The Departure of the Overtones of a Vibrating String from a True Harmonic Series
The Journal of the Acoustical Society of America, 1938The changes in frequency caused by variations in tension due to the amplitude of vibration of a wire are treated by the method of perturbations. The constraints introduced by the bridges at the end nodes as studied by Raman, and on the bending moments due to the stiffness of the wire are included in the treatment. The overtones do not, in general, form

Harmonic Sonification of High-Dimensional Continuous Data
Proceedings of the 30th International Conference on Auditory Display (ICAD 2025)High-dimensional continuous data is prevalent across empirical sciences but can be difficult to visualise. Sonification is a compelling alternative with many sonification approaches leveraging custom mappings of specific data features to auditory ...

Faraday discussions
Determining the bond anharmonicity constant (χeν̃e) and dissociation energy (De) at interfaces is challenging but important for understanding many fundamental physical and chemical processes.

Overtone series in variable density strings
Journal of the Acoustical Society of America, 2018The vibrational mode frequencies of a taut string depend on the form of its mass distribution. To lowest order, deviations away from a uniform mass density that are even about the center of the string cause shifts in the overtones away from harmonic ...

A transducer assembly for receiving a stimulating signal and producing ultrasound therefrom at one or more frequencies, over an ultrabroad bandwidth at each frequency, includes a front mass disposed about a central axis, and a back mass disposed about the central axis, laterally offset from the front mass.

The decay of excited stretching overtones of some local modes (C–H, C 3/4 C,C=C, C=O) attached to a hybrocarbon chain is theoretically investigated. The assumptions used in a previous paper [A. Lami and G. Villani, J. Chem. Phys. 88, 5186 (1988)] are critically examined and the model is improved by allowing the transfer of up to three quanta from the ...

Abstract A method is developed for calculating Bechmann's Number for the harmonic overtones of antisymmetric thickness-shear vibrations of crystal plates. In most cases the solution can be expressed as a simple, explicit formula. Values of Bechmann's Number for the AT-cut-quartz plate for the first ten modes are calculated for the ranges of ...

The vibrational contribution to the second hyperpolarizability (γ) of gas phase H2 was measured using electric field induced second harmonic generation. Measurements were made for the pure vibrational 3-0 Q(J) overtone transitions (v=0,J → v’=3,J for J = 0,1,2,3). Measured intensities were found to be 4-14% larger than ab initio calculations. The first

Two methods are described for calculating Bechmann's number for harmonic overtones of thickness/twist modes in rotated Y-cut quartz plates: one based on an exact solution of the equations of elasticity and the other based on an asymptotic form of the exact solution.
