The AcoSound TW1-BTE-M is a cost-effective 8-channel digital BTE hearing aid developed for hearing aid distributors, wholesalers, medical device importers, hearing clinics, retail chains, and private-label brands seeking a reliable entry-level professional hearing aid platform.
Positioned as the Essential / Value-Tier model in the TW BTE-M product family, the TW1-BTE-M combines 8 independent compression and amplification channels, 16 adjustable frequency bands, and 32 DSP processing channels with professional fitting, app-based adjustment, remote fitting, and essential digital noise-management technologies.
Its shared BTE-M acoustic platform delivers a maximum OSPL90 of 123 dB, an HFA OSPL90 of 118 dB, a maximum FOG50 gain of 46 dB, and an HFA full-on gain of 38 dB.
For B2B buyers, the TW1-BTE-M provides a practical balance between professional digital processing, controlled product cost, and flexible fitting capabilities. It is particularly suitable for entry-level product lines, price-sensitive markets, regional distribution, private-label programs, and volume purchasing.
ACOD3101 Intelligent DSP Platform
The TW1-BTE-M is powered by the ACOD3101 intelligent multi-core digital signal processing platform.
Its processing architecture includes:
8 independent compression and amplification channels
16 adjustable frequency bands
32 DSP processing channels
4 selectable hearing programs
The 8-channel architecture provides frequency-specific fitting flexibility, while 16 adjustable bands allow hearing professionals to further shape the frequency response according to fitting requirements.
For distributors, this configuration provides an accessible professional BTE platform without moving into the higher-cost processing technologies of TW2-BTE-M and TW3-BTE-M.
BTE-M Acoustic Performance
The TW1-BTE-M shares the core acoustic platform used across the TW BTE-M range.
Key acoustic specifications include:
Maximum OSPL90: 123 dB
HFA OSPL90: 118 dB
Maximum FOG50 Gain: 46 dB
HFA Full-On Gain: 38 dB
Reference Test Gain: 38 dB
Equivalent Input Noise: 25 dB
THD: 3%
Frequency Range: 200–5000 Hz
Battery Current: 2.4 mA
These specifications provide distributors with a consistent acoustic foundation while allowing the three BTE-M models to be differentiated primarily by digital processing, environmental management, and fitting resolution.
ERAC 1.0 Dual-Knee Compression
The TW1-BTE-M uses ERAC 1.0 intelligent multi-compression technology with dual-knee processing.
The system is designed to manage different input levels while supporting controlled amplification across multiple frequency regions.
Combined with the 8-channel fitting structure, ERAC 1.0 provides a practical compression platform for entry-level professional BTE hearing aid applications.
ENDR 1.0 Noise Reduction
The TW1-BTE-M incorporates ENDR 1.0 Environmental Detection and Noise Reduction technology, providing up to 17 dB noise reduction.
The system helps reduce unwanted environmental noise while preserving useful acoustic information.
For B2B buyers, ENDR 1.0 creates a clear essential technology tier below the more advanced ENDR 2.0 platform available in TW2-BTE-M and TW3-BTE-M.
DFBC 2.0 Feedback Cancellation
The TW1-BTE-M incorporates DFBC 2.0 feedback cancellation with two levels.
This technology helps reduce unwanted acoustic feedback and supports stable amplification during professional fitting and daily operation.
For distributors and clinics, reliable feedback management provides an important baseline feature for a professionally fitted digital BTE hearing aid.
App Control and Professional Fitting
The TW1-BTE-M supports:
These functions allow hearing care providers and distributor service teams to support both traditional in-person fitting and remote service models.
For B2B customers, this can improve fitting flexibility and after-sales support efficiency.
