Overview

Ayre™ SA3291 は、近接場磁気誘導 (NFMI) テクノロジーを利用した事前構成済みワイヤレス DSP システムです。 補聴器で Ayre SA3291 を使用すると、プログラム・モードやボリューム・コントロールをワイヤレスで同期し、1 つの補聴器から別の補聴器へテレコイル信号をストリーミングできるようになります。リレー・デバイスと連動すれば、Ayre SA3291 で、リモート・コントロール機能に加え、ステレオ・オーディオ・ストリーミングなどの機能を Bluetooth® 経由で実現できます。iSceneDetect 環境分類、適応型ノイズ低減、卓越したフィードバック・キャンセレーション、完全自動化および適応型マイクロフォン方向性、最大8個の WDRC チャネルが特徴の Ayre SA3291 は、フル機能を備えたハイエンドのワイヤレス製品に理想的です。SupportARK は、ソフトウェア構築ブロックを集めたソフトウェアで、補聴器調整ソフトウェアの開発にかかる時間の短縮に役立ちます。ARKonline は、製品ライブラリの作成や、作成したライブラリの整理に効果的な Web ベースのツールです。ARKonline には以下からアクセスできます。www.onsemi.com/arkonline.

  • Digital Audio Processing

  • Hearing Aids

  • 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.
