58. the torque force of the cable does not work against the probe direction and insertion If testing an infant prepare the probe by laying the probe cable along the infants body longitudinally with the probe head lined up with the infant s test ear An infant s ear canal is soft and collapsible Pull the pinna upward and backward to allow the insertion of the small red tip into the ear canal When the auricle is released the tip will sit firmly in the ear canal and the weight of the probe will be just enough to keep the probe in place The shirt clip on the probe cable may come in handy to support the probe head in place Ensure that you have completely inserted the eartip into the ear canal The end of the eartip should be flush with the opening of the ear canal A good insertion allows good seal of the ear canal and reduces external noise Eartips are designed for single patient use and should be disposed after each patient use or removal 2 6 Fitting a Foam Eartip into an Ear Canal First perform otoscopy to verify the ear canal is healthy and that you can visualize the eardrum Before the insertion work out any torque twist in the probe cable so that the torque force of the cable does not work against the probe direction and insertion Roll the foam between the thumb and the index finger to compress the foam Pull up and back on the pinna to straighten out the ear canal and then quickly insert the foam tip into the ear canal along the direction of th

60. x A Troubleshooting The majority of difficulties experienced while making measurements are due to a noisy patient or environment or a poorly fitted probe in the ear canal The acoustical equipment is very sensitive We recommend running the laptop on battery power during testing and disconnecting any peripheral devices such as laser printers 1 If the measurements are noisy and or no data is collected a Ensure the environment is as quiet as possible Sometimes no data is collected because all measurements are rejected for high noise levels b Ensure the probe cable is not moving against the patient Use the shirt clip or Velcro pad to stabilize the cable Drape the probe cable over the back of the chair or suspend it so it doesn t touch the patient A cable holder such as those used to hold up the cable of a domestic iron can be clipped onto a table to help keep the cable clear of the patient The cable should not rest on the patient as small movements can cause noisy measurements The cable should not be moved during a measurement c If the patient breathes noisily instruct the patient to breath through their mouth Sometimes this reduces noise d Check that the eartip is fully inserted and that the foam has expanded to fill the ear canal Gaps can cause low frequency noise leakage 78 79 e Run the laptop from battery power Electrical noise interference surges and drops on the main AC power supply can affect
