Abstract
Se describen aparatos y técnicas para obtener información indicativa de una característica acústica de una formación que incluye el uso de un montaje de transductores que comprende una placa base, una primera losa piezoeléctrica y una segunda losa piezoeléctrica. La placa base incluye una primera región que se extiende axialmente en una primera dirección más allá de la primera y segunda losa piezoeléctrica a lo largo de un eje especificado de la placa base y una segunda región que se extiende axialmente en una segunda dirección opuesta a la primera dirección, más allá de la primera y la segunda losa piezoeléctrica. En varios ejemplos, una longitud de la primera región a lo largo del eje especificado es diferente a una longitud de la segunda región para proporcionar una configuración asimétrica. En varios ejemplos, se acopla un elemento de anclaje, en forma mecánica, a la placa base en una ubicación que corresponde a una ubicación de nodo de un modo de vibración acústico especificado.
