AYRESA3291: Pre-configured Wireless DSP System for Hearing Aids, with up to 8 WDRC channels

Ayre™ SA3291 is a pre-configured wireless DSP system utilizing Near-Field Magnetic Induction (NFMI) technology. 

技术特性
  • Binaural Synchronization: The binaural synchronization feature allows two hearing aids to wirelessly synchronize adjustments such as program modes or volume control. By working together as one system, user control is simplified.
  • Binaural Telecoil: The binaural telecoil wirelessly streams telecoil audio signals from one hearing aid to the other. This enables hearing aid users to hear phone calls in both ears, improving speech intelligibility.
  • Stereo Audio Streaming: Stereo audio signals can be streamed wirelessly from a relay device to hearing aids equipped with Ayre SA3291. A relay device can use Bluetooth or other far-field wireless technology to wirelessly connect with TVs, music players, mobile phones or other audio sources.
  • iSceneDetect Environment Classification: The environmental classification algorithm automatically optimizes the hearing aid to maximize comfort and audibility by analyzing the hearing aid wearers acoustic environment.
  • Adaptive Noise Reduction: The adaptive noise reduction algorithm monitors noise levels independently in 128 individual bands and employs advanced psychoacoustic models to provide user comfort.
  • Tinnitus Masking: Comes equipped with internal noise generation for tinnitus treatment. The noise can be shaped and attenuated and then summed into the audio path either before or after the volume control.
  • Adaptive Feedback Cancellation: Automatically reduces acoustic feedback and allows for an increase in the stable gain while minimizing artifacts for music and tonal input signals.
  • Automatic Adaptive Directionality: The automatic Adaptive Directional Microphone (ADM) algorithm automatically reduces the level of sound from sources originating behind or to the side of the hearing aid wearer, without affecting sounds from the front. The algorithm also reduces current consumption by gathering input from the acoustic environment and automatically selecting whether directionality is needed or not.
