Product Overview

The TW2-BTE-P is a 12-channel BTE hearing aid with digital processing for distributors, hearing centers, importers and brand owners seeking a differentiated middle tier. It expands fitting resolution and environmental sound management while maintaining practical professional fitting, local service and Bluetooth-supported follow-up.

The model combines 12 independent compression and amplification channels, 24 adjustable bands and 48 DSP channels. It also adds standard environment recognition, ENDR 2.0 noise reduction, noise-source tracking, wind noise management and standard directional processing. These verified differences support its position between the TW1-BTE-P and the self-adaptive TW3-BTE-P.

Expanded 12-Channel BTE Hearing Aid Adjustment

12 Compression and Amplification Channels

Twelve independent channels give the fitting professional a more detailed framework for controlling amplification and compression across the frequency range. The additional adjustment points support more precise development and refinement of the programmed response while keeping the fitting structure manageable for clinic teams.

24 Independently Adjustable Bands

The 24-band configuration provides greater frequency-specific adjustment than the 16-band platform of the TW1-BTE-P. Fitters can use this expanded resolution when shaping the response for the selected fitting strategy, acoustic coupling and individual requirements. For distributors, the band count also creates an easy-to-understand specification for product comparison and tiered portfolio design.

48 DSP Channels

Forty-eight DSP channels support compression, feedback control, environment recognition, noise management and directional processing, creating a defined technical step between the 32-channel TW1-BTE-P and 64-channel TW3-BTE-P.

Multi-Core Digital Processing

ACOD3101 Processing Platform

The ACOD3101 intelligent multi-core DSP supports coordinated amplification, compression, feedback control, environmental noise management, directional processing and fitting functions.

ERAC 1.0 Dual-Knee Technology

ERAC 1.0 context-analysis-based intelligent multi-compression technology uses a dual-knee structure to manage gain behavior as the incoming sound level changes. This gives the fitting professional an adjustable compression framework for softer, moderate and stronger sounds. The programmed response can be stored as personalized data and refined during later follow-up.

Environment Recognition and Noise Management

The TW2-BTE-P adds a broader sound-management package for varied daily environments.

• Standard Environment Recognition: The environment recognition management system provides a structured response as surrounding sound conditions change.

• ENDR 2.0 Noise Reduction: The ENDR 2.0 environment detection and noise reduction system provides up to 20 dB of noise reduction, creating a defined upgrade from the ENDR 1.0 configuration of the TW1-BTE-P.

• Noise-Source Tracking and Suppression: Standard tracking and suppression functions help identify and manage sources of environmental interference within the processing system.

• Transient Noise Management: Standard transient noise processing helps address sudden, short-duration sounds.

• Wind Noise Management: Standard wind noise management adds a dedicated function for outdoor and air-movement conditions.

• SIW Technology: SIW technology forms part of the coordinated signal-processing platform.

Together, these functions give distributors and clinics a defined environmental management package with specific, explainable capabilities.

Directional Speech Processing

The specification lists standard directional dual-microphone technology and standard directional speech enhancement for the TW2-BTE-P. These functions work together to support speech-oriented listening programs and provide a defined step beyond the fixed-direction configuration of the TW1-BTE-P.

DFBC 2.0 Feedback Cancellation

DFBC 2.0 provides two levels of adaptive feedback cancellation. It supports stable amplification and helps manage feedback risk across different fitting conditions. The function works as part of the professional fitting process together with physical fit, acoustic coupling and programmed gain.
