When preparing to test, attach the ear-tip to the brass coupler at the end of the sound tube. Then place the KUDUwave on the patient's head. Pinch, roll and deeply insert the ear-tips into the patient's ears. Bring the ear cups down, covering their ears and voila! You can begin testing.
It is simple, but, how you place the ear-tip is important too. Correct eat-tip selection and insertion is vital for the correct testing of patient.
The size and shape of the ear-tip plays a big role in how accurate the sound is presented. Your KUDUwave is calibrated to the specifications of these ear-tips, which ensures correct frequency and intensity is presented during a test. Incorrect ear-tips and placement can affect your results. To avoid inaccurate results follow these tips:
As shown on the ear-tip packaging, ear-tips need too be inserted deeply into the ear canal so that it sits flush with the opening of the ear canal. This ensures the proper sealing of the ear canal and thus assists in attenuating ambient noise. Deep insertion also changes the distance between the end of the sound tube and the ear drum. If this distance is not within an acceptable range, the tones being presented will not conform to the standard the device was calibrated to.
The KUDUwave ear-tips come in two sizes, indicated by their colour. The yellow ear-tip is recommended for most ear canals as it will ensure the proper fit and seal of the ear canal. The beige ear-tip is designed to accommodate patients with small ear canals, i.e. children and a small percentage of adults. Beige ear-tips are not to be used in place of yellow ear-tips for convenience and ease of the clinician. If the ear-tip is too small it can greatly affect the results of the test, particularly in the low frequencies.
For easier insertion of the yellow ear-tip, make sure it is pinched and rolled to the smallest diameter when inserting. It can be rolled into a shape smaller than the size of the beige ear-tip. Once it is inserted into the ear canal, it will slowly return to its original size filling the ear canal and sealing it tightly. To stretch and open the ear canal a little bit more, pull the pinna backward and upwards. You can also wiggle the sound tube a little to ensure a perfect fit.
** Tip: When rolling the ear-tip, be careful not to expose the black tubing in the centre. This may cause discomfort when inserting the ear-tip.
Inspection of your ear-tip is very important. Make note that there are no defects in the foam or any black tubing which extend further than the coloured foam. This affects the length of the ear-tip connected to the sound tube and greatly affects the tone being presented. Your ear-tip should not be squashed, bent or previously used. Ear-tips are designed as a consumable item. For obvious hygiene reasons, an ear-tip should only be used once and then disposed of in an appropriate manner.
Purchase your ear-tips from accredited retailers and make sure they are approved and have the relevant seals.

Disposable ear-tips act as a barrier between the ear probe and the patient. Old ear wax and cleaning solutions can damage the ear probe permanently. Cleaning solutions also damage the foam of the ear-tips and can lead to incorrect readings. It is an irresponsible risk to clean ear-tips for re-use, as cleaning solution or wax can end up inside the ear probe and give incorrect results. Any perceived cost saving will not outweigh the risks to the device and more importantly, the patient.
