AudiCore™ Hearing Performance Technology

AXIL AudiCore™ Hearing Performance technology is constantly evolving in the most advanced science(s) of digital hearing technology. Our AudiCore™ Digital Processing Circuitry converts sound waves of all types into actual digital code. AudiCore™ circuitry then reshapes the digital code and sends it to the miniaturized receiver (speaker). The receiver/speaker recreates a whole new sound based on the recalculations of the digital algorithms within the circuitry.

4.0- AudiCORE™ 4.0 delivers the most wide range, full sound experience available- no matter where you are or what your hearing needs may be. Experience rich, full sound across the entire sound spectrum with additional clear high fidelity emphasis. Supports any level of hearing loss you have and gain requirements your AXIL device will need. AC 4.0 offers the most cutting-edge Background Noise Layered Filtering, Adaptive Feedback Management and Tinnitus Masking technologies in the world.

AC 4.0 Offers Rapidfire™ Digital Compression (RFDC) to give you the most advanced multi-attack response time possible. You’ll be able to enter the most aggressive sound environments of any kind- knowing you have the hearing protection to adjust automatically and keep up with any demands you put on it. RapidFire™easily and automatically handles the loudest noises from all angles and several sound points to give you the maximum protection every time.

AC 4.0 RapidFire™ is the only microprocessor to handle hearing protection in a unique way; only cutting out loud sounds over 85 dB without affecting the sounds coming through under 85 dB. No more interruption of sound when you need it most.

AC 4.0 is Our Top of the Line Technology.

Liquify™ Waterproofing (Optional)

AXIL has introduced and continues to lead the way in internal waterproofing. Traditional methods use cumbersome rubber pieces internally to keep moisture and water out. These wear out and are inefficient from the start.

Our Liquify™ process utilizes a patented liquid technology sealing all internal components for total waterproofing.
