Product Overview

The L8-BTE-P is an 8 channel directional BTE hearing aid developed for hearing aid distributors, audiology clinics, hearing centers and professional hearing care organizations that need greater fitting capacity and a defined directional-processing configuration within the L-BTE-P range.

The model provides 8 independently adjustable compression and amplification channels, 16 independently adjustable bands and 32 DSP channels on the ACOD2101 platform.

Its core electroacoustic values remain clearly documented: maximum OSPL90 is 128 dB, HFA OSPL90 is 116 dB, maximum FOG50 is 51 dB and HFA FOG50 is 41 dB. Frequency range is specified at 200–5500 Hz.

What distinguishes L8-BTE-P from the entry configuration is not only the larger fitting structure. The model introduces Fixed Direction Dual-Microphone Technology, Fixed Directional Speech Enhancement and Standard Transient Noise Management, while ENDR 1.0 increases to a specified maximum of 17 dB.

For B2B product planning, these changes give L8-BTE-P a clear middle position between the basic All Direction configuration and the broader environmental-processing platform introduced at L12-BTE-P.

Fixed Direction as the Main Selection Point

Directionality is the central product story of L8-BTE-P.

The model provides:

• Fixed Direction Dual-Microphone Technology
• Fixed Directional Speech Enhancement Technology

This creates a clear specification difference from L4-BTE-P, where the microphone mode is All Direction and Directional Speech Enhancement is not included.

At the same time, L8-BTE-P remains distinct from the upper models, where directional processing is specified as Standard.

For distributors evaluating an 8 channel directional BTE hearing aid, this makes directionality a practical selection criterion in addition to channel count.

It also provides a stronger product-training story than simply presenting L8 as “twice the channels” of L4.

8 / 16 / 32 Fitting Structure

L8-BTE-P provides:

• 8 fitting channels
• 16 adjustable bands
• 32 DSP channels

The 8 / 16 / 32 structure doubles the corresponding fitting figures of L4-BTE-P.

For clinics and hearing centers, this increases frequency-specific adjustment capacity.

For distributors, the architecture provides measurable specifications for comparison sheets, catalog positioning and sales discussions.

An 8 channel directional BTE hearing aid with a 32-DSP-channel configuration can therefore be presented around a combination of fitting resolution and directional processing rather than generalized marketing claims.

Noise and Feedback Processing

L8-BTE-P 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 with two levels, together with SIW technology.

ENDR 1.0 is specified at up to 17 dB.

Standard Transient Noise Management is included.

Environment Recognition, Noise Source Tracking and Suppression, and Wind Noise Management are not included in this configuration.

This clearly defined processing boundary prevents the product from overlapping unnecessarily with L12-BTE-P.

Electroacoustic Reference

The model shares the following documented P-series electroacoustic profile:

• Maximum OSPL90: 128 dB
• HFA OSPL90: 116 dB
• Maximum FOG50: 51 dB
• HFA FOG50: 41 dB
• RTG Target / Measured: 41 / 41 dB
• Frequency Range: 200–5500 Hz
• Battery Current: 1.4 mA
• EQ: 25 dB

For B2B buyers, these common figures provide a stable baseline while the changing fitting, directionality and environmental-management specifications are compared across the series.

Professional Workflow Functions

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

It also includes adjustable turn-on delay, occlusion effect management, low-battery notification, adjustable notification volume, volume control, FM Interface Compatibility, Auto Phone Function and memory after power-off.

Personalized Data Storage is Standard.

Nano Coating Technology is included.

These functions support assessment, fitting and routine device management across professional hearing care workflows.

B2B Portfolio Role

As an 8 channel directional BTE hearing aid, L8-BTE-P is suitable for distributors that need an intermediate configuration between the entry L4 model and the upper environmental-processing tier.

Its product identity is based on 8 fitting channels, 16 adjustable bands, 32 DSP channels, Fixed Direction technologies, Standard Transient Noise Management and ENDR 1.0 up to 17 dB.

This gives buyers several measurable reasons to select L8-BTE-P while preserving a clear path to L12-BTE-P when Environment Recognition, Noise Source Tracking and Suppression or Wind Noise Management becomes part of the specification requirement.
