Resumo: | The parts that make up the guitar are made of the most varied materials to meet the needs related to each component, according to their specific functions to be performed on the instrument. One of the important aspects of current research in musical acoustics is the connection of the measurable physical properties of a musical instrument and its sound or tonal quality. The processing of acoustic signals from a string instrument, for example, can correlate the acoustic signals or sounds of the guitar with a mathematical operation of convolution or deconvolution by establishing relationships with its physical properties. Another technique used is to obtain responses in terms of frequency of vibration or time domain and the impulse excitation technique. The present work aims to evaluate through the separation of the signal referring to the frequency response of the guitar through the deconvolution of the sound signal generated when playing the instrument by the string signal recorded separately. It also seeks to establish the relationships with the responses obtained through the impulse excitation technique. And the results show that these two techniques can represent important techniques for characterizing materials used in string instruments such as the guitar. |

Uno de los aspectos importantes de la investigación actual en acústica musical es la conexión de las propiedades físicas mensurables de un instrumento musical y su sonido o calidad tonal. El procesamiento de señales acústicas de un instrumento de cuerda, por ejemplo, puede correlacionar las señales acústicas o sonidos de la guitarra con una operación matemática de convolución o deconvolución estableciendo relaciones con sus propiedades físicas. Otra técnica utilizada es la obtención de respuestas en términos de frecuencia de vibración o dominio del tiempo y la técnica de excitación por impulsos. El presente trabajo tiene como objetivo evaluar a través de la separación de la señal referente a la respuesta en frecuencia de la guitarra mediante la deconvolución de la señal sonora generada al tocar el instrumento por la señal de cuerda grabada por separado. También busca establecer las relaciones con las respuestas obtenidas mediante la técnica de excitación por impulso. Y los resultados muestran que estas dos técnicas pueden representar técnicas importantes para caracterizar materiales utilizados en instrumentos de cuerda como la guitarra.As partes que compõem o violão são feitas dos mais variados materiais para atender as necessidades referentes a cada componente, conforme suas funções específicas a serem desempenhadas no instrumento.

No presente trabalho objetiva-se avaliar através da separação do sinal referente à resposta em frequência do violão através da deconvolução do sinal sonoro gerado ao tocar o instrumento pelo sinal das cordas gravado separadamente.
