Please note: exam questions are subject to change.

1. Which sound processing technology improves the signal-to-noise ratio to improve performance in noise? HiRes P HiRes Optima HiRes Fidelity 120 ClearVoice
2. HiResolution Fidelity 120 and HiRes Optima sound processing strategies utilize current steering to provide additional __________ information. Intensity Spectral Temporal None of the above
3. __________ determines how much of the sound captured by the microphone is delivered by the system. Input Dynamic Range (IDR) Gain Pulse width Automatic Gain Control (AGC)
4. Which of the following statements about SoftVoice is not true? Input sounds falling below threshold (i.e. low-level background noise) will be removed SoftVoice places low-level sounds to a higher position in the electrical dynamic range. SoftVoice is a sound-cleaning feature designed to remove unwanted noise from low intensity input. SoftVoice is available for Naida CI Q90 only.
