Abstract

La presente solicitud describe un dispositivo de audio que tiene un efecto inhibidor sobre las ondas sonoras emitidas por una fuente de sonido de campo cercano dentro de un rango especificado y tiene un efecto de amplificación sobre las ondas sonoras emitidas desde una fuente de sonido de campo lejano fuera del rango especificado. El dispositivo de audio incluye un primer sensor de ondas sonoras para recibir una onda sonora y emitir una primera señal en base a la onda sonora; un segundo sensor de ondas sonoras para recibir la onda sonora y emitir una segunda señal en base a la onda sonora; y un circuito de procesamiento de señales acoplado al primer sensor de ondas sonoras y al segundo sensor de ondas sonoras para generar una señal de salida en base a la primera señal y a la segunda señal, en donde la sensibilidad de campo cercano del dispositivo de audio a una onda sonora es sustancialmente menor que su sensibilidad de campo lejano a la onda sonora.
