Intended Use

The Titan with DPOAE440 is intended for use in the audiologic evaluation and documentation of ear disorders using Distortion Product Otoacoustic Emissions. The target population for Titan with DPOAE440 includes all ages. The Titan with ABRIS440 is intended for use in the audiologic evaluation and documentation of ear and nerve disorders using auditory evoked potentials from the inner ear, the auditory nerve and the brainstem. The target population for Titan with ABRIS440 is newborns.

Device Story

Titan is a handheld audiometric platform for middle ear, inner ear, and brainstem testing. It functions as an impedance meter, OAE analyzer, or ABR screener depending on the installed license. For OAE, it generates acoustic stimuli in the ear canal; microphones detect cochlear outer hair cell responses. For ABR, it delivers short acoustic stimuli and records auditory evoked potentials via cutaneous electrodes. The ABR module uses an automatic detection algorithm to classify results as PASS or REFER. The device is used by audiologists, ENT surgeons, and hearing healthcare professionals in clinical or screening settings. It operates as a standalone handheld unit or connects to a PC via USB or Bluetooth for data management. Output is displayed to the clinician to document hearing status and assist in diagnosing ear or nerve disorders, facilitating early identification of hearing loss.

Clinical Evidence

No clinical data. Bench testing only. The device was tested against current international standards for OAE (IEC 60645-6) and ABR (IEC 60645-7) and found to conform.

Technological Characteristics

Handheld unit with cradle and PC software (Titan Suite). Connectivity via Bluetooth or USB. Features include OAE probe with auto-detection and ABR electrode interface. A/D resolution 24-bit, 5.38 Hz. Complies with IEC 60601-1 (safety), IEC 60601-1-2 (EMC), and IEC 60645-6/7 (performance).

Indications for Use

Indicated for audiologic evaluation and documentation of ear disorders (DPOAE440) in all ages, and ear/nerve disorders (ABRIS440) in newborns using auditory evoked potentials.

Regulatory Classification

Identification

The Titan is a combination of: - Audiometric device for measurement of aural acoustic impedance (IMP) (Cleared . under K083861) - Audiometric device for measurement of otoacoustic emissions (OAE) . - Audiometric device for measurement of auditory brainstem responses (ABR) ● The Titan can have one of three functions depending on license: The Titan IMP test is intended to change the air pressure in the external auditory canal and measure and graph the mobility characteristics of the tympanic membrane to evaluate the functional condition of the middle ear. The Titan OAE test generates an acoustic stimulus in the ear canal at a moderate intensity level. The stimulus vibrates a thin membrane in the cochlear, and activates the outer hair cells located on the membrane. This activation is propagated back through the middle ear as sound into the ear canal. Microphone(s) detects OAE-related sounds. The Titan ABR test produces a short acoustic stimulus and measures via cutaneous electrodes the auditory evoked potentials from the inner ear, the auditory nerve and the brainstem. The test uses an automatic detection algorithm to determine if an ABR is evoked in response to the short acoustic stimulus. The output of the device is either PASS (ABR detected) or REFER (ABR is not detected). The Titan with DPOAE440 is intended as clinical audiometer. The Titan with ABRIS440 is intended as a screener audiometer. #### Indications for Use The Titan with DPOAE440 is intended for use in the audiologic evaluation and documentation of ear disorders using Distortion Product Otoacoustic Emissions. The target population for Titan with DPOAE440 includes all ages. The Titan with ABRIS440 is intended for use in the audiologic evaluation and documentation of ear and nerve disorders using auditory evoked potentials from the inner ear, the auditory nerve and the brainstem. The target population for Titan with ABRIS440 is newborns. K103760 Section 05 p. 3 - 10 Image /page/1/Picture/18 description: The image shows the logo for Interacoustics.

No clinical tests were performed, but based on the fulfillment of the international standards for OAE and ABR, and the comparison to predicate devices we believe the device is safe and effective. ### Conclusion We have compared the intended use and performance characteristics with the predicate devices. The Titan was tested according to current standards and the differences found between the devices were related to functionality, not in relation to safety and efficiency. The Titan conforms to the current standards. The Titan with DPOAE440 and Titan with ABRIS440 were found to be substantially equivalent to the predicate devices in technological characteristics and indications for use.
