Beltone technologies

The core technology of Beltone’s products aims at creating the most natural hearing experience for the hearing impaired. With a high number of adaptive and automatic features you can easily tailor a Beltone hearing aid to your customers’ individual needs. Beltone hearing aids very precisely restore audibility for the hearing impaired by combining the fast-acting digital sound processing system and unique curvilinear Wide Dynamic Range Compressor (WDRC).  

Explore the core features behind the Beltone Technologies:


Smooth and precise frequency response

The Rapid17™ digital sound processing system emulates the structure of the critical bands in the human cochlea to allow precise frequency shaping and effective compensation for any type of hearing loss. The Rapid system is also available in versions of 9, 6 and 3 channels.   

Spatial Directionality 134X194

Spatial Directionality

Spatial Directionality is a binaural fitting strategy that allows one hearing instrument to be set in directional mode, while the other is set in an omni directional mode for environmental monitoring. The benefit is a more realistic listening experience. 


Optimized hearing range

Beltone’s unique Curvilinear WDRC approximates the loudness growth of a healthy cochlea.

Through the three fitting curves, 50 dB, 70 dB and 90 dB, fine-tuning adjustments can be made for various input levels to ensure that sounds are audible and comfortable. In addition, the MPO works individually in each channel to prevent amplification above the uncomfortable level (UCL).Your customers benefit from:
  • More natural sound experiences
  • Tailored gain levels for optimal sound perception
  • Protection from sudden loud sounds
  • Optimal use of the hearing range

Effective feedback management

The feedback management system is a very important feature for providing good sound quality in a hearing instrument. With an effective feedback management system you will be able to provide the gain, clarity and comfort that is needed for a successful fitting.

As an amplified signal leaks out of the ear and is picked up by the hearing aid microphone, a feedback loop is generated and annoying feedback is heard. Beltone’s Improved Adaptive Active Feedback Cancellation (AFC) produces a signal (grey wave) that is equal in frequency and amplitude but opposite in phase to the feedback signal (blue line). The result is a cancellation of the whistling loop.

Beltone's Feedback Eraser with WhistleStop provides improved feedback path modeling and more added stable gain than any other feedback system on the market today.


Listening becomes more pleasant

The Beltone Sound Cleaner and new Sound Cleaner Pro are spectral subtraction-based noise reduction systems. They operate in all 17 compression channels and analyze the incoming signal at 1 millisecond intervals to determine whether speech or noise is present. The noise detector estimates the noise spectrum in the pauses of speech and subtracts that spectrum from the succeeding input. Sound Cleaner Pro builds upon the Sound Cleaner foundation and not only reduces unwanted noise from the signal, but does so without appreciably reducing the speech portion of the signal.


Effective wind noise suppression

Wind Noise Suppression detects and suppresses noise generated by wind, including mild breeze.  This feature can be set to Mild (-10 dB), Moderate (-15 dB) or Strong (-20 dB).  


Enhanced speech understanding

Smart Beam Steering is part of the Improved Adaptive Directionality feature that seeks to enhance speech understanding. Smart Beam Steering automatically adapts to the optimal width of the directional beam. The hearing aid wearer will experience continued maximum focus on the signal of interest - even in constantly changing environments.


For optimal settings

The Beltone Satisfaction Journal gathers data on how the customer uses the hearing aid. During follow-up fittings, the Journal information can be applied when adjusting the settings of the hearing aid. This data logging feature also provides more accurate information when counseling the client.
Beltone Satisfy helps your customers to adapt smoothly to their new hearing aids. The feature allows the customer’s preferred amplification settings to be implemented at the initial fitting and then gradually increased or decreased to the optimal settings.

The Beltone fitting formula: BAFA

Beltone’s fitting prescription formula, known as Beltone Adaptive Fitting Algorithm (BAFA), is an effective starting point for fitting all Beltone hearing instruments. BAFA combines loudness normalization and loudness equalization. The result is an initial fit with appropriate gain and comfort settings, while at the same time considering personal preference in judging satisfactory hearing instrument gain.
