Viola is a combo unit that integrates a screening middle ear analyzer offering ultra- fast and reliable tympanometry and reflex tests with a diagnostic audiometer capable of performing threshold and speech examinations in AC and BC. Small footprint, complete features set, great reliability and ease of use make Viola the perfect choice for professionals on the move and for installations where space is at a premium.
Viola is available in two models: Basic and Plus. The following table is an overview of the tests available on each version.
|Viola Basic||Viola Plus|
|Automatic acoustic reflex thresholds||Yes (Ipsi / Contra)||Yes (Ipsi / Contra)|
|Reflex test with fixed intensity||Yes (Ipsi / Contra)||Yes (Ipsi / Contra)|
|Reflex test with increasing intensity||Yes (Ipsi / Contra)||Yes (Ipsi / Contra)|
|Quick tests (tymp. + reflex tests)||Yes (2 tests)||Yes (2 tests)|
|Acustic reflex decay||No||Yes (Ipsi / Contra)|
|Pure tone audiometry||Yes||Yes|
Automatic test sequences
Speed up your middle-ear tests with the two available automatic exam sequences combined with special “fast” algorithms, all accurately developed to shorten the time needed for tympanometry and acoustic reflex assessments.
Ultimate hardware technology
Viola features an innovative pump technology for continuous air flow and a finely-designed probe. All combined with a powerful, DSP-based sound generator board for tympanometry and audiometry functions.
Very small footprint, just 2 Kg of weight: now you can carry your complete diagnostic station in a small suitcase!
Viola features an extremely light, small and sturdy metal probe, which can be very rapidly disassembled and cleaned. The probe is connected to the small Control Box, through which you can select the ear and start the exam.
One of the strength points of Viola is its display: an amazing high resolution, color LCD, on which you can clearly view the results of your examinations.
Embedded speech material
No more external player headaches! Viola Plus features an integrated flash memory for storing your speech material. The screen displays the word currently being pronounced.
