Product Overview

The L4-RIC-S-N is a 4 channel self-adaptive RIC hearing aid developed for hearing aid distributors, audiology clinics, hearing centers and professional hearing care organizations that require a compact fitting architecture with a clearly defined environmental-processing package.

Built on the ACOD2101 intelligent multi-core DSP platform, the device provides 4 independently adjustable compression and amplification channels, 8 independently adjustable bands and 16 DSP channels. Its signal-processing architecture combines ERAC 2.0 Dual-Knee compression, DFBC 3.0 Advanced Feedback Cancellation with two levels, DFBC + Advanced SIW technology, Self-Adaptive Environment Recognition and ENDR 2.0 noise reduction specified at up to 20 dB.

The model also includes two levels of Intelligent Transient Noise Management and two levels of Intelligent Wind Noise Management. Four selectable programs, an Internal Sound Field Assessment, an Internal Audiometer and Medium personalized data storage support professional fitting, assessment and routine device management.

For B2B buyers, L4-RIC-S-N provides a distinct option for product portfolios that need a lower channel-count configuration together with a broader set of signal-processing and environmental-management functions.

Compact 4 / 8 / 16 Fitting Architecture

L4-RIC-S-N uses a straightforward 4 / 8 / 16 structure: 4 independently adjustable fitting channels, 8 independently adjustable bands and 16 DSP channels.

The fitting structure gives hearing care professionals defined frequency-specific adjustment points while keeping the overall channel architecture compact. The ACOD2101 processor provides the digital foundation for compression, feedback management, environment recognition and noise-management functions.

For distributors, the numerical structure is easy to communicate in technical catalogs, product training and specification comparisons. It gives professional buyers clear data points for evaluating the model within a broader RIC product portfolio.

The combination of compact fitting capacity and a broader processing package gives L4-RIC-S-N a clearly defined role for customers that value processing functions as well as channel configuration.

ERAC 2.0 Dual-Knee Compression

The product uses ERAC 2.0 Context Analysis Based Intelligent Multi-Compression Technology with a Dual-Knee structure.

ERAC 2.0 forms part of the digital amplification architecture and operates across the independently adjustable fitting channels. The technology provides a defined compression platform for managing input levels within the fitting system.

For professional hearing care organizations, this creates a clear technical foundation that can be incorporated into fitting and adjustment workflows.

For distributors, the ERAC 2.0 specification also provides another technical criterion when comparing products that may share a similar RIC form factor or fitting-channel count.

DFBC 3.0 Advanced Feedback Management

Feedback management is provided by DFBC 3.0 Advanced Feedback Cancellation with two levels. The model also includes DFBC + Advanced SIW technology.

Together, these functions form the feedback-management architecture of the device and create a specific technical configuration that can be considered alongside compression, Environment Recognition and noise reduction.

For professional buyers, DFBC 3.0 Advanced provides a clearly defined processing specification for technical comparison.

For distributors, the feedback architecture can also be incorporated into product training, specification sheets and B2B sales discussions when differentiating the model within a multi-tier product portfolio.

Self-Adaptive Environment Recognition

L4-RIC-S-N includes a Self-Adaptive Environment Recognition Management System.

This function forms part of the wider environmental-processing package and works alongside ENDR 2.0, Intelligent Transient Noise Management and Intelligent Wind Noise Management.

The Self-Adaptive processing level gives the model a clearly defined environmental-management specification while retaining a compact fitting architecture.

For hearing centers and audiology clinics, this combination provides several technical functions that can be considered during model selection and professional fitting.

For distributors, the environmental-processing package helps differentiate L4-RIC-S-N from streamlined four-channel configurations while retaining the same compact channel structure.

ENDR 2.0 and Two-Level Environmental Noise Management

Noise reduction is provided by ENDR 2.0 Environment Detection and Noise Reduction, specified at up to 20 dB.

The model also provides:

• Intelligent Transient Noise Management — 2 Levels
• Intelligent Wind Noise Management — 2 Levels

These functions create a structured environmental-noise management package and give professional customers several defined processing parameters for product selection.

For B2B product planning, the combination of ENDR 2.0, transient-noise management and wind-noise management provides useful specification points for catalog organization, distributor training and professional product comparison.

This processing package also helps the model maintain a distinct role where environmental-management capability is an important selection criterion despite the compact fitting-channel structure.

Professional Fitting and Assessment Functions

The product provides 4 selectable programs together with an Internal Sound Field Assessment and Internal Audiometer.

Additional device functions include adjustable turn-on delay, occlusion effect management, low-battery notification, adjustable notification volume, volume control and memory after power-off.

L4-RIC-S-N uses Medium personalized data storage, and Nano Coating Technology is included.

These functions support professional fitting, assessment and routine device management across hearing centers, audiology clinics and other professional hearing care channels.

The combination of built-in assessment functions and device-management capabilities also supports organizations where fitting and follow-up services form an important part of the professional workflow.

B2B Product Positioning

L4-RIC-S-N is suitable for hearing aid distributors, audiology clinics, hearing centers, medical device importers and professional hearing care networks that require a compact fitting platform with a clearly specified processing package.

Its commercial differentiation is based on the combination of 4 fitting channels, 8 adjustable bands, 16 DSP channels, ERAC 2.0, DFBC 3.0 Advanced, Self-Adaptive Environment Recognition, ENDR 2.0 up to 20 dB and two-level transient and wind-noise management.

This combination allows distributors to position the product in a portfolio where channel count is not the only selection criterion. Professional buyers can evaluate the model using fitting structure, feedback technology, Environment Recognition and environmental noise-management specifications.

For multi-tier product planning, this creates a useful option between streamlined low-channel configurations and higher-channel platforms.

The model can therefore support clearer catalog segmentation, technical training and specification-based sales discussions across professional hearing care channels.
