Middle Ear Analysis
eTYMPUSB
Middle Ear Analyzer
The eTYMPUSB middle ear analyzer is a computerized middle ear analyzer designed for both routine and practical clinical use. The eTYMPUSB allows for the creation of customized test protocols by combining different tests from a suite into a single test path. For example, you can create a simple screening procedure and a more in-depth evaluation. The device features a compact, practical, and attractive design. Key features include: 226 Hz tympanic membrane measurement (standard), a small, lightweight, and easy-to-clean probe, various operating functions via signal separation, self- and contralateral reflex decay testing, Eustachian tube function (ETF) testing with intact and perforated tympanic membranes, measurement of the acoustic response to direct stimulation of a cochlear implant(CI), a scientific testing mode, automatic height correction for accurate permittivity values, storage of all relevant calibration values in the probe, and robust acoustic reflex detection.
Evoked Potentials
eABRUSB
The eABRUSB is a two-channel unit for measuring not only auditory evoked potentials (AEPs) but also vestibular evoked potentials (c- و oVEMP). Compact as a remote control, the eABRUSB is a fully integrated, portable device for measuring AEPs. Combining state-of-the-art electronics with a user-friendly interface, the eABRUSB ensures optimal results in both routine and clinical applications. It measures AEPs and vestibular evoked potentials (c- و oVEMP). The eABRUSB features integrated earphones and earpieces. The device automatically selects appropriate calibration values. The ability to create custom test protocols simplifies routine procedures. • Automated Assistance Functions: – Automatic electrode impedance control – Automatic gain control (AGC) – Tap, pulse, quick tap – Automatic noise rejection – Automatic shut-off function – Noise masking – Free selectable protocols – Easy-to-use curve manipulation – Automatic coupler detection – Free lifetime online subscription
Otoacoustic Emissions (OAE)
eOAE
The eOAE portable device measures transient acoustic emissions (TEOAE) and distorted acoustic emissions (DPOAE): When an auditory signal reaches the auditory system, the inner ear emits a very faint sound known as otoacoustic emissions. Transient otoacoustic emissions (TEOAE) and distorted otoacoustic emissions (DPOAE) are distinguished. Both TEOAE and DPOAE can be measured using the eOAE device. A special screening mode is also available for newborn screening.
The eOAE device also measures transient otoacoustic emissions. It features: • Easy cleaning of probe parts • Good sterilizability thanks to user-defined stop parameters • 4 adjustable profiles • Touchscreen • Time graph or frequency chart display • Optional printer available • Clear management of measurement data on the device as well • QWERTZ keyboard for easy data entry on the device • Graph and tabular display • Full integration with eDM Diagnostic Manager • Easy charging via docking station • TEOAE method • PC software for remote operation • Clear display of results.
