Viola
Viola, ultra hızlı ve güvenilir timpanometri ile refleks testleri sunan bir tarama orta kulak analizörünü, hava yolu (AC), kemik yolu (BC) ve konuşma odyometrisi testlerini gerçekleştirebilen tanısal bir odyometre ile birleştiren kombine bir sistemdir.
MODELLER
Viola son derece kompakt bir tasarıma sahiptir ve yalnızca 2 kg ağırlığındadır; bu sayede tüm tanı istasyonu küçük bir taşıma çantasına sığabilir.
Viola, Basic ve Plus olmak üzere iki farklı modelde sunulmaktadır. Aşağıdaki tablo, her versiyonda bulunan testlerin genel bir özetini göstermektedir.
