Introduction
The ADHEAR system is s an effortless treatment option for people with conductive hearing loss or single-sided deafness. In both application cases, ADHEAR uses the concept of bone conduction to transfer sound via the skull bones to a normally functioning cochlea.The system is delivered pre-configured with four programs which are optimised for the needs of ADHEAR users and the transmission of sound via bone conduction.The purpose of the optional ADHEAR Configuration Software is mainly to optimise the standard configuration of the ADHEAR Audio Processor for the user‘s convenience or for specific needs (e.g. for young children). It can also be used to modify device settings in cases where the pre-configuration does not meet the needs of a specific user.The aim of this configuration guide is to provide you with an overview of the most important functions of the ADHEAR Configuration Software. These functions will help your clients get the best out of their revolutionary ADHEAR Bone Conduction Hearing System.

NOTE When using the ADHEAR Configuration Software within a NOAH framework, clients are managed through NOAH and the Client‘s Base Data screen will not be accessible.
After selecting the existing client or new client option, the Client‘s Base Data will open in a new window.You can access the client‘s base data at any time while using the software by clicking on the symbol in the menu bar.
Figure 3: Client‘s Base Data
Client DataYou can enter the client‘s data in the upper part of this window. It is mandatory to enter the last name in the database, however, we suggest to enter at least first name, last name and date of birth. This will facilitate client identification and search in the client list.
Ear Specific InformationIn the lower section of this window you can enter the client‘s ear specific information. The audiogram allows for entering (masked) BC and AC values and UCL for both ears. You can also select whether the client is a binaural user or has single-sided deafness.We also suggest entering the Serial Number (No) of the ADHEAR Audio Processor used for the respective ear(s), in the corresponding field.
Client’s Base Data
Important Note
All data entered in this window is for information only. There will be no adjustments made to the device based on e.g. values entered in the audiogram or the selection of single-sided deafness in this client’s base data.

Once you have finished the preparations, you can modify the device configuration using the Configure the Selected Device symbol on the menu bar.The system will now detect whether an ADHEAR Audio Processor is connected via the CS44 configuration cable to a programming interface, e.g. a HIPRO Box.If no device is detected, the ADHEAR Configuration Software will automatically enter the simulation mode. In this case, the word Simulation is displayed above the graph showing the output characteristics of the device.
Figure 5: Configure the Selected Device
NOTE If two devices for bilateral usage have been selected, both configurable audio processors will be displayed side by side in this window. For a better overview, this configuration guide will only show configuration of a single device.

Important Note
The Enable/Disable Programs option may be especially useful when the ADHEAR is used by young children. The program change button is disabled when only one program is configured, ensuring that the ADHEAR Audio Processor remains in the default setting.
To modify the pre-configured programs, click on the Programs button.
Enable/Disable ProgramsChoose the number of programs you want to activate in the ADHEAR Audio Processor (1 to 6 programs) and confirm your selection by clicking Apply & Close.

In this tab you can make basic adjustments to the programs and the device.
Figure 10: Basics
VC EnableThe volume control (VC) on the device can be de-/activated by ticking the VC Enable box. The VC Startup option allows for adjustment of the default setting of the volume control, valid for all programs. The standard setting is -4dB from the maximum gain.
Feedback ReductionThe feedback cancellation algorithm can be selected and deselected here for each individual program.
Input ModeIn this section you can select the input mode and the microphone option for each program. The following options are available: - Full Automatic: Sound environment classifier
enables omnidirectional or adaptive directional microphones depending on the situation
- Adaptive Directional: Directionality to the front with adaptive noise suppression in direction of the loudest source of noise.
- Directional: Directionality to the front with stationary noise suppression
- Omnidirectional - Audio Input (DAI): 100% input via the direct
audio input, microphones muted - Mic+DAI: 50% omnidirectional microphone
input, 50% input via direct audio input
Important Note
The VC Enable option may be especially useful when the ADHEAR is used by young children. Disabling the volume control will make sure that the ADHEAR Audio Processor remains in the default setting.

In the Equalizer tab you can change the gain of the 8 channels of the ADHEAR Audio Processor individually within a range from 0 dB to -24 dB. The master gain of the device can be adjusted by selecting Σ. Use the slider at the very left (below Σ) to adjust all channels at the same time.
Figure 11: Equalizer
Equalizer
CONFIGURATION
12
Within this tab, you can adjust the input/output characteristics of the system for the individual programs. The following adjustments can be made in 8 individual channels - Lower Threshold: Adjust Threshold for Low Level Gain setting - Upper Threshold: Adjust Threshold for High Level Gain setting - Low Level Gain: Adjust gain for soft input sounds - High Level Gain: Adjust gain for loud input sounds - Squelch Ratio: Adjust squelch ratio - Squelch Threshold: Adjust squelch kneepoint - Crossovers: Adjust frequency ranges of the channels
The compression is based on the Lower/Upper Thresholds and corresponding Gains. The squelch region below the squelch threshold is a low input level expansion (squelch ratio).
Compression (Advanced Option)
Important Note
The ADHEAR Audio Processor is pre-set and optimised for use in cases of conductive hearing loss and single-sided deafness. In both cases the system is stimulating normally functioning inner ears and it is not anticipated that adjustments of compression settings will vastly increase the client‘s benefit. Modifications of compression settings should therefore be limited to cases where there seems to be no alternative as extensive modifications could lead to deterioration of sound perception. The device can be restored to default settings as described on page 9 of this configuration guide.

Datalog
NOTEThis visualisation tool is only available in the English language.
Figure 15: DataLog
Data logging is available for the ADHEAR system and a visualisation tool is provided with the configuration software. Please note that the coding for the individual programs in the audio processor is as follows: Memory A = Program 1, Memory B = Program 2, etc…With this tool, the period of device use and the selection of the programs can be analysed. More detailed information about the analysis of the sound environments based on the classifier in default Program 1 are also available within the Environment tab. Data can be stored and retrieved via the Save to File and Load from File options.
NOTE To reset the data logging file in the ADHEAR Audio Processor, select Clear Log within Advanced Features
Noise Reduction You can adjust the noise reduction setting of each individual program from 0 dB (off) to 12 dB. Noise reduction settings are different in the individual pre-set programs, for example, with a DAI input, mode environmental noise reduction is not active.
AGCOThe slider for setting the automatic gain control – output (AGCO) is available to decrease the maximum volume of the system by up to -30dB.
Advanced Features
Important Note
It is highly unlikely that ADHEAR users will perceive sounds as disturbingly loud which would require a reduction of the maximum volume. We therefore strongly recommend not to reduce the output of the system with the AGCO control.
