Solutions Guide: Intuition 2 / Simplex 2P BTE

Feedback/Whistling

Equalizer: Decrease Gain at 2.5 to 3.5 kHz.
Advanced: Activate Feedback Notch at 4000Hz.
Equalizer: Decrease gain at 4.5 to 6.5 kHz.
Equalizer: Decrease gain at 3 to 6.5 kHz.
Basic: Slide High Cut Corner to 2500 Hz.
Tips:
Check ear canal for wax/debris.
Check receiver direction and canal length.

Barrel/Hollow/Echo/Plugged/Occlusion

Basic: Move Low Cut Corner to the right.
Compression: Increase Compression Ratio in Ch 1.
Compression: Increase Compression Ratio in Ch 2.
Equalizer: Increase Gain at 1.5 - 3.5 kHz.
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

Basic: Move Low Cut Corner to the right.
Compression: Increase Compression Ratio in Ch 1.
Equalizer: Increase Gain at 1.5 - 3.5 kHz.
Advanced: Increase Expansion Threshold.
Decrease overall Gain.
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 Threshold.
Compression: Decrease TK in Ch 1.
Compression: Decrease TK in Ch 2.
Equalizer: Decrease Gain at 1 kHz.
Equalizer: Decrease Gain at 4 kHz and above.
Tips:
- Increasing vent size may assist in resolving this issue.

Can hear but not understand / Speech is unclear

Equalizer: Increase Gain at 1.5 - 3.5 kHz.
Basic: Move Low Cut Corner to the right.
Compression: Decrease Compression Ratio in Ch 2.
Advanced: Increase MPO.
Increase overall Gain.
Tips:
- This complaint is most often a result of the upward spread of masking or insufficient high frequency emphasis.

Own Voice

Nasal/Stuffy

Compression: Increase Compression Ratio in Ch 1, 2.
Basic: Move Low Cut Corner to the right.
Equalizer: Increase Gain at 1.5 - 3.5 kHz.
Advanced: Increase MPO.
Tips:
- If you suspect this complaint is due to the occlusion effect, please refer to barrel/hollow/echo/plugged/occlusion solutions.

Booming/Echo

Advanced: Decrease MPO.
Compression: Increase Compression Ratio in Ch 1.
Basic: Move Low Cut Corner to the right.
Tips:
- If you suspect this complaint is due to the occlusion effect, please refer to barrel/hollow/echo/plugged/occlusion solutions.

Tinny/Harsh/Raspy

Advanced: Decrease MPO.
Compression: Increase Compression Ratio in Ch 2.
Equalizer: Decrease Gain at 3 kHz and above.
Advanced: Activate Feedback Notch at 4000Hz.
Tips:
- If you suspect this complaint is due to the occlusion effect, please refer to barrel/hollow/echo/plugged/occlusion solutions.
