The Basic Skills of Speech Mapping

Please note: exam questions are subject to change.

1. Speech mapping is a form of: Sound field measurement Real Ear Measurement A subjective measurement All of the above
2. Speech mapping can be used to: Determine the output of a new hearing instrument fitting for comfortable input levels Determine whether an old hearing instrument fitting exceeds a patient's UCLs Troubleshoot the frequency area where feedback occurs All of the above
3. Differences between traditional Real Ear Measurements (REM) and speech mapping include: Traditional REM has the ability to use stimuli more meaningful to both the patient and those who are accompanying the patient Speech mapping gives specific single goal values per frequency whereas traditional REM does not Speech mapping allows the use of stimuli to measure hearing instrument fittings with all amplification parameters functional It is not necessary to do an unaided measurement using speech mapping
4. Using the Aurical Visible Speech, which stimulus is recommended to measure whether comfortable sounds are comfortable with all dynamic features of the hearing instrument(s) turned on? Pink noise Speech Swept tone Classical music
5. The reference microphone in the probe assembly: Measures the signal from the speaker at the ear Changes the signal from the speaker to maintain a specific level at the ear Never needs to be calibrated with the probe microphone Measures a value that is not made known to the practitioner
6. The signal strength at the ear is affected by: The level set using the volume slider position How far the patient is seated from the speakers The calibration of the speakers All of the above
7. Which is usually not acceptable when inserting the probe tube in the patient's ear? Using 20 mm as a guideline for the insertion depth for children Using the bottom of the earmold or shell as a guide for the insertion depth Using a very small amount of lubricant on the probe tube avoiding the area near the tip Running the probe tube through the vent of the earmold or shell
8. In the Aurical Visible Speech, the snapshot method of collecting data: Is always recommended Captures the response of the hearing instrument fitting over a length of time determined by the practitioner Is recommended when measuring a specific dynamic feature of the hearing instrument Will not change the measured results if taken at different points during the presentation of a speech stimulus
9. For which situation will the depth of the audibility area be the smallest? Mild gradually sloping sensorineural hearing loss Moderate gradually sloping sensorineural hearing loss Severe gradually sloping sensorineural hearing loss The audibility areas will be the same depth for all the above
10. For a sensorineural hearing loss falling precipitously to the severe loss range by 3 kHz, which of the following is NOT recommended? Consider distortion factors due to physiological damage of the ear when comfortable speech stimuli are in the target areas for frequencies of 3 kHz and higher Use the On Top Mode to place the speech mapping screen in the same window as the hearing instrument fitting software during fine tuning of first fit Use a speech stimulus of 50 dB to 55 dB to verify the measurement is at the lower level of the modified or re-calculated audibility area or at least greater than the thresholds Eliminate the loud sound measurement using the Airplane Stimulus file as recruitment will most likely be present
