ADVANTA-OPEN™ is a product built on the VOYAGEUR™ platform with ADRO® technology from Dynamic Hearing. ADRO® is a high-end alternative to standard compression schemes used in hearing aids, and employs fuzzy logic and an adaptive algorithm to optimize the hearing aid signal so that sounds remain within the dynamic range of the listener. Advanta-Open specifically targets open-fit hearing aid products with extremely fast signal processing using the unique ULD (Ultra Low Delay) ADRO® amplification strategy, delivering sub 1.5 ms processing latency.
Harnessing the power of Voyageur, Advanta-Open is a product featuring extremely fast signal processing with the unique ULD ADRO® amplification strategy for high-end hearing aids. With sub 1.5 ms processing latency, adaptive directional microphone system, adaptive feedback canceller, adaptive feedback suppression and low-level noise reduction, Advanta-Open delivers unprecedented performance.
ADRO® is a flexible, digital, output-based amplifier that dynamically adapts to different sound environments, providing superior audibility and loudness comfort, automatic optimization of speech intelligibility in noise, and high quality sound in any environment. Advanta-Open features the ADRO® ULD amplification specially targeted for open-fit hearing aid products. The ADRO® ultra low delay amplification strategy improves speech perception in quiet and noisy environments. Customized fuzzy-logic rules are used to dynamically adjust the signal to the listener's hearing range.
ADAPTIVE DIRECTIONAL MICROPHONE (ADM) technology on Advanta-Open enhances the user experience with continuous and automatic adjustment of the microphone settings based on the environment adjust depending on environment. Combining the signals from two omni-directional microphones allows unwanted noise to be rejected while an adjustable threshold criterion allows the system to automatically change to an omni-directional response when in quiet. The ADM features a flat frequency response, is easily configured for different microphone placements, and each is calibrated to match multiple microphones. For noisy situations, directional modes are utilized
ADAPTIVE FEEDBACK SUPPRESSION AND ADAPTIVE FEEDBACK CANCELLER work in tandem to provide an integrated feedback management system. The advanced feedback canceller provides increased maximum stable gain with rapid feature adjustment for dynamic feedback situations. Additionally, the feedback is cancelled without reducing forward-path gain.
LOW LEVEL NOISE REDUCTION on Advanta-Open reduces noise without introducing audible artifacts, enhancing use with mild hearing loss.
Furthermore, Advanta-Open is equipped with numerous configurable options including: fixed directional microphone, internal noise reduction with user programmable settings, adjustable volume control range, direct audio input, telecoil input, calibration and test modes supporting standard IEC/ANSI procedures, adjustable input selection and 4 alternate listening programs.
