“…The reed mass and damping may also affect to a lesser extent the threshold pressure [20]. Finally, the timbre of the clarinet depends on the reed resonance frequency [21,22,23] and on the extent to which the reed beats against the mouthpiece lay (observed numerically [24] and experimentally [25]).…”

This paper deals with the subjective and mechanical characterizations of single cane reeds.Subjective tests performed by a single expert gave an estimation of the subjective descriptors "ease of playing", "brightness", "roundness", "projection" and "global quality". The mechanical characterization involved measurements of static compliance, dynamic compliance, resonance frequency and Q factor of the first vibration mode. Two sets of clarinet reeds were studied. The first set contained 50 reeds identical in cut, brand and strength. The second set contained 150 reeds with 3 different cuts but identical in brand, strength and static compliance. Results show that the perceptual space is almost bi-dimensional for the first set of reeds and mono-dimensional for the second set. For the first set, the two dimensions were largely created by the descriptors ease of playing (highly correlated to brightness) and roundness. For the second set (with a constant static compliance), the main dimension was created by all the descriptors, that are correlated. The study of correlation coefficients between subjective descriptors and mechanical parameters shows that the static and dynamic compliance are correlated with the descriptor ease of playing for set 1. For set 2, the correlations are too low to make a link between the perceptual space and the objective parameters.

Heterodyne holography is a variant of phase shifting holography in which reference and signal arms are controlled by acousto optic modulators. In this review paper, we will briefly describe the method and its properties, and we will illustrate its advantages in experimental applications.Ocis : 090.1995 : Holography : Digital holography ; 040.2840 : Detectors-Heterodyne.Citation : Michel Gross, Heterodyne holography with full control of both the signal and reference arms, Appl.

Single-reed musical instruments, such as the saxophone, generate sound through a complex interplay between the mechanics of the reed and the hydrodynamic and acoustic pressure in the instrument mouthpiece. To understand this complex mechanism, experimental data are lacking. This paper presents full-field, time-resolved measurements of strain and displacement of a vibrating saxophone reed, measured under mimicked realistic playing conditions. It is found that strain along the length axis of the reed is mainly expansive, except in a small zone near the tip where it becomes compressive when the reed touches the front edge of the mouthpiece. At the instant in the vibration phase where the reed touches the mouthpiece, significant bending and compressive strain appear along the direction perpendicular to the reed axis. Strain magnitudes in both directions are similar, with absolute values of 0.1%. Fullfield strain maps reveal subtle characteristics which are not revealed by displacement measurements. Bi-axial bending and strain may be an essential component in reed mechanics, which up till now has been fully neglected in modelling.
