The AcoSound TW2-BTE-M is an advanced 12-channel digital BTE hearing aid developed for hearing aid distributors, clinics, medical device importers, wholesalers, retail chains, and private-label brands seeking a balanced combination of fitting precision, noise management, directional processing, and commercial value.

Positioned as the Advanced / Core-Selling model in the TW BTE-M family, the TW2-BTE-M provides a substantial processing upgrade over TW1-BTE-M.

Its technology platform combines:

• 12 compression and amplification channels

• 24 adjustable frequency bands

• 48 DSP processing channels

• ERAC 2.0 multi-knee compression

• DFBC 3.0 Advanced feedback cancellation

• ENDR 2.0 noise reduction up to 20 dB

• Standard environment recognition

• Medium-level noise-source tracking

• Advanced directional dual microphones

• Advanced directional speech enhancement

• Intelligent wind-noise management

• Intelligent transient-noise management

For B2B buyers, TW2-BTE-M is particularly suitable as a mainstream or core-selling BTE model positioned between an essential value product and a premium flagship solution.

12-Channel Processing with 48 DSP Channels

TW2-BTE-M is powered by the ACOD3101 intelligent multi-core DSP platform.

Its processing architecture includes:

• 12 independent compression and amplification channels

• 24 adjustable frequency bands

• 48 DSP processing channels

• 4 selectable hearing programs

Compared with TW1-BTE-M, the additional channels and bands provide greater fitting resolution and more detailed frequency-response control.

For hearing care professionals, this supports more precise professional fitting.

For distributors, it provides a clear technical and commercial upgrade over an entry-level 8-channel product.

Shared BTE-M Acoustic Performance

TW2-BTE-M shares the same acoustic platform as TW1-BTE-M and TW3-BTE-M:

• 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

This allows distributors to maintain consistent acoustic performance while differentiating models through processing technology and fitting resolution.

ERAC 2.0 Multi-Knee Compression

TW2-BTE-M upgrades to ERAC 2.0 intelligent multi-compression technology with multi-knee processing.

Compared with ERAC 1.0 used in TW1-BTE-M, the ERAC 2.0 architecture provides more advanced compression management across different input sound levels.

Combined with 12 independent channels and 24 adjustable bands, it supports more flexible professional fitting.

ENDR 2.0 Noise Reduction

TW2-BTE-M incorporates ENDR 2.0 Environmental Detection and Noise Reduction technology, providing up to 20 dB noise reduction.

This represents a clear upgrade over the ENDR 1.0 system used in TW1-BTE-M.

The device also includes medium-level noise-source tracking and suppression, strengthening its environmental processing capabilities.

Standard Environment Recognition

TW2-BTE-M introduces a standard Environment Recognition Management System.

This enables the platform to identify changes in the acoustic environment and support appropriate processing strategies.

For distributors, this creates a meaningful technology step between the essential TW1-BTE-M and the self-adaptive TW3-BTE-M.

Advanced Directional Processing

TW2-BTE-M incorporates:

• Advanced directional dual-microphone technology

• Advanced directional speech enhancement

• Medium-level noise-source tracking and suppression

These technologies create one of the most important performance differences between TW1-BTE-M and TW2-BTE-M.

For B2B buyers, this provides a strong reason to position TW2 as the mainstream advanced model.

Intelligent Wind and Transient Noise Management

TW2-BTE-M includes:

• Intelligent wind-noise management — 2 levels

• Intelligent transient-noise management — 2 levels

These technologies provide additional environmental processing flexibility and support the Advanced product tier.

DFBC 3.0 Advanced Feedback Cancellation

TW2-BTE-M upgrades to DFBC 3.0 Advanced Feedback Cancellation.

Compared with the DFBC 2.0 technology used in TW1-BTE-M, this provides a more advanced feedback-management architecture designed to support stable amplification and professional fitting.

App and Professional Fitting

TW2-BTE-M supports:

• App volume control

• App program switching

• Remote fitting

• Automatic fitting

• Professional fitting

• Smart fitting

• Virtual-button volume control

• Virtual-button program switching

• Memory after power-off

These functions support both clinic-based fitting and remote after-sales service models.
