ReSound Advanced Technology Series: Noise Tracker II and Wind Guard

---

1.  Noise Tracker II uses which type of noise reduction method? Co-modulation Lossless compression Spectral subtraction Modulation-based noise reduction

2.  For a top level product, the default Noise Tracker II setting in the fitting software for the All Around program is: Off Per Environment Strong Mild

3.  Which of the following factors does NOT affect Noise Tracker II parameters? Direction of the noise source Intensity level of the input signal Presence of speech in the input signal Frequency content of the input signal

4.  Technique(s) used to identify wind noise in Wind Guard is: Spectrum analysis- Wind noise tends to contain low frequencies Intensity level- Wind noise is always lower in intensity than surrounding background noise Correlation method- Wind noise is uncorrelated between front and back microphones Both A and C

5.  Noise Tracker II has a maximum attenuation of: 10 dB 12 dB 15 dB 18 dB

6.  Gain offsets for Wind Guard in the fitting software are as follows: Mild = 12 dB, Moderate = 6 dB, Strong = 0 dB Mild = 0 dB, Moderate = 3 dB, Strong = 6 dB Mild = 10 dB, Moderate = 8 dB, Strong = 6 dB Mild = 6 dB, Moderate = 3 dB, Strong = 0 dB

7.  When analyzing an incoming signal for wind noise, what is the maximum cutoff frequency the Wind Guard algorithm analyzes? 500 Hz 2000 Hz 3000 Hz 6000 Hz

8.  The optimal microphone setting to use when Wind Guard is activated is: Adaptive directional Omnidirectional Fixed directional Automatic directional

9.  How often does Noise Tracker II analyzes an input signal for speech/noise? Every 10 milliseconds Every 100 milliseconds Every 1 second Every 1 millisecond

10.  Which of the following environments are not adjustable in the Noise Tracker Per Environment setting? Speech (Loud) Speech in noise (Moderate) Music Quiet
