Indications for Use
The Titan Impedance System is an electroacoustic test instrument that produces controlled levels of test tones and signals intended for use in conduction diagnostic hearing evaluations and assisting in the diagnosis of possible otologic disorders. It features tympanometry and acoustic reflexes. The Titan Impedance System measures various acoustic properties of the ear, namely power reflectance, power absorption, transmittance, reflectance group delay, complex acoustic impedance and admittance, and equivalent ear canal volume. These measures allow the evaluation of the functional condition of the middle and outer ear. The Titan Impedance System is suitable for all populations including new-born infants. The Titan Impedance System is to be used by trained personnel only such as audiologists, ENT surgeons, doctors, hearing healthcare professionals or personnel with a similar level of education. The device should not be used without the necessary knowledge and training to understand its use and how results should be interpreted.

Regulatory Classification
Identification
An auditory impedance tester is a device that 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 device is used to determine abnormalities in the mobility of the tympanic membrane due to stiffness, flaccidity, or the presence of fluid in the middle ear cavity. The device is also used to measure the acoustic reflex threshold from contractions of the stapedial muscle, to monitor healing of tympanic membrane grafts or stapedectomies, or to monitor followup treatment for inflammation of the middle ear.
Special Controls
*Classification.* Class II (special controls). The device, when it is a tympanometer or auditory impedance tester that complies with FDA-recognized consensus standard ANSI S3.39, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 874.9.

### Technological Characteristics
Titan consists of a handheld unit named Titan, Titan Cradle and PC software (Titan Suite, Titan modules/ Titan Applications). The measurements are controlled by the handheld unit. A license system makes it possible within each configuration to select which functionality the user wants to be incorporated in the system.
A connection box (shoulder box) enables different types of accessories to be connected to the platform (depending on the module) The Titan platform can connect to PC software via a Bluetooth connection.
For measuring acoustic properties of the middle ear a probe is placed into the ear canal. The probe presents a calibrated tone or click sound into the ear canal and by recording the intensity and phase of the remaining tone or click in the ear canal it can be derived how much of the sound is absorbed by or transferred into the ear. Most common measures are:
- A tympanogram, in which the compliance/absorbance is measured as function of the presented frequencies and pressure in the ear canal;
- An acoustic reflex, in which the compliance/absorbance is measured over time as function of the presented frequencies while an acoustic activator is presented that above certain intensity is expected to cause a contraction of the stapedius muscle which in return is expected to cause a change in the compliance/absorbance of the ear.
The levels of the tonal and click sounds are to be calibrated in an artificial ear according to peak to peak equivalent signal level principles in IEC 60645-3
Titan with IMP440 WBT is IEC 60645-5/ANSI S3.39, Type 1 (Diagnostic/Clinical) acoustic impedance instrument
