Product Overview

The L8-BTE-H is an 8 channel fixed direction BTE hearing aid developed for hearing aid distributors, audiology clinics, hearing centers, medical device importers and professional hearing care organizations that need greater fitting capacity together with a defined directional-processing step in the L-BTE-H family.

Built on the ACOD2101 intelligent multi-core DSP platform, the model provides 8 independently adjustable compression and amplification channels, 16 independently adjustable bands and 32 DSP channels. ERAC 1.0 Context Analysis Based Intelligent Multi-Compression Technology with a Dual-Knee structure forms the compression architecture.

Feedback management is provided by AFC 2.0 Adaptive Feedback Cancellation together with SIW technology. ENDR 1.0 Environment Detection and Noise Reduction is specified at up to 17 dB. Standard Transient Noise Management is included.

The main directional distinction is Fixed Direction Dual-Microphone Technology together with Fixed Directional Speech Enhancement Technology. This gives L8-BTE-H a clearer role between the All Direction entry configuration and the Standard environmental-processing tier introduced at L12-BTE-H.

Fixed Direction as the Main Selection Point

Directionality is the central product differentiator of L8-BTE-H.

Compared with L4-BTE-H, the microphone configuration changes from All Direction to Fixed Direction, and Directional Speech Enhancement changes from No to Fixed. Standard Transient Noise Management is also introduced at this model level.

For distributors evaluating an 8 channel fixed direction BTE hearing aid, these changes provide a practical reason to position the model above the entry configuration without relying only on channel count.

The model does not include Environment Recognition, Noise Source Tracking and Suppression or Wind Noise Management. Those functions appear at the Standard level in L12-BTE-H and L16-BTE-H. This keeps the role of L8-BTE-H clear within the four-model product ladder.

8 / 16 / 32 Fitting Structure

L8-BTE-H provides:

• 8 independently adjustable compression and amplification channels
• 16 independently adjustable bands
• 32 DSP channels

The 8 / 16 / 32 architecture doubles the corresponding fitting figures of L4-BTE-H. For hearing care teams, this provides additional adjustment capacity. For distributors, it creates a simple numerical identity for technical sheets, quotations and product training.

For buyers considering an 8 channel fixed direction BTE hearing aid, the fitting structure can be assessed together with Fixed Direction processing and Standard Transient Noise Management.

This combination gives the model a distinct mid-range role: higher fitting capacity than L4-BTE-H, but a narrower environmental-management package than the Standard tier used in L12-BTE-H and L16-BTE-H.

Noise Reduction and Feedback Platform

L8-BTE-H continues to use ERAC 1.0 Multi-Compression Technology with a Dual-Knee structure.

Feedback management is provided by AFC 2.0 Adaptive Feedback Cancellation, supported by SIW technology. ENDR 1.0 is specified at up to 17 dB.

Standard Transient Noise Management is included. Wind Noise Management is not included. Environment Recognition and Noise Source Tracking and Suppression are also not included at this configuration level.

For B2B product comparison, these specifications help separate the model from both adjacent tiers. L4-BTE-H has a simpler directional and transient-noise configuration, while L12-BTE-H introduces DFBC 2.0, Standard Environment Recognition and additional Standard environmental-management functions.

Electroacoustic Reference Data

L8-BTE-H shares the documented electroacoustic profile of the L-BTE-H family. Maximum OSPL90 is 134 dB and HFA OSPL90 is 126 dB. Maximum FOG50 is 63 dB and HFA FOG50 is 55 dB. RTG Target and RTG Measured are both 55 dB.

The frequency range is 200–5000 Hz, battery current is 1.5 mA, EQ is 20 dB and THD at 500 Hz, 800 Hz and 1600 Hz is specified at 3%.

For distributors, these values provide a stable reference for sample evaluation and technical documentation while the model-specific fitting and directional functions are compared.

For professional buyers evaluating an 8 channel fixed direction BTE hearing aid, the electroacoustic profile can be reviewed together with the 8 / 16 / 32 fitting architecture and Fixed Direction technologies.

Professional Operating Functions

L8-BTE-H provides 4 selectable programs and includes an Internal Sound Field Assessment System and Internal Audiometer System.

Additional functions include Adjustable Turn-on Delay, Occlusion Effect Management, Low Battery Power Notification, Adjustable Notification Volume, Volume Control, FM Interface Compatibility, Auto Phone Function and Memory After Power-off.

Personalized Data Storage is specified as Standard. Nano Coating Technology is included.

These functions give clinics, hearing centers and distributors a consistent professional operating specification while the fitting and signal-processing configuration changes across the series.

B2B Product Role

As an 8 channel fixed direction BTE hearing aid, L8-BTE-H is suitable for distributors, importers, audiology clinics and hearing centers that need an intermediate configuration with greater fitting capacity and a defined directional-processing step.

Its product identity is centered on 8 fitting channels, 16 adjustable bands, 32 DSP channels, AFC 2.0, ENDR 1.0 up to 17 dB, Standard Transient Noise Management, Fixed Direction Dual-Microphone Technology and Fixed Directional Speech Enhancement.

This gives distributors a straightforward basis for positioning L8-BTE-H between the entry configuration and the Standard environmental-processing tier.
