Solutions Guide: Accurio

Feedback/Whistling

Adaptive: Activate Adaptive Feedback Canceller.
Advanced: Decrease Soft Gain in Ch 3, 4.
Decrease gain/volume control.
Tips:
- Check ear canal for wax/debris.
- Check receiver direction and canal length.
- Consider vent reduction.

Barrel/Hollow/Echo/Plugged/Occlusion

Advanced: Decrease Soft Gain in Ch 1.
Compression: Increase Compression Ratio in Ch 1.
Compression: Increase Compression Ratio in Ch 2.
Advanced: Increase Soft Gain in Ch 3.
Tips:
- Enlarge and/or step back vent.
- Taper canal.
- Remake to shorten/lengthen canal accordingly.>
- Counsel.
- Increase overall gain and/or low frequency Soft Gain (Ch 1) (may be due to insufficient amplification).

Background Noise

Adaptive: Increase Adaptive Noise Reduction.
Advanced: Decrease Soft Gain in Ch 1.
Compression: Increase Compression Ratio in Ch 1.
Compression: Increase TK in Ch 1.
Advanced: Increase Soft Gain in Ch 3, 4.
Compression: Increase TK in Ch 3, 4.
Decrease gain/volume control.
Tips:
- If these programming solutions are insufficient, please call Audina to discuss the value of directional microphones (if not already in use).

Rushing Water/Fan Noise/Static/Circuit Noise

Advanced: Increase Expansion Ratio to 1:3.
Advanced: Increase Expansion Threshold.
Advanced: Decrease Soft Gain in Ch 1.
Advanced: Decrease Soft Gain in Ch 4.
Compression: Decrease TK in Ch 1.
Compression: Decrease TK in Ch 3, 4.
Tips:
- Increasing vent size may assist in resolving this issue.

Can hear but not understand / Speech is unclear

Advanced: Increase Soft Gain in Ch 3, 4.
Advanced: Decrease Soft Gain in Ch 1.
Compression: Decrease compression ratio in Ch 2, 3.
Advanced: Increase MPO.
Increase gain/volume control.
Adaptive: Increase level of Adaptive Noise Reduction.
Tips:
- This complaint is most often a result of the upward spread of masking or insufficient high frequency emphasis.

Own Voice
