Product Overview

The TW1-BTE-M is an 8-channel digital BTE hearing aid developed for hearing-aid distributors, medical device importers, hearing clinics, fitting centers and private-label partners. It combines essential multichannel processing with professional programming and compatible Bluetooth app functions, giving B2B customers a practical entry model for a structured digital hearing-aid portfolio.

With 8 independent compression and amplification channels, 16 independently adjustable bands and 32 DSP channels, the product provides a defined technical foundation for fitting and product comparison. ERAC 1.0 dual-knee compression, DFBC 2.0 feedback cancellation, ENDR 1.0 noise reduction and four selectable programs support routine professional configuration without adding features that may be unnecessary for an entry-level market position.

For channel partners, the TW1-BTE-M offers clear differentiation through verified specifications, app-supported fitting and a BTE format that can be incorporated into clinic-led, distributor-led and OEM/ODM product programs. The 8-channel digital BTE hearing aid is positioned around dependable fitting control and a clearly defined foundational feature set.

8-Channel Fitting Architecture

Independent Compression and Amplification Channels

The TW1-BTE-M provides 8 independent compression and amplification channels. These channels allow a fitting professional to organize gain and compression behavior across different parts of the frequency range instead of applying only broad overall amplification. This supports repeatable programming and helps service teams document adjustments during initial fitting and follow-up.

16 Independently Adjustable Bands

Sixteen adjustable bands give the fitter additional frequency-specific control. The combination of 8 processing channels and 16 bands creates a practical balance between programming capability and operational simplicity. For distributors building a tiered range, this specification gives sales teams a concrete way to distinguish the 8-channel digital BTE hearing aid from higher-channel models.

32 DSP Channels

The ACOD3101 intelligent multi-core DSP operates with 32 DSP channels. This processing platform supports compression, feedback management, noise reduction and program control while maintaining a clearly defined specification for training, comparison and product documentation.

Compression, Feedback and Noise Management

ERAC 1.0 Dual-Knee Compression

ERAC 1.0 context-analysis-based intelligent multi-compression technology uses a dual-knee structure. It provides a controlled framework for managing amplification across different input levels and gives the fitting professional a consistent basis for programming. Final settings should be selected according to the applicable fitting procedure and individual assessment.

DFBC 2.0 Feedback Cancellation

DFBC 2.0 adaptive feedback cancellation provides two levels of control. It is designed to support stable amplification and help manage acoustic feedback during fitting and routine operation. The two-level configuration gives fitting teams a defined adjustment option without suggesting that every acoustic environment will require the same setting.

ENDR 1.0 Noise Reduction

ENDR 1.0 environment detection and noise reduction provides up to 17 dB of noise reduction. Standard transient noise management is also included to help manage sudden, short-duration sounds. The streamlined TW1-BTE-M configuration focuses on these core noise-control functions; partners requiring environment recognition, noise-source tracking, wind-noise management or directional dual-microphone processing can compare TW2-BTE-M and TW3-BTE-M.

The resulting feature package makes the 8-channel digital BTE hearing aid suitable as a clearly specified foundational product, while TW2-BTE-M and TW3-BTE-M provide higher processing tiers for markets requiring additional environmental and directional functions.

Bluetooth App Control and Professional Fitting

The confirmed Bluetooth functions of the TW1-BTE-M relate to compatible app control and fitting. Supported functions include:

• App-based volume control

• App-based program switching

• Remote fitting

• Auto fitting

• Professional fitting

• Smart fitting

These functions can support a more flexible service workflow for distributors and hearing centers. Initial programming can be completed through the selected professional process, while compatible remote-fitting functions may support later adjustments where appropriate. The final app version, supported languages, account structure and regional deployment conditions should be confirmed during project evaluation.

Wireless requirements beyond this app-control and fitting scope can be reviewed with AcoSound during product evaluation.

Professional Fitting and Device Management

Four selectable programs allow fitting teams to prepare different configurations for the expected listening situations. The internal sound-field assessment system and internal audiometer system provide additional functions within the supported fitting ecosystem. Personalized data storage is specified at the standard level, supporting continuity between programming sessions.

The 8-channel digital BTE hearing aid also includes adjustable turn-on delay, occlusion effect management, low-battery notification, adjustable notification volume, volume control, virtual program switching, virtual volume control and memory after power-off. Nano-coating technology provides a protective surface treatment for routine handling.
