Abstract
UN DISPOSITIVO Y PROCESO PARA EL ANALISIS DE LA REFLECTANCIA ACUSTICA DE LOS COMPONENTES DE UN OIDO IMPLICA DIRIGIR, DENTRO DEL CANAL AUDITIVO, UNAS ONDAS ACUSTICAS QUE CUBREN UNA GAMA DE FRECUENCIAS QUE INCLUYEN FRECUENCIAS RESONANTES DE LOS COMPONENTES DEL OIDO, COMO POR EJEMPLO LA MEMBRANA TIMPANICA. SE REALIZAN MEDICIONES SIN PRESURIZAR EL CANAL AUDITIVO, Y EL CONTACTO ENTRE EL DISPOSITIVO Y EL OIDO NO NECESITA SER HERMETICO AL AIRE. DE DICHA FORMA, EL PACIENTE NO SUFRE ESENCIALMENTE MOLESTIAS DURANTE EL USO DEL DISPOSITIVO. EL DISPOSITIVO DETECTA Y COMBINA LAS ONDAS INCIDENTES Y REFLEJADAS PARA PRODUCIR LO QUE SE CONOCE COMO UNA CURVA DE REFLECTANCIA ACUSTICA. LA FORMA DE UNA REGION DE LA CURVA DE REFLECTANCIA ACUSTICA SE MIDE ELECTRONICAMENTE CON OBJETO DE OBTENER UNA INDICACION DE LA CONDICION DEL OIDO QUE ES SUSTANCIALMENTE INDEPENDIENTE DE LA LINEA DE VISION ENTRE LA FUENTE DEL SONIDO Y LA MEMBRANA TIMPANICA. DICHA INDICACION SE BASA EN LA MEDIDA DE LAS CARACTERISTICAS DE RESONANCIA, O LIBERTAD DE MOVIMIENTOS, DE LA MEMBRANA TIMPANICA U OTRO COMPONENTE DEL OIDO QUE ESTA SIENDO ESTUDIADO. UNA DE DICHAS MEDIDAS ES LA VELOCIDAD DE CAMBIO DE LA REFLECTANCIA ACUSTICA CON RESPECTO A LA FRECUENCIA. DADO QUE LA RESONANCIA ORIGINA QUE APAREZCA UN VALOR CERO EN LA CURVA DE REFLECTANCIA ACUSTICA, ESTA MEDIDA DE LA VELOCIDAD DE CAMBIO ES PARTICULARMENTE INFORMATIVA SI SE MIDE CERCA DEL VALOR CERO. LA VELOCIDAD DE CAMBIO MEDIDA CERCA DEL VALOR CERO PODRA PRESENTARSE COMO UN ANGULO DE MEDIDA, UN GRADIENTE O INCLINACION, UNA MEDIDA DE ANCHURA U OTRA FORMA DE MEDIDA DE LA FORMA DEL VALOR CERO. EN UNA FORMA DE REALIZACION, LAS PENDIENTES MAS INCLINADAS EN CUALQUIER LADO DEL VALOR CERO SE USAN PARA DEFINIR UN ANGULO, CONOCIDO COMO GRADIENTE ESPECTRAL. EL DIAGNOSTICO DE UNA PATOLOGIA DE OIDO, COMO POR EJEMPLO LA PRESION ANORMAL, PRESENCIA DE FLUIDO EN EL OIDO MEDIO O UNA PERDIDA AUDITIVA CONDUCTIVA PODRA BASARSE SOLAMENTE EN DICHA MEDIDA. A CAUSA DE QUE LA VELOCIDAD DE CAMBIO DE UNA MEDIDA DE REFLECTANCIA ACUSTICA ES RELATIVAMENTE CONSTANTE PARA UN OIDO DADO, INDEPENDIENTEMENTE DE LA CALIDAD DE LA LINEA DE VISION HACIA LA MEMBRANA TIMPANICA, EL EFECTO, SI ES QUE SE PRODUCE, DEL ENTRENAMIENTO DEL USUARIO A DICHAS MEDIDAS SE REDUCEN SIGNIFICATIVAMENTE. DE DICHA FORMA, EL PROCESO Y DISPOSITIVO DE LA INVENCION SON UTILES EN MUCHOS TIPOS DE SITUACIONES DE DIAGNOSTICO CON RESPECTO A LA PATOLOGIA DE OIDO, PERO PARTICULARMENTE EN AQUELLOS CASOS QUE IMPLICAN EL ESTUDIO DE LOS OIDOS DE NIÑOS PARA PATOLOGIAS COMUNES, COMO POR EJEMPLO OTITIS, QUE PODRA REALIZARSE INCLUSO POR PERSONAL NO CAPACITADO.
