Titan Portable OAE/ABR

Titan – a new dimension in Newborn Hearing Screening

Imagine a handheld infant screener that will evaluate the entire auditory pathway from middle ear to brainstem, a product that will reduce your screening ABR test time by up to 50% and yet is so intuitively designed it requires only four buttons to do tympanometry, OAE & ABR. The ergonomic, lightweight Titan platform can do exactly that and much more.

The Titan Hardware

The Titan is a modular platform offering automated ABR, OAE & tympanometry testing. This flexible combination instrument allows you to create the perfect screening instrument and can also be configured to perform advanced clinical testing. The slim and ergonomic design allows for a true handheld operation, which together with the various available transducer configurations enable a strong focus on patient centered testing.


The DPOAE440 software module is available in either a screening or clinical version meeting the needs of any newborn hearing screening programme or diagnostic follow up clinic. The DPOAE440 can test from 500Hz-10KHz with user definable stop criteria incl. test time or point time, Signal-to-Noise Ratio, minimum DP level, residual noise & DP reliability. By using advanced real ear detection the Titan ensures precise stimulus intensity in any ear canal.


For screening purposes the Titan can be configured to give a fast and reliable PASS or REFER result between 500Hz – 6KHz.

If clinical testing is required, the manual mode enables the user to add extra test frequencies and add further sweeps to frequencies of special interest and also offers advanced DP/Input-Output testing for all frequencies available.

  • DP Reliability
  • Customisable protocols
  • DP-Gram or DP-I/O test available
  • Bar or Graph view
  • User controls for recording


The automated ABR software module for the Titan has been designed using the latest technologies available for fast and reliable automated ABR testing for infants.

The default stimulus in the ABRIS440 is the CE-Chirp® stimuli. Unlike the traditional click, the CE-chirp provides improved synchronization of the nerve fibers creating a response with up to double the response amplitude compared to a standard click allowing a much faster detection. The resulting test time can typically be reduced with up to 50% compared to traditional click stimuli. Optionally, the click or the new Hi-Lo frequency specific CE-Chirp® stimuli can also be selected. Moreover a sophisticated Bayesian weighted averaging is implemented, which optimizes the recording conditions in case of a fluctuating EEG due to an uneasy patient.

Apart from being among the quickest screeners available, it also provides reliable automated ABR tests with a sensitivity of 99,9% and a specificity of more than 96% making it the perfect instrument for newborn hearing screening.

The intuitive user interface and work flow from both the handheld unit and the Titan PC-Suite makes the instrument very easy to implement in any screening programme, as only very limited training is required in order to get familiarized with the instrument.

  • CE-Chirp, Click or Hi-Lo Chirp stimuli
  • Bayesian weighting
  • Results displayed as PASS/REFER
  • Three transducer options


The impedance module (IMP440) is available in a screening, diagnostic or clinical version allowing you to configure the Titan for the tests you need. The test battery features standard tympanometry, ipsi- and contralateral acoustic reflexes, reflex decay and reflex latency, as well as three Eustachian tube function tests. Together with optional high frequency probe tones (678, 800 and 1000 Hz), IMP440 is designed to meet and perform the most demanding of clinical requirements.

  • Automatic tympanometry testing
  • High Frequency probe tones
  • Ipsi & contra reflexes

Data Transfer and Reporting

Patient information can easily be uploaded to the handheld unit and transferred back to the Titan PC-Suite after having retrieved the test data. The results can either be printed using the sophisticated print wizard or saved in PDF format for insertion into EMR systems. The Titan is NoaH3 & HiTrack compatible.
