Product Overview

The TW1-BTE-P is an 8-channel BTE hearing aid with programmable digital processing, developed for hearing-care distributors, clinics, importers, retailers and private-label partners. It combines essential professional fitting functions with Bluetooth-supported app control, giving B2B partners a clearly positioned foundational model for a structured digital BTE product range.

Multichannel compression, feedback cancellation, noise reduction, directional processing and four selectable programs create a practical platform for professional fitting, follow-up adjustment and service-led distribution.

8-Channel BTE Hearing Aid Fitting Architecture

Independent Compression and Amplification Control

The TW1-BTE-P provides 8 independent compression and amplification channels, allowing the fitting professional to shape gain and compression behavior across the frequency range. This provides more control than broad, non-specific amplification adjustment.

16 Independently Adjustable Bands

The 16 adjustable bands provide additional frequency-specific control within the fitting process. While the compression channels organize amplification behavior, the adjustable bands allow finer shaping of the programmed response. Together, the 8-channel and 16-band configuration gives fitting teams a practical balance between adjustment capability and operational simplicity.

32 DSP Processing Channels

Its 32 DSP channels support compression, feedback, noise-management and directional functions while providing a clear specification for positioning the foundational model in the three-product series.

Intelligent Signal Processing

ACOD3101 Multi-Core DSP

The ACOD3101 intelligent multi-core DSP provides the processing foundation for amplification, compression, noise management, directional processing and fitting control.

ERAC 1.0 Dual-Knee Compression

ERAC 1.0 context-analysis-based intelligent multi-compression technology uses a dual-knee design to manage amplification across different input levels. The fitting response can therefore be organized for softer, medium and stronger incoming sounds through a more controlled compression structure. The technology complements professional assessment by giving the fitter an adjustable and repeatable processing foundation.

Feedback, Noise and Directional Management

• AFC 2.0 Feedback Cancellation: Two levels of adaptive feedback cancellation help support stable amplification and manage the risk of acoustic feedback during fitting and routine use.

• ENDR 1.0 Noise Reduction: The ENDR 1.0 environment detection and noise reduction system provides up to 17 dB of noise reduction, supporting a more controlled response in the presence of environmental interference.

• Transient Noise Management: Standard transient noise management helps address sudden, short-duration sounds that may otherwise be uncomfortable or distracting.

• Fixed-Direction Dual Microphones: Fixed-direction dual-microphone technology provides a straightforward directional pickup pattern for predefined listening programs.

• Directional Speech Enhancement: Fixed-direction speech enhancement supports focused sound processing in speech-oriented listening situations.

• SIW Technology: SIW technology is integrated into the wider digital signal-processing system and works alongside compression, feedback and noise-management functions.

Bluetooth App Control and Remote Fitting

The confirmed Bluetooth functions for the TW1-BTE-P cover compatible app-based control and fitting. This allows the model to support both professional programming and selected follow-up services within the configured software environment.

Supported app functions include:

• App-based volume control

• App-based program switching

• Remote fitting

• Auto fitting

• Professional fitting

• Smart fitting

For distributors and clinics, this combination can support a more flexible service model. Initial programming can be completed through the selected professional workflow, while compatible remote-fitting tools can be used for later adjustments when appropriate. The final app version, supported languages, account structure and regional deployment requirements can be confirmed during the B2B project stage. Any additional Bluetooth functions required for a specific market should also be confirmed with AcoSound during project evaluation.

Professional Fitting Support

The TW1-BTE-P includes several tools designed to support structured fitting and follow-up:

• Four Selectable Programs: Different listening configurations can be prepared for the expected environments and user requirements.

• Internal Sound-Field Assessment: The integrated sound-field assessment system supports evaluation activities within the configured product ecosystem.

• Internal Audiometer System: The internal audiometer provides an additional fitting-support function for professional workflows.

• Personalized Data Storage: Standard personalized data storage supports continuity between initial programming and later adjustments.

• Memory After Power-Off: Programmed settings and the selected operating state can be retained after the device is switched off.

Daily Operation and Device Management

• Adjustable turn-on delay

• Occlusion effect management

• Low-battery notification

• Adjustable notification volume

• Virtual program switching control

• Virtual volume control

• Memory after power-off

• Nano-coating protective treatment

These functions help fitting teams configure both acoustic behavior and routine device interaction. Nano-coating technology adds a protective surface treatment for everyday handling and exposure without making the device’s operation more complicated for local service teams.

Technical Specifications

An 8-Channel BTE Hearing Aid for B2B Programs

This 8-channel BTE hearing aid gives distributors a defined starting point within the TW BTE-P portfolio. Its commercial role is based on essential digital processing, professional adjustment and Bluetooth-supported fitting rather than on an unnecessarily complex feature package.

For Distributors and Importers

The model can be incorporated into a tiered product range as an 8-channel digital BTE option. Its verified channel, band, DSP and noise-reduction specifications give sales teams concrete points for product comparison and customer qualification.

For Hearing Clinics and Fitting Centers

Professional fitting, selectable programs, assessment-support tools and remote-fitting capability allow the product to be integrated into a service-led workflow rather than sold only as a standalone amplification device.

For Private-Label and OEM/ODM Projects

The TW1-BTE-P provides a technically defined platform for partners developing their own product line. Project discussions can cover software configuration, app functions, packaging, documentation, accessories, language requirements and intended market positioning.
