Audio Service lexicon

In the following area, you will find all of the information about technical terms and product features.

Section A

Acclimatic refers to the automatic amplification adjustment within a defined time period. The acclimatization objective and duration are adjusted individually for the end customer. This is particularly good for helping new users to get used to the hearing systems gradually.

Following the First Fit initial adjustment of the hearing systems, there are 3 options for using Acclimatic:

  1. Use current gain as starting point: fine tuning of the hearing systems with the goal of achieving good spontaneous acceptance. After the first few days of getting used to the systems, select the acclimatization objective and duration and test the target setting. Then activate Acclimatic.
  2. Use current gain as endpoint: fine tuning of the hearing systems with the desired final setting. Select the acclimatization objective and duration. Then push the current gain as endpoint button.The amplification is reduced in accordance with the selection made under Objective. Then start Acclimatic.
  3. Fitting-formula-related: acclimatization from New user to Experienced user or from low to selectable high acclimatization level, depending on the fitting formula. With the TL 16 – 8 hearing systems, Connexx allows for individual selection of the acclimatization objective in addition to the pre-defined fitting objectives.
Intelligent Acclimatic, in all hearing systems of TL 16 and 12 with volume control. The volume can be manually adjusted by accelerating or decelerating the automatic acclimatization process.
This smart technology automatically suppresses unpleasant wind noise and therefore ensures a more comfortable hearing experience, particularly outdoors. In this case, if necessary, the directional microphone is switched to omni-directional and the low-frequency amplification is reduced to below 1 kHz.
The Anti-Feedback system automatically detects feedback and cancels it quickly and effectively. The intensity of the feedback cancellation can be adjusted in Connexx.
AudioDirSelect is useful for a hearing system wearer with individual wishes and needs (if the automatic mode does not provide the desired result).
AudioDirSelect makes it possible to select the direction of the focus manually via an app (individual direction; tap to select desired direction). In this way, a directional focus that may have been selected automatically can be overwritten at any time.

AudioFix is the cosmetic and practical solution for fitting with AudioFix Tube and open shell ear mold (Audio Shell).
The AudioFix clamp system allows the variable-length tube with the Audio Shell to be individually aligned with the ear and fixed in place (see also Audio Shell).
Thanks to the intelligent, reusable clamping sleeve, the tube can be changed rapidly at any time.


AudioFocus 360 is also able to focus automatically directly to the sides, if the dominant speech comes from the side. This means that, regardless of the position of the speaker, the loudest speaker is focused on directly and background noises from other directions are suppressed.
The previous Speech 360 mode only works omni-directionally when recognizing a speaker on the side.

AudioLink is the high-performance data connection between the left and the right hearing system. AudioLink is the prerequisite for the AudioTronic multi-microphone system.
AudioLink enables genuine audio signals to be transmitted between the hearing systems by evaluating up to 4 microphones. This process creates a detailed variable image of the acoustic environment and emulates the natural hearing process.

The customized open BTE solution for all XS, DUO, and many P hearing systems. The AudioFix clamping system is designed so that the variable-length tube with the Audio Shell can be aligned perfectly on the ear and individually secured in place.
Compared to the Open Tip, the Audio Shell offers an extremely large degree of openness and individual positioning comfort (see also AudioFix).

Comprehension of speech in a noisy situation is particularly acoustically challenging – even for those with normal hearing. A classic example of this is the cocktail party scenario.
The AudioSpot mode is designed specifically for this hearing situation. AudioSpot uses a small frontal focus of up to 45 degrees, which is aligned toward the person speaking and standing in front of the person wearing the hearing system. In addition, the background noise outside this focus is effectively suppressed.
The width of the directional level is selected automatically.

Automatic and adaptive directional characteristics of the AudioTronic multi-microphone system in custom hearing systems with one microphone. The directionality is generated by AudioLink with its facility for evaluating the left and right audio signals together. This is complemented by the natural directional effect of the human ear.

AudioTronic stands for multi-microphone technology with switchable operating modes.
Omni-directional: the microphone picks up sound from all directions.
Panorama: the directional characteristics recreate the natural attributes of the human ear. Deep frequencies are processed
omni-directionally and high frequencies are processed with directional characteristics.
Directional/directional static: the microphone picks up sound from in front.
Adaptive: operating mode in which movable sources of background noise are subdued based on direction.
Automatic: hearing systems automatically switch between omni-directional, panorama and selected directional operating mode, also binaurally synchronously in the case of wireless functionality.
Speech 360: the microphone focuses on the direction from which speech is coming in a 360° range.
AudioFocus 360: automatically focuses on the direction from which speech is coming in a 360° range. Compared to Speech 360, an additional lateral directional effect is created.
AudioSpot: concentrated frontal focus of the directional effect. It significantly reduces the hearing effort in a noisy environment. The hearing angle automatically narrows in noisy situations to around 20 degrees to the right and left of center.

Depending on the hearing situation identified by the classifier, the automatic control of the noise manager as well as AudioTronic and Comformatic is activated.

Section C

The classifier automatically recognizes up to 6 different hearing situations:

  • Speech in Quiet
  • Speech in Noise
  • Noise
  • Music
  • Car
  • Quiet
Individual ear mold for the Audio Service RIC hearing systems. Easy and secure click connection to connect to external receivers. Better individual fit in the ear: no slipping or falling out during movement. Defined acoustic positioning: The positioning in the auditory canal and thus the volume and frequency spectrum can always be reproduced.
The CLIC MOULD 2.0 is fitted with the small HF 4 Black wax guard as standard. The Clic Ball of the external receiver ensures optimum hold and allows maximum movement.
The CLIC MOULD is available in Open and Power versions. Even for wearers who have a high degree of hearing loss or prefer a closed system, CLIC MOULD Power offers a cosmetically appealing solution.
The CLIC MOULD Open is compatible with the AudioFix system.
Standard ear mold for immediate fitting of RIC hearing systems. Available as Click Dome Open, Semi-open, Closed or Double. The Clic Ball of the external receiver can be rotated after it has been clicked into the dome. This ensures excellent wearing comfort and a perfect fit in the ear.
Standard ear mold for immediate fitting of RIC and quiX hearing systems. The flexible, soft Click Sleeve adapts perfectly to the geometry of the auditory canal and enables a secure fit in the ear (especially in a large auditory canal). The standard ear mold is available in sizes XS, S, M and L, in open (vented) and closed versions for each size.

The easy-to-clean ComforClean coating prevents soiling of all kinds – cerumen, sweat and dust – from sticking to the surface and causes soiling to roll more easily off the surface of the hearing system or the ear mold.
This protects the hearing system housing from aggressive dirt particles and the roll-off effect makes cleaning especially easy.

Comformatic stands for an automatic, situational frequency response adaptation.
By means of the classifier, adaptation based on the situation and also frequency response configuration take place. Thus within the hearing program, the characteristics are changed and as a result, the tone of the hearing system is optimized, along with the noise parameters. The result is enhanced sound quality and clearer speech in every hearing situation.
In the models of Tech Level 16 and 12, the individual setting of the mode of action of the frequency response configuration offers even more variability.
The ComforMed finish utilizes the fungicidal and biocidal effect of pure silver. This patented finish, which contains silver (protects against bacteria and germs), significantly enhances the wearing comfort of custom model hearing systems. This special coating also promotes natural climatic conditions in the auditory canal, thus preserving the ear’s natural balance. Optional for all custom hearing systems and ear molds, and a standard feature of TL 16 custom models.

Section D

The electronic “diary” for effective and customized fine-tuning. This technology continuously logs and analyzes various parameters and data while the hearing system is worn: hearing environment, frequency with which the programs are used, wearing time, change of the volume in the individual programs with display of the corresponding dB level.
Supplemented by the customer’s own input, this information enables exact fine-tuning. It makes situations that are difficult to describe easier to analyze and enables any problems to be alleviated with precision.
Direct Audio Streaming allows outstanding, customized sound quality to be achieved. Additional devices are no longer required. Bluetooth® is the established standard for wireless data transfer over short distances in the 2.4 GHz range. The low-energy version BLE works with shorter connection set-up times and short pauses between the transmission cycles. However, it is not possible to use it to transfer audio files. For this reason, Apple has been employing its own specialized Bluetooth® protocol since the iPhone 5 (iOS 9.3). This allows audio signals to be streamed both energy-efficiently and in high quality. The same protocol is also employed in G5. The transfer is always effected in stereo quality.

Section E

Pleasant communication in an echoing room. Communication in an echoing room – for example, in a hallway or gym – is a challenge for the hearing system wearer since the direct sound of the conversation partner is superimposed with reflections. This reduces speech discrimination and makes it harder to hear. The special hearing program detects the level difference between direct sound and reflected sound and thus reduces echo effects and reverberations. In addition, the directional mode is activated.

Section H

The HF 3 Black and the smaller HF 4 Black wax guards reliably prevent cerumen, dirt, and moisture from entering the hearing system via the receiver opening. This effectively extends the overall service life of the hearing system.
The features of the Audio Service wax guards are impressive:

  • Practical and easy to use
  • Self-cleaning high-tech gauze
  • Repels moisture, dirt, and cerumen
  • Robust and maintenance-free
  • Available in different packaging units
  • Acoustically transparent and distortion-free up to 90% soiling
  • In the case of extensive soiling, muffling indicates the need to change the guard
  • The service life of the hearing systems is extended
All filter systems come in red and blue in a practical dispenser roll. The wax guards therefore also make it easy to distinguish between left and right hearing systems.
With HiFi functionality, the signal bandwidth for the microphone programs has been extended to 10 kHz. Transmission of the high-frequency parts of the signals has a positive impact on sound quality. Hearing is more natural, which particularly enhances the perception of natural sounds and music. With HiFi, wearers can experience multi-faceted, complex and full sound. Speech clarity is improved thanks to transmission of the speech-relevant harmonic waves and the accentuation of consonants. Comprehension in complex background noise situations becomes a lot easier and localization is improved.

The HighRes Comformatic analyzes the acoustic environment moe thoroughly than ever before. And goes beyond. The motion sensor adds  a completely new dimension to the definition of specific hearing scenarios. The result is: a more individualized hearing experience and better sound quality than ever.

Section I

IP (Ingress Protection) is an international standard for protection against foreign bodies (e.g., dust) and water. The first number relates to protection from dust and the second to protection from water. Certification is carried out by independent institutes that test and evaluate the products. The result describes the state of the device after exposure to the test condition in question. The codes achieved indicate the level of protection that the device in question attained.

Section L

Well informed in any situation: your customers receive clear feedback when the controls on the hearing system are pressed, depending on the ambient noise level.

Section M

MEMS microphones (microelectromechanical systems) are robust and thus highly resistant to environmental influences, temperature fluctuations and aging. As a result, the directional bias during use in the multi-microphone systems remains constant and the hearing systems are thus equally high-performance. In addition, MEMS microphones do not use much energy, and this in turn has a positive effect on battery life. MEMS microphones are used in various hearing systems of the G4 and G5 generations.
Comfortable hearing, even on the move. The G5 hearing system integrates the smartphone’s motion information in the situation analysis, and the auto-situation adaption then automatically selects an appropriate signal processing strategy.
Microsafe is the world’s first microphone filter for custom hearing systems that effectively reduces wind noise right where it originates: directly in the ear. The integrated filter, which can be changed from outside, systematically blocks out disruptive wind noise without impairing the speech signals. It also protects against soiling. The result: hearing comfort is enhanced significantly, there is less downtime, and fewer repairs are needed.
With a diameter of just 1.85 millimeters, Microsafe is much smaller than the wax guards. Standard with all semi-modular custom hearing systems.
Broad range of vent geometries for individual optimal solutions in custom models; see also vent options.
Experience the ultimate enjoyment of music. In comparison to speech signals, music signals have an expanded frequency and dynamic range. When listening to music, hearing system wearers often miss sound nuances and dynamic range which can lead to distortion in loud passages. Based on these findings, MusicSelect was developed: special signal processing for the demanding music lover.

Section N

The noise manager is based on the classifier. Depending on the situation identified, noise reduction, Selectronic, impulse suppressor or wind noise cancellation are automatically activated. This ensures unhindered quality of hearing at all times.
If the noise manager is switched off, the noise reduction can be manually adjusted.

Section O

Occlumatic can help hearing system wearers to perceive their own voice more naturally and get used to hearing systems more simply and easily. During the fitting, the G5 chip learns to recognize the hearing system wearer’s voice. This sound pattern is stored in the hearing system and employed in real-time to analyze the microphone signals. As soon the hearing system wearer’s voice is identified, a specially calibrated signal processing strategy is employed. The general amplification is not affected.
Thin tube with standard ear mold (tip). Quick-start option for open-fitting systems. For rapid fitting and immediate hearing success.
Ideal preparation for fitting an individual hearing system.

Section Q

Standard ear mold for immediate fitting of quiX hearing systems. The quiX MOULD is an open, hard ear mold which ensures a good, secure fit in the ear and provides good occlusion. Available in sizes S, M and L.

Section R

The nylon or carbon removal line (depending on the model) makes it easy to remove a custom hearing system from the ear.
An exchangeable filter in the external receivers protects them from soiling. In combination with the HF 4 Black in the CLIC MOULD or the filter in the Click Dome, the external receivers are doubly protected.

Section S

Selectronic is an extension of the noise manager and combines fast noise reduction with effective directional microphone technology. Selectronic suppresses stationary and fluctuating background noise. In particularly challenging background noise situations (such as at a cocktail party) it improves ease of hearing and reduces the effort required to hear.
The selective frequency compression compresses relatively high-frequency information in a deeper frequency range. As a result, high-frequency proportions of speech and sounds are selectively brought into the audible range. The vocal information and quality are essentially retained. Frequency compression is advantageous for persons with advanced hearing loss, but other types of hearing loss, such as ski-slope hearing loss, can also benefit from this technology.
Sound Upgrade represents artificially expanded sound. This has a positive effect on the sound of the hearing systems, particularly in wireless audio streaming mode.
Improved spatial awareness without any compromises on directionality. SpatialSpot expands your customers’ auditive radius by
functioning dynamically with a frontal focus and blending in spatial components at the same time. Hearing system wearers can concentrate on the conversation, but still react to additional acoustic signals.

Section T

The modern TRC S compression concept works with two variable compression levels. The knee points are intelligently defined by the First Fit. As a result, the adjustment of the amplification curves for low, medium, and loud input levels can be very easily made with the compression ratio (CR) and the amplification (GC). The adjustment for the applicable input level is thus completely independent of the amplification setting for other input levels.
TRC S is particularly suitable for contemporary fitting philosophies (e.g., percentile analysis).
When using the traditional fitting formulas (NAL-NL2, DSL v5) the compression parameters can be manually accessed.

Section V

Ideally, the vent of custom hearing systems needs to be big enough to prevent occlusion while the system itself has to be kept small. Good sound quality is also essential. The Pro-Vent is ideal for these requirements. It is available in two versions:

  • EquiVent
    The aim is an extremely small custom hearing system that delivers acoustically equivalent performance to a round vent (AEV - acoustically equivalent vent).
  • ComforVent
    The aim is to find the best balance between freedom from occlusion and a pleasant sound (AOV – acoustically optimized vent).

Section W

Hearing systems support wireless communication. This is the prerequisite for the following functions:

  • Binaural synchronization
  • Data comparison of operating elements and their functions
  • Data comparison of various features
  • AudioLink
  • Wireless audio input / Bluetooth remote control (TL 4-16)
  • Remote control (TL 4 – 16)
