Interacoustics Titan - Handling and Selection of Ear Tips

Titan Instructions for Use - EN Page 36
NOTICE
1. Careful handling of the instrument whenever in contact with a patient should be given high priority.
Calm and stable positioning while testing is preferred for optimal accuracy
2. The Titan should be operated in a quiet environment, so that measurements are not influenced by
outside acoustic noises. This may be determined by an appropriately skilled person trained in
acoustics. ISO 8253 Section 11, defines a quiet room for audiometric hearing testing in its
guideline.
3. It is recommended that the instrument be operated within an ambient temperature range of 15°C /
59°F – 35°C / 95°F
4. The headphone and insert phone are calibrated to the shoulder box of this instrument – introducing
transducers from other equipment requires a re-calibration.
5. Never clean the transducer housing with water or insert non-specified instruments into the
transducer
6. Do not drop and avoid other undue impact to this device. If the instrument is dropped or otherwise
damaged, return it to the manufacturer for repair and/or calibration. Do not use the instrument if any
damage is suspected.
7. Although the instrument fulfils the relevant EMC requirements, precautions should be taken to avoid
unnecessary exposure to electromagnetic fields, e.g. from mobile phones etc. If the device is used
adjacent to other equipment, caution must be taken to observe that no mutual disturbance appears.
Handling and selection of ear tips
When using the Titan probe and CIR55 contra phone, Sanibel ear tips must be used.
The Sanibel ear tips are single use only and should not be reused. Reuse of ear tips can lead to the spread
of infection from patient to patient.
The probe (and CIR55 contra phone) must be fitted with an ear tip of a suitable type and size before testing.
Your choice will depend on the size and shape of the ear canal and ear. Your choice may also depend on
personal preference and the way you perform your test.
When performing a quick impedance screening test you may choose an umbrella shaped ear
tip. Umbrella ear tips seal the ear canal without the probe tip going into the ear canal. Press
the ear tip firmly into the ear canal in such a way that a seal remains during the complete test.
For more stable testing, we recommend using an extension cord with a mushroom shaped
ear tip. Make sure that this ear tip inserts completely into the ear canal. Mushroom shaped
ear tips allow you to test ‘hands free’ from the Titan. This reduces the chance of contact noise
disturbing the measurement.
Refer to the “Selecting the Correct Ear Tip” Quick Guide included in the Titan Additional Information
document for an overview of ear tip sizes and selection.
