Title (EN) ACOUSTIC MATCHING MATERIAL, METHOD OF MANUFACTURE THEREOF, AND ULTRASONIC TRANSMITTER USING ACOUSTIC MATCHING MATERIAL
(FR) MATERIAU D'ADAPTATION ACOUSTIQUE, SON PROCEDE DE FABRICATION, ET EMETTEUR UTILISANT CE MATERIAU
Abstract: front page image
(EN)An acoustic matching material (1) is used to match the acoustic impedance of a first object to that of a sound object when sound is transmitted from the first object to the second object. The acoustic matching material (1) includes a plurality of minute pieces (2), at least one of which is coupled to another piece (2) to form a gap in the acoustic matching material (1).
(FR)L'invention concerne un matériau (1) d'adaptation acoustique utilisé pour adapter l'impédance acoustique d'un premier objet avec celle d'un objet sonore lorsque le son est transmis à partir d'un premier objet vers un second objet. Le matériau (1) d'adaptation acoustique comprend plusieurs petits éléments (2), dont au moins un est couplé à un autre élément (2) de manière à former un espace dans le matériau (1) d'adaptation acoustique.
