Soundpro 3.0

Customizing Soundpro 3.0

Soundpro Mode

The default setting, Balanced Focus, should be maintained during First Fit. If changes are required during follow up visits, proceed as follows:

1. To shift the focus toward environmental sounds, move the slider to the left. You have 3 steps available. This classification will more often choose microphone modes with less directionality. This is more beneficial for people that required full processing support only in very demanding situations.
2. To increase the focus on speech components, move the slider to the right. You have 3 steps available. This classification will more often choose microphone modes with more directionality and stronger noise reduction. This is more beneficial for people that face challenges to understand speech even at low noise levels.

Manual Offsets

Changing these offsets will affect all acoustic environments where that component is present. i.e. Noise as part of Speech in Noise or Noise as part of Background Noise, etc.

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

These changes are made in 1 dB steps.

Manual Offsets - Bluetooth

You may adjust the Bluetooth audio streaming response in Soundpro 3.0. The changes will carry over to the Audio Streaming tab under Fine Tuning.

My Voice 2.0

Programming My Voice 2.0

What is My Voice 2.0?

Acceptance of hearing aids relies heavily on the client's perception of their own voice. For example, clients often find their own voice too loud. My Voice 2.0 detects when the client is speaking and improves the perception of their own voice.

Programming Steps:

1. Instruct the patient to wear the hearing aids. Provide the wearer the instructions displayed on screen and click Go to training.
2. Follow the instructions on screen and click Next.
3. Instruct the wearer to start counting after hearing a beep. If the hearing loss is such that the wearer would not hear the tone clearly, instruct them that they will start counting when you point at them. Click Start training, count to 5 and then point at the wearer.
4. When the training is complete, click Close.

My Voice defaults to Med (medium) which works for the majority of wearers. In case the wearer feels that their voice is still too loud, you may move it to Max. If the wearer states that their voice sounds flat or weak, you may move it to Min.

Automatic Acclimatization

Enabling Automatic Acclimatization

First Fit to target for best audibility, perform REM and, if required, activate Automatic Acclimatization to reduce gain for user comfort. The hearing aids will gradually increase gain to comfortably achieve the prescribed audibility target.

1. Click on Automatic Optimization [1]
2. Click on Automatic Acclimatization [2]
3. Select a Strategy:
   • a. Use current gain as start-point: start at current settings and increase to final preferred gain settings. This method requires REM at the beginning and end of the process to ensure proper amplification.
   • b. Use current gain as end-point: fit to target within ISA tolerances, perform REM, and reduce gain to start the process of returning to target. This is our recommended strategy as it works best with REM, requiring the aids to be measured only at the beginning of the process.
   • c. Fitting formula related: fit to an experience or acclimatization level within the fitting formula and increase to a higher level of the fitting formula. You may have to perform another REM at the end of the process.
4. Smart Acclimatization: activate to adjust the length of the process based on wearers' volume control usage.
5. Settings: you may choose the software determined system offsets, the manual offsets, or combine system and manual offsets.
   • a. System offsets: Flat, Speech or High Frequency
   • b. Manual offset: 1 dB step gain changes
   • c. Acclimatization Target (if selecting Fitting Formula Related) to change the hearing aids' response.
6. Select the Duration period for the acclimatization process.
   • a. 1 or 2 weeks is recommended for conductive or mixed losses.
   • b. 4 weeks or 2 months is recommended for sensorineural losses.
   • c. 6 months is recommended for recruitment.
7. Click the Start button [Start] to initiate the acclimatization process.

NOTE: You will need to stop the process to make changes that affect gain or compression, change couplers or receivers, perform My Voice 2.0, or add programs. If you need to stop the process you can:

• Press the Stop button [Stop] to end the process. The hearing aids will remain at the level they have reached at that time. This will differ from the values you measured with REM.
• Press the Reset button [Reset] to stop the process and return the hearing aids back to the settings measured right before applying offsets. These will be the same values you measured with REM.

Basic Tuning

Use the Basic Tuning tab to make adjustments for gain, loudness and comfort issues after First Fit.

• Master Gain adjusts overall gain for all frequencies and input levels. Note: the number indicates an average of gain across all channels.
• 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 and decreases high frequencies.
• Too Muffled decreases low and mid and increases high frequencies.

Fine Tuning - Amplification Settings

Fine Tuning

Fine Tuning is divided in multiple tabs to make detailed adjustments to most features of the hearing aids. It is divided in:

• Amplification
• Noise Reduction/Microphone
• Bandwidth Features
• Precision REM
• Fitting Assistant
• Audio Streaming/Bluetooth

Compression

Use this tab to control gain and compression.

1. Click on a handle number to change the number of channels to modify.
2. Click on a number to select a channel and a loudness level.
3. Click on a number and drag sideways to adjust several channels together. This is called "lasso" function and it is also available for the Frequency details and MPO tabs under Fine Tuning - Amplification.
4. Click on the gray button on at the top of the column to adjust all loudness levels for that channel.
5. Click on the gray button on the upper left to adjust all channels.
6. Click on L150, L165 or L180 to select and adjust that loudness level.
7. Use the Outside arrows ⬆️⬇️ to adjust in 3 dB steps.
8. Use the inward arrows ⬆️⬇️ to adjust in 1 dB steps.

Optional: Adjusting Gain Via Curve Display Manipulation

Changing the View in Connexx

To quickly match REM targets using visual cues, you may change the view in Connexx from Gain to Output. At that point, the response curve will look similar to the one viewed in the REM user interface.

Singular Loudness Level Change

To change the response for only one curve, place the mouse pointer on the curve and the channel you want to modify until it turns into a double arrow. In the image to the right, you are changing the channel that covers from slightly below 3 KHz to slightly below 4 KHz at the 65 dB level.

Multiple Loudness Levels Change

To change the response for multiple curves all three loudness levels simultaneously, place the mouse pointer on the channel you want to modify until it turns into a hand. In the image to the right, you are changing frequencies around 2 KHz for all three loudness levels.

This feature may be used in Fine Tuning Sound & Loudness, in the Frequency Shaping, Compression, MPO and Kneepoints and Ratios (when using NAL/NL2) tabs. It may also be using in the Basic Tuning tab.

Please note that the output view will remain in place until you change it back to gain. We recommend returning it to Gain view once finished for ease of use of other dispensers.

[Image: Connexx interface showing Gain vs. Output views and examples of singular and multiple loudness level adjustments on frequency response curves.]

Fine Tuning - Noise Reduction / Microphone

Noise Reduction

Noise reduction is primarily controlled by Soundpro 3.0. It is recommended to leave it on 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 from Min to Med or Max as preferred.
4. If the wearer prefers not to have noise management, uncheck the box to the left of the option to turn off.

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

Microphones

Microphones are completely controlled by Soundpro 3.0 in program 1. To adjust microphones in programs 2 through 6:

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

Intelligent Feedback Preventer

Feedback Reduction Strategies

If feedback conditions exist there are several ways to make adjustments.

Strategy 1

Intelligent Feedback Preventer

1. This feature is on Fast by default for maximum. You may change from Fast (default) to Slow for people that require specialized sound processing, such as musicians.

Strategy 2

Perform a Critical Gain Measurement and Optimize

Insert hearing aids into the wearer's ears.

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

The system will optimize the Automatic program. As other programs are added, they will also be optimized if required. Optimizing may or may not affect the gain of the hearing aid. If there is a significant overlay of the critical gain area and the hearing aid response, it is advisable to consider changing to a different style of dome, sleeve or custom mold and recalculate the fit.

1. Repeat for the other ear.

In situations where the current settings are prone to feedback, optimization may affect the hearing aid's response to the point of preventing from reaching targets on REM. In this situation, change your Acoustical parameters (both physically and in the software) and/or receiver power.
