The aim of this paper is robust identification of smart foam, as an electroacoustic transducer, considering unmodeled dynamics due to nonlinearities in behaviour at low frequencies and measurement noise at high frequencies as existent uncertainties. Set membership estimation combined with model error modelling technique is used where the approach is based on worst case scenario with unknown but...

Theoretical and experimental analyses of a cell that measures the viscosity of liquids using longitudinal to shear wave mode conversion are presented. The measurement method is based on the determination of the complex reflection coefficient (magnitude and phase) of shear waves at a solid-liquid interface. The cell is composed of an ultrasonic transducer, a water buffer, an aluminum prism, a PM...

Design and modeling are key steps in the value chain of Capacitive Micromachined Ultrasonic Transducer (CMUT) arrays. Although CMUT array element models very powerful, most them still limited their use as tools for electronic design assistance. The electroacoustic equivalent circuits developed mainly based on a distributed-element approach while lumped-parameter electrical better suited softwar...

An evaluation of the performance a recently developed formulation (lead-free) Sodium-Bismuth titanate – Barium Titanate (NBT-BT) piezoceramic is presented through construction and testing several immersion transducers based around new material “Pz12” from CTS Ferroperm (Kvistgaard, Denmark). Results are intended to yield insight into applicability this lead-free for use within industrial, NDT, ...

The object of research is thermal processes in Langevin-type piezoceramic electroacoustic transducers (PET), taking into account the housing. heat up during operation. Overheating converter leads to negative consequences, accompanied by a change parameters, characteristics device, as well failure converter. Or limitation on duration and mode operation, output power, current, amplitude speed osc...

The key question posed here is how listeners experience meaning when listening to electroacoustic music, especially how they experience it as art. This question is addressed by connecting electroacoustic listening with the ways that the mind constructs meaning in everyday life. Initially, the topic of the everyday mind provides a framework for discussing cognitive schemas, mental spaces, the Ev...

Wearable sensor technology and aerial dance movement can be integrated to provide a new performance practice and perspective on interactive kinesonic composition. SALTO (Sonic Aerialist eLecTrOacoustic system), is a system which allows for the creation of collaborative works between electroacoustic composer and aerial choreographer. The system incorporates aerial dance trapeze movement, sensors...

Often played in traditional music performance formats, much recent telematic electroacoustic music focuses on the relationships between people/machines and geographically distributed cultures/spaces/players, and/or it adopts electroacoustic music’s historical concerns with natural environmental sound art or space manipulation. But a more suitable environment for telematic art works is perhaps f...

The intent of this paper is to describe the first stages of potentially ongoing collaborative research between the United States Naval Research Laboratory's Underwater Sound Reference Detachment (USRD) and France's DCN IngCnierie centre Sud DCpartement Lutte Sous-Marine (DCNISUDPLSM). The immediate focus of this collaborative work is on high Q electroacoustic transducer calibration in reverbera...
