Viola
Viola combina un analizador de oído medio de cribado con un audiómetro de diagnóstico, ofreciendo pruebas rápidas y confiables de timpanometría, reflejos, audiometría tonal y logoaudiometría, tanto en conducción aérea como ósea.
Modelos para cada necesidad
Viola se ofrece en dos versiones para adaptarse a las diferentes necesidades de los usuarios:
- Basic: Realiza timpanometría automática, umbrales de reflejo acústico automáticos (Ipsi/Contra), pruebas de reflejo acústico con intensidad fija y creciente (Ipsi/Contra), pruebas rápidas de timpanometría y reflejos (2 examenes), y audiometría tonal pura.
- Plus: Incluye todas las funciones del Basic y añade decaimiento del reflejo acústico (Ipsi/Contra) y audiometría del habla.
Material de voz integrado
Viola Plus elimina la necesidad de reproductores externos gracias a su memoria flash integrada para almacenar material vocal. La pantalla muestra la palabra que se está reproduciendo en ese momento.
Portabilidad excepcional
Viola destaca por su tamaño compacto y peso ligero (solo 2 kg). Esto permite transportar toda la estación de diagnóstico en una maleta pequeña, ideal para profesionales que visitan pacientes a domicilio o realizan pruebas en entornos móviles.
