Abstract
Se describe un aparato para medir una pluralidad de altavoces dispuestos en diferentes posiciones que comprende: un generador de señal de prueba (10) para generar una señal de prueba para un altavoz; un dispositivo de micrófono (12) que está configurado para recibir una, pluralidad de diferentes señales de sonido en respuesta a una o más señales de altavoz emitidas por un altavoz de la pluralidad de altavoces en respuesta a la señal de prueba; un controlador (14) para controlar emisiones de las señales de altavoz mediante la pluralidad de altavoces y para manejar la pluralidad de diferentes señales de sonido, de tal manera que un conjunto de señales de sonido grabadas por el dispositivo de micrófono está asociado con cada altavoz de la pluralidad de altavoces en respuesta a la señal de prueba y un evaluador (16) para evaluar el conjunto de señales de sonido para cada altavoz para determinar por lo menos una característica de altavoz para cada altavoz y para indicar el estado de altavoz usando la por lo menos una característica de altavoz para el altavoz. Este esquema permite la medición automática, eficiente y exacta de altavoces dispuestos en una configuración tridimensional.
