Frequency Lowering Fitting and Verification

---

1.  What is a basic definition of frequency lowering? Decreasing the amplitude of certain frequencies so they are less harsh A tool to improve the audibility of sounds for listeners with high frequency hearing loss and shifting a range of input frequencies into a different range of output frequencies Changing one's voice to a lower octave Turning down the volume on the radio

2.  Which one of the following is NOT a technique manufacturers employ to engage frequency lowering Frequency Translation Frequency Inversion Frequency Compression Frequency Transposition

3.  Which one of the following is NOT an option of the filtered "carrot passage" stimulus set? Speech 6300 Speech 3150 Speech 1500 Speech 4000

4.  The types of stimulus methodologies for testing frequency lowering discussed in this course are: Clinician vocalization of "S" and "SH" phonemes Modified calibrated speech passages that produce a distinctive high frequency "hump" White noise filtered to produce the idealized bandwidth of the "S" and "SH" phonemes All of the above

5.  Step One of the clinical procedure described in the course is: Identify the MAOF Range Check the audibility signature for the "SH" stimulus Determine the audibility of the "S" stimulus with frequency lowering off Complete a Speechmap fitting for 65dB Speech with frequency lowering off

6.  Step Two of the clinical procedure described in the course is: Turn frequency lowering ON and adjust to the MAOF Range Check the audibility signature for the "SH" stimulus Determine the audibility of the "S" stimulus with frequency lowering off Complete a Speechmap fitting for 65dB Speech with frequency lowering off

7.  Step Three of the clinical procedure described in the course is: Identify the MAOF Range Check the audibility signature for the "SH" stimulus Determine the audibility of the "S" stimulus with frequency lowering off Complete a Speechmap fitting for 65dB Speech with frequency lowering off

8.  Step Four of the clinical procedure described in the course is: Turn frequency lowering ON and adjust to place upper shoulder of 'S' within the MAOF Range Check the audibility signature for the "SH" stimulus Determine the audibility of the "S" stimulus with frequency lowering off Complete a Speechmap fitting for 65dB Speech with frequency lowering off

9.  Step Five of the clinical procedure described in the course is: Turn frequency lowering ON and adjust to place upper shoulder of 'S' within the MAOF Range Check the audibility signature for the "SH" stimulus Determine the audibility of the "S" stimulus with frequency lowering off Complete a Speechmap fitting for 65dB Speech with frequency lowering off

10.  When frequency lowering is utilized, how should care givers/therapists be informed? They should be told to be patient with the listener, as they will be irritable at first They should be careful to clean the aids thoroughly to avoid disturbing the frequency lowering settings They should be aware that the aids will sound different (distorted) when performing a listening check There is nothing unusual they need to be informed of
