Soundpro 2.0

Customizing Soundpro 2

This section covers customizing the Soundpro 2 feature, which manages microphone modes and directionality.

Soundpro Mode

The default setting is 'Balanced Focus'. Changes can be made for environmental sounds or speech components.

1. To focus on environmental sounds, move the slider to the left (3 steps available). This favors less directional microphone modes, beneficial in demanding situations.
2. To focus on speech components, move the slider to the right (3 steps available). This favors more directional modes and stronger noise reduction, beneficial for understanding speech in noisy environments.

   [Images: Screenshots illustrating the Soundpro 2.0 interface with sliders to adjust focus between environmental sounds and speech.]

Manual Offsets

Manual offsets affect acoustic environments. They are applied in 1 dB steps.

1. Select the component to change.
2. Select a number of handles.
3. Click the up or down arrows as needed.

   [Image: Connexx software showing the interface for adjusting manual offsets for Soundpro 2.0.]

Manual Offsets - Bluetooth

Adjust the Bluetooth audio streaming response. Changes carry over to the Audio Streaming tab.

Basic Tuning

The Basic Tuning tab allows for adjustments to gain, loudness, and comfort issues after First Fit.

• Master Gain: Adjusts overall gain for all frequencies and input levels.
• Soft Sounds: Adjusts the 50 dB curve.
• Medium Sounds: Adjusts the 65 dB curve.
• Loud Sounds: Adjusts the 80 dB curve.
• Speech: Increases/decreases gain for speech intelligibility.
• Too Sharp: Increases low and mid frequencies, decreases high frequencies.
• Too Muffled: Decreases low and mid frequencies, increases high frequencies.

Fine Tuning - Noise Reduction / Microphone

Noise Reduction

Noise reduction is primarily controlled by Soundpro 2. It is recommended to use Automatic Noise Reduction in program 1 (Automatic).

1. To modify Noise Reduction, uncheck the 'Automatic Noise Reduction' box (unchecked by default in programs 2 through 6).
2. Click on the Manual Noise Reduction tab.
3. Change settings from Min to Med or Max as preferred.
4. If the wearer prefers no noise management, uncheck the box to the left of the option.

   [Images: Connexx software's Noise Reduction interface, showing options for Automatic and Manual Noise Reduction, Noise Management, Wind Noise Cancellation, Sound Smoothing, and AutoEcho Reducer.]

It is not recommended to deactivate Noise Management, Wind Noise Cancellation, Sound Smoothing, or AutoEcho Reducer.

Microphones

Microphones are controlled by Soundpro 2.0 in program 1. To adjust microphones in programs 2 through 6:

1. Engage the program where you want to change microphone settings.
2. Click on a microphone option. Options vary by program.

   [Images: Connexx software's Microphone settings interface, showing options for microphone management and directionality.]

Intelligent Feedback Preventer

Feedback Reduction Strategies

Several methods are available to adjust feedback conditions.

Strategy 1: Intelligent Feedback Preventer

1. This feature is set to 'Fast' by default for maximum effect. It can be changed to 'Slow' for specialized sound processing, such as for musicians.

   [Image: Connexx software showing the Intelligent Feedback Preventer settings, including a 'slow' and 'fast' toggle.]

Strategy 2: Perform a Critical Gain Measurement and Optimize

Insert hearing aids into the wearer's ears.

1. Click on the Critical Gain Tab in the First Fit screen.
2. Click on Start Measurement.

   [Image: Connexx software displaying the Critical Gain Measurement screen with a 'Start Measurement' button.]

3. The system optimizes the Automatic program. Other programs may also be optimized. Optimization might affect gain; if there's significant overlay with the critical gain area, consider changing dome/mold type and recalculating the fit.
4. Repeat for the other ear.

If current settings are prone to feedback, optimization might affect hearing aid response. In such cases, adjust Acoustical parameters (physical and software) and/or receiver power.

Bandwidth Features

Bandwidth Features adjust output frequencies, moving amplification from frequencies with no benefit to those where it is beneficial. This feature is automatically enabled during First Fit if audiological conditions are met.

To modify the response:

1. Click 'Frequency from' to select the lowest frequency to be moved, then select a new value from the dropdown menu.
2. Click 'to' to select the highest frequency for output, then select a new value from the dropdown menu. (Example: 12 KHz moved to 8 KHz).
3. To turn this feature off, uncheck the box labeled 'Enable Bandwidth Compression'.

   [Image: Connexx software's Bandwidth Features interface, showing controls to set frequency ranges and an option to enable/disable bandwidth compression.]

Adjusting Audio Streaming

The wearer can stream audio from program 1, Automatic, without additional programs. Streaming is optimized based on the coupling selected.

To adjust the streaming signal:

1. Select the signal to modify: BT - Audio for iPhone, Android or Smart Mic, or BT - TV for Smart Transmitter 2.4.
2. Check Streaming Offsets.
3. Select the number of handles for desired detail level when modifying the streaming signal.
4. Adjust using the up and down arrows.
5. Select 'Auto volume' to allow streaming volume to change based on ambient noise level (checked by default).
6. Select 'Mix with microphone' to allow the wearer to hear both the streaming signal and microphone signal simultaneously (checked by default).
7. Use the slider to determine the loudness of the microphone signal as a percentage of the streaming signal loudness. (Example: microphone loudness is 30% of streaming signal).

   [Images: Connexx software's Audio Streaming interface, showing controls for adjusting signal levels, auto volume, microphone mix, and microphone loudness percentage.]

Configuring User Controls

   • Use current gain as end-point: Fit to target and reduce gain to start the process of returning to target.
   • Fitting formula related: Fit to an experience or acclimatization level within the fitting formula and increase to a higher level.
4. Smart Acclimatization: Activate to adjust duration time based on wearer's volume usage.
5. Offset: Choose a system offset (Flat, Speech, High Frequency), custom values, or an Acclimatization Target to change the hearing aids' response.
6. Select the Duration period for the acclimatization process.
7. Click the Start button to initiate the acclimatization process.
