Abstract
Son descritos un método y un aparato para detectar entrada no autorizada o accidental de un objeto en un cuerpo de agua, donde son determinadas la frecuencia a rango de frecuencias de las ondas sonoras en un cuerpo de agua generadas por la entrada del objeto en el cuerpo de agua. Entonces, las ondas sonoras que tienen la frecuencia generada en el cuerpo de agua son detectadas y se genera una forma de onda de salida eléctrica representativa de la amplitud de la onda sonora en la frecuencia. La amplitud de la forma de onda de salida eléctrica es posteriormente promediada, de modo que se genere una señal de alarma cuando la amplitud de la forma de onda de salida eléctrica excede la amplitud promedio por un valor predeterminado en un período de tiempo predeterminado. Una vez que se genera la señal de alarma se activa una alarma.
