SENTIERO ASSR

For the first time a hand held, portable lightweight device combines Tone and speech audiometry, TEOAE, DPOAE, AEP ABR & ASSR) in a Selectable modUlar format.
The emphasis is on test flexibility, ease of use, reliable
diagnostics and minimum test time.

The new binaural diagnostic ABR is typically used for NHS confirmational diagnostics, neurological diagnostics and objective threshold assessment.

Product Benefits

• Full Color Touchscreen! ! (ease of use)
• Flexibility
• Portability
■ Battery operated
• Long battery life (10 hours), fully charges in 4 hours
• Large memory (stores over 1OOO tests)
• Screening and diagnostic capabilities
• Extremely fast due to cutting edge technology and patented methods
• Objective and subjective testing in one device
• Different sets available to provide either ABR alone or a combination of ABR, ASSR, OAE, tone and speech audiometry on a screening or diagnostic level.
■ The option to combine ASSR and DPOAE hearing threshold estimation allows the acquisition of full audiogram from 125 Hz to 8 kHz in an objective and fully automated procedure!

All feautures of the SENTIERO 'Diagnostic and Screening' model are included as modules in the ADVANCED device.If necessary, all the SENTI feautures can be used with the SENTIERO.
