Understanding and Treating Severe and Profound Hearing Loss

---

1.  The damage in severe or profound sensorineural hearing loss: May involve multiple structures May involve multiple physiological mechanisms Varies significantly from patient to patient May show up in variability in speech understanding performance All of the above

2.  Speech understanding variability in a population of patients with severe hearing loss: Is quite small Only shows up in speech in noise tasks Can show up in both speech in noise and speech in quiet tasks Cannot be measured None of the above

3.  Psychoacoustic deficits in the presence of severe or profound hearing loss may ne manifested in the domains of: Frequency resolution Temporal resolution Loudness range Word recognition performance All of the above

4.  Frequency lowering should be used: For some patients with severe or profound hearing loss for whom direct amplification is not enough For all patients with thresholds above 2000 Hz. Worse than 70 dB HL. Only for patients who show better thresholds in the high versus low frequencies Only for patients who cannot use compression None of the above

5.  Bi-modal fittings Include hearing aids of two different brands Include two hearing aids of the same brand, but two different model Include two hearing aids, one with frequency lowering and one without Include two hearing aids, one with compression and one with linear None of the above

6.  The role of Speech Guard E in severe hearing loss is: To maintain complete audibility for all speech sounds To preserve as much information, especially envelop information, in the amplified speech signal To move important high frequency speech information into the mid frequencies To avoid the need to use any compression None of the above

7.  The Copy & Keep approach: Is why Speech Guard E outperforms fast acting compression Involves copying the low frequency response and keeping it linear Involves copying certain parts of the high frequency response and reproducing it in the better functioning mid frequencies but without losing the original high frequency signal Involves copying only the vowel information and keeping it in the response but eliminating the consonants None of the above

8.  Oticon's Transitioning guidance: Helps with patients moving from one category of hearing loss to another Helps with patients moving from one make and model of super power devices to another Helps with patients moving away from the use of Speech Guard E Helps with patients moving into a product with feedback cancellation None of the above

9.  Frequency Composition In Dynamo and Sensei SuperPower: is off by default at the start of the fitting is on by default at the start of the fitting maybe off or maybe on depending on the patient's thresholds maybe off or maybe on depending on the patient's age none of the above

10.  In the presence of severe sensorineural hearing loss, compression: Is not appropriate Must be set to maximum to make all the signal audible Settings are totally predictable based on the audiogram Must be used carefully to balance audibility needs against the concern for "over compression" None of the above
