This paper discusses a time-domain technique for synthesizing acoustic impedance at the diaphragm of a loudspeaker using a proportional-plus-derivative output feedback. The dynamics of electroacoustic transducers such as moving-coil loudspeakers can be readily controlled either by direct feedback principle on acoustic quantities, or by plugging a shunt network at the electrical terminals. Any c...

The propagation of the quasi-Lamb modes along a-SiC/ZnO thin composite plates was modeled and analysed with the aim to design a sensor able to detect the changes in parameters of a liquid environment, such as added mass and viscosity changes. The modes propagation was modeled by numerically solving the system of coupled electro-mechanical field equations in three media. The mode shape, the powe...

Fitting hearing aids to infants requires special consideration at each stage of the process. In the assessment stage, electrophysiological hearing threshold estimates must be adjusted appropriately so that an accurate hearing aid fitting can occur. Ear canal acoustics are also important to consider during the assessment stage of the hearing aid fitting process for infants. A strategy for measur...

Infrasounds, frequencies ≤ 20 Hz, occupying the sonic landscape beyond pitch, offer a wide terrain of musical potential to the contemporary electroacoustic composer, a potential that has so far been poorly defined or exploited. This paper is a brief tutorial on employing infrasounds in electroacoustic composition. Infrasounds possess musical potential within the auditory and tactile modalites a...

Artificial intelligence is a rich and still-developing field with many musical applications. This article surveys the use of artificial intelligence approaches in the pages of Organised Sound, from the first issue to the present day. Often, these approaches are designed with note-based composition in mind, but the research we present finds that artificial intelligence has also had a significant...

This work presents the complete synthesis procedure and circuit transformations needed to go from characteristic polynomials transversal network formed by electroacoustic resonators. filter topology allows possibility achieve any response in spite of limited coupling. is crucial for obtaining very wideband filters with arbitrary positions transmission zeros. Additional reveal flexibility such c...

This paper presents the Expressionist, a three-dimensional human interface designed to enhance human vocal expression through interactive electronic voice filtering. The system is composed of a two-handed magnetic motion sensing controller and a computer program that processes the recorded voice of the operator based on the performer’s body motion. This system is designed for electroacoustic vo...

In this article, the relations for electroacoustic phenomena, such as sedimentation potential, sedimentation intensity, colloid vibration potential, colloid vibration intensity/current, or electric sonic amplitude, are given, on the basis of irreversible thermodynamics. This formalism allows in particular to discuss the different expressions for concentrated suspensions found by various authors...
