| Uso del simulador de cabeza y torso para pruebas de terminales manos libres y con microteléfono |
Esta versión revisada de la Recomendación UIT-T P.581 trata de los terminales manos libres (incluidos los de altavoz, altavoces y auriculares) y de microteléfono e incluye cláusulas para la calibración y utilización del simulador de cabeza y torso (HATS) para terminales de microteléfono y auriculares. Esta Recomendación especifica el uso del HATS para la evaluación subjetiva y objetiva de los terminales con altavoz (por ejemplo, la Recomendación UIT-T P.340). Define los montajes de pruebas, la calibración de la boca, la ecualización binaural y la suma de sonoridad, así como el método de calibración de cascos que ha de aplicarse para las pruebas subjetivas de audición por terceros que se describen en la Recomendación UIT-T P.832. |
