octave, in order to develop a method to improve the tuning of the oboe. This work is composed of two distinct parts: the study of the harmonic content of isolated notes, played by a single oboist; and the harmonic content of the chords of the fourth and fifth joust, played by two professional oboists. Exhaustive measurements have been processed in order to obtain a pattern which is aplicable in different contexts. Acoustic measurements show the frequencies of sound (in hertz), in addition to the sonorous intensity (loudness). In the case of chords, these measurements correspond to the sound generated by their component notes and their relative intensities. This project has established experimental indexes beyond just collecting significant results for this study. For this reason, the knowledge obtained across these analyses will serve to develop a system to improve the tuning of oboes, which is readily extendible to any other instrument.

[ES] En este TFM se plantea el estudio del contenido armónico del sonido producido por un oboe. Se realizarán mediciones exhaustivas y su posterior procesado para obtener un patrón fidedigno, aplicable a distintas situaciones de contexto. Una vez realizado el proceso de medición, el objetivo final será el de aplicar los datos obtenidos para obtener un sistema de mejora de la afinación.
