Audiology DSP Systems | AYRE SA3291
概览
Ayre™ SA3291 是一个预先配置的 DSP 系统，采用近场磁感应 (NFMI) 技术。 Ayre SA3291 让助听器能够以无线方式进行程序模式同步和音量控制，还能将电信线圈信号从一个助听器流化到另一个助听器。耦合继电器器件时，Ayre SA3291 还能通过 Bluetooth® 实现立体声等功能，还具有远程控制功能。Ayre SA3291 具有 iSceneDetect 环境等级、自适应噪音抑制、卓越的反馈抑制、全自动和自适应麦克风方向性以及最多 8 沟道 WDRC，适用于高端全功能无线产品。SupportARK 是一组软件构造块，有助于缩短开发助听器安装软件所需的时间。ARKonline 是一款基于 Web 的高效工具，用于创建产品库和保持它们的有序组织形式。要访问 ARKonline，请转至 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.
