Palabras Clave: Trompeta Máster-Sib, latón-oro, latón-plata, campana de trompeta, calidad tonal, espectro armónico. Key Words: Máster-Sib trumpet, gold brass, silver brass, trumpet bell, tonal quality, harmonic spectrum. RESUMEN En el presente artículo se ha analizado el espectro armónico de la trompeta Máster en Sib de la firma Stomvi y su relació...
Palabras Clave: ruido en hostelería, nivel de interferencia verbal, ergonomía en restaurantes, privacidad acústica, SIL, LSIL. ABSTRACT. In this work we have carried out field surveys of the acoustic characteristics of a small restaurant in a rural house in the municipality of Petrer-Alicante, calculating the Level of Verbal Interference-SIL / LSIL...
Palabras Clave: Emisión sonora, espectro acústico, armónicos, parciales, pedagogía, trombón, nuevas tecnologías, presión intraoral, instrumento viento-metal. RESUMEN Se ha analizado la ejecución de Fa3 para distintitas situaciones donde la emisión tonal no era la correcta. Y se han comparado los resultados frente a una adecuada impostación. Los dis...
In the teaching sphere and especially in musical and artistic education it is frequent to learn by imitation. It is a primary instinct and inherent to human beings and of great value, since involuntarily we acquire new insight into the own the prosody of musical dialog and it favors the hearing development. In addition to the sound imitation, there...
After analyzing the influence of the dynamic masses done before, we now face determining the role they can play resonator bells (maxiclappers), introduced by Stomvi in the market, sound of a trumpet. It was found that the dynamic masses affect the impedance response equalizing somehow the harmonic series characteristic of the trumpet. Now it is stu...
This paper is based on the results obtained in the study of several rooms of speech, it was found that; under certain conditions directivity of the source location, the balance of the sound field presents significant anomalies not covered by a classical analysis under Sabine's ideas. This paper seeks to determine to what extent affects the verbal u...
Abstract During a comparative analysis of the impedance response of several trombones in the same tessitura, completed with a subjective survey, it was found that the Bach model 42 was working like one with less quality. A priori, it was one of the instruments that offered the greatest guarantee within the group studied. Against all odds, after per...
Traditionally execution with uncoupled mouthpiece to the instrument is used as emission technical exercise with great neurophysiological load, based on the mouthpiece-trumpet sequence. In this way, the sound fluctuation between the emission and the steady state and, therefore to a stable sound is produced in a very short time, that elapses from the...
In this paper, we propose the possibility of establishing limits for what natural reverberation are in a common room. At these limits we have called: Optimal reverberation and Saturation reverberation time. It is chosen Sabine expression for the reverberation time as the starting paradigm. From it and others assumptions like occupation of the surfa...
In this study are presented the objective results of the impedance response of some trombones in order to find their sound and timbre differences based on acoustic impedance curves. The results are also compared with the opinions included in an objective survey about the subjective evaluation after hearing a music passage recorded with everyone of...
The possibility of changing the impedance of the harmonic trombone registration within (Bb2, D4-Bb4) frequencies range, through the use of dynamic plugs that are screwed into the transpositor to cover it, is provided in this study. The purpose of the plugs, also called clappers, is to influence the homogeneity of sound register with a variety of dy...

The acoustic critical distance in a room, represents the match distance between the direct field and the reverberated field sound pressure levels. This concept is derived from the assumption of a statistically perfect performance for the diffuse sound energy; where the level of direct sound field pressure is governed by the inverse square of the so...
