ReSound Sound Shaper: Understanding, Fitting and Verifying for 2016 and Beyond

---

1.  For a patient with aidable hearing through 4 kHz, and profound thresholds above 4 kHz, which scenario(s) should be considered for fitting Sound Shaper? The Strong setting (2.5k) should be considered, in order to maximize audibility of all high frequency sounds Sound Shaper should not be considered for this patient The Mild setting (4k) should be considered, in order to improve audibility of those sounds not aidable with conventional amplification Any Sound Shaper setting chosen during the fitting should not be changed once it has been set

2.  Which of the following statements about Sound Shaper settings in the fitting software is/are true? The recommended setting is based on threshold from 2-4 kHz and slope of the audiogram Sound Shaper is activated for all fittings Sound Shaper must be manually activated by the clinician Both A and C are correct

3.  Which of the following patients is Sound Shaper designed for? A patient who receives audibility of high frequency sounds from conventional amplification but wants more volume A patient who is experiencing feedback at 4kHz All patients with more than a mild high frequency hearing loss A patient who does not receive adequate audibility of high frequency sounds with conventional amplification

4.  Sound Shaper is a proportional frequency compression algorithm. Which of the following is true about proportional frequency compression? The compression ratio increases as the frequency of the input past the kneepoint increases Harmonic relationships for the sounds being lowered are maintained to preserve sound quality The full bandwidth of the hearing aid is amplified when the algorithm is activated High frequency sounds are transposed to a lower frequency region

5.  What is the first step in determining candidacy for Sound Shaper? Verify if the patient is receiving audibility of high frequency sound with conventional amplification Ask the patient if they are happy with their current hearing aid settings Automatically turn on if the fitting software recommends a specific Sound Shaper setting Use the age of the patient to determine if Sound Shaper is appropriate for the fitting

6.  What are the goal(s) of real ear verification of Sound Shaper? To ensure high frequency sounds are improving the patient's speech understanding ability To verify that high frequency sounds being lowered by the algorithm are audible to the patient To verify that conventional amplification does not provide adequate audibility To evaluate how much the patient likes the sound quality Both B and C are correct

7.  In which of the following cases may Sound Shaper be contraindicated? An adolescent patient with profound high frequency hearing loss An elderly patient who has experienced a decline in cognitive functioning A patient with a measured cochlear dead region in one ear An adult patient who was previously fitted with another manufacturer's implementation of frequency lowering

8.  The compression ratio of Sound Shaper refers to: The difference in amplitude between the original input signal and the output signal The difference in volume noticed by the patient when Sound Shaper is activated The difference between the original frequency of the input signal and the resulting lower output frequency Both A and B are correct

9.  Which of the following stimuli are especially useful for real ear verification of frequency lowering? Tone sweep stimulus Filtered speech stimulus in Audioscan Verifit Ling /s/ stimulus in Aurical FreeFit Both B and C are correct

10.  For a patient with asymmetric hearing loss: Sound Shaper can be set differently for each ear in the fitting software Consider choosing one Sound Shaper setting and using it on both sides Different Sound Shaper settings may be warranted in some cases All of the above are true statements
