The practical, flexible choice for audiologists and ENT physicians

Designed for objective evaluation of the auditory function, the Octavus is a PC-based system with its own patient database and the option of interfacing with a standardized patient management system such as GDT.

Setup is very easy just install the software on a PC and connect the hardware unit via the built-in serial port or a USB/RS232C adapter. The electrodes connect directly to the hardware unit no extra boxes like most other systems.

Weighing a little more than 5 lbs. (2.5 kg), Octavus is very portable when used with a laptop PC. The system is ideal for use in conjunction with infant screening programs.

One- or two-channel system

Octavus is available in one- or two-channel versions so that the system can be tailored to individual requirements. If you choose the one-channel solution, you can always upgrade your system to the full two-channel version subsequently.

Output options include Holmco, HB-7 or ME70 headphones, and E-A-RTONE® 3A insert earphones.

Flexible, intuitive software

The user-friendly Octavus software runs under all recent Windows versions and is very easy and intuitive to use. And comprehensive online help is always just a click away.

A colored two-buffer correlation bar is provided to help you achieve reliable and easy to evaluate measurements. Traces may be superimposed, a feature that further facilitates evaluation and optimizes the use of two-channel technology. Finally, auto sequences can be set up to optimize workflows.

Potential application for the Octavus ABR system

• Diagnosis of retrocochlear disorders such as the detection of vestibular schwannoma or acoustic neuroma (tumor on the VIIIth cranial nerve).
• Differential diagnosis: differentiation between conductive, retrochochlear and cochlear hearing loss.
• Determination of hearing thresholds using click stimuli.
