Please note: exam questions are subject to change.

1. What are characteristics of the Cochlear Amplifier upon which Sonics Speech Variable Processing DSP is modeled after? The outer hair cells of a healthy cochlea amplify soft sounds and control very loud sounds The inner hair cells of a healthy cochlea amplify soft sounds and control very loud sounds The outer hair cells of an unhealthy cochlea amplify soft sounds and control very loud sounds The inner hair cells of an unhealthy cochlea amplify soft sounds and control very loud sounds
2. In general, what are the characteristics of a sensorineural hearing loss? Significant loss for high-intensity sounds; Some loss for moderate-intensity sounds; Near normal perception for low-intensity sounds Significant loss for moderate-intensity sounds; some loss for high-intensity sounds; Near normal perception for low-intensity sounds Some loss for low-intensity sounds; significant loss for high intensity sounds; Near normal perception for moderate-intensity sounds Significant loss for low-intensity sounds; Some loss for moderate-intensity sounds; Near normal perception for high-intensity sounds
3. Using fast time constants, the traditional Speech Variable Processing DSP in Sonic hearing instruments: Addresses the need for optimum processing time in order to provide exceptional speech clarity and natural sound Addresses the need for optimum frequency resolution in order to provide exceptional speech clarity and natural sound Addresses the need for optimum time and frequency resolution in order to provide exceptional speech clarity and natural sound None of the above
4. The main difference between the traditional and the new Speech Variable Processing DSP is the option to control: Compression Ratios Compression Speed Compression Kneepoint None of the above
5. Phoneme Focus is the new name for Sonics traditional Speech Variable Processing DSP with: High Compression Ratios Low Compression Ratios Fast-acting compression Slow-acting compression
6. Envelope Focus is the name for Sonics new DSP option with: High Compression Ratios Low Compression Ratios Fast-acting compression Slow-acting compression
7. What components of a speech signal have a corresponding relationship to the auditory needs and abilities of patients with hearing loss? Speech Envelope and Temporal Fine Structure Carrier waves and Intensity level Fundamental Frequency and Short term spectrum Short term spectrum and Long term spectrum
8. What factors can influence auditory coding from the ear to the brain? Age Hearing Loss Cognitive Status All of the above
9. In an amplified signal: ___ Compression will preserve Temporal Fine Structure cues, which aids in enhancing frequency contrast; ___ Compression will preserve Envelope cues, which aids in enhancing loudness contrasts. Fast; Fast Fast; Slow Slow; Fast Slow; Slow
