Abstract
UN MICROTELEFONO ANTIRRUIDO QUE CONSTA DE UN RECEPTACULO QUE DEFINE UN AURICULAR (2) Y UNA BOQUILLA (3) QUE ALOJA A UN MICROFONO DE GRADIENTE DE PRESION DE PRIMER ORDEN (M). EL RECEPTACULO TIENE DOS PUNTOS SENSIBLES A LA PRESION (H1 Y H2) EN LA REGION DE LA BOQUILLA (3), LOS CUALES QUEDAN CONECTADOS AL MICROFONO (M) MEDIANTE UNOS CONDUCTOS (5). LOS PUNTOS SENSIBLES A LA PRESION (H1 Y H2) SE ENCUENTRAN SEPARADOS ENTRE SI UNA DISTANCIA PREDETERMINADA QUE ES LO SUFICIENTEMENTE AMPLIA COMO PARA PERMITIR QUE UNAS SEÑALES DE VOZ GENERADAS LOCALMENTE PRODUZCAN UN GRADIENTE DE PRESION ENTRE LOS PUNTOS SENSIBLES A LA PRESION MIENTRAS QUE UNAS SEÑALES SONORAS PROCEDENTES DE FUENTES DISTANTES PRODUZCAN PRESIONES SUSTANCIALMENTE IGUALES EN LOS PUNTOS SENSIBLES A LA PRESION, CON LO QUE, CUANDO SE ENCUENTRA EN FUNCIONAMIENTO, LA SALIDA DE BOQUILLA ES SUSTANCIALMENTE POR COMPLETO LA QUE RESULTA DE LAS SEÑALES DE VOZ GENERADAS LOCALMENTE.
