| Oídos artificiales |
 |
Esta Recomendación especifica las características electroacústicas de los oídos artificiales utilizados en telefonometría. Se especifican tres dispositivos: un tipo en la banda telefónica para mediciones de aparatos telefónicos tradicionales, un tipo de inserción y un tipo que reproduce fielmente las características del oído humano.Este último tipo (tipo 3) se especifica de acuerdo con cuatro configuraciones. En esta revisión de la Rec. UIT-T P.57 se modifican ligeramente los requisitos aplicables al tercer tipo de configuración [tipo 3.3 - Simulador de pabellón auditivo (oreja)], especificando su construcción con un elastómetro menos duro. |
