概览

安森美半导体的 RHYTHM™R3110 混合集成电路是一款预装 DSP 系统,其基于双沟道压缩电路,适用于入门级助听器。R3110 不需要软件配置,也不需要通过计算机配件存储听力学参数,是一种简单、具有成本效益的方案,具有高端助听器的许多功能,包括自适应降噪和自适应声反馈消除。R3110 用于替代老化的模拟方案; 它保持相同的易用性,却具有了数字技术的出色性能。

  • Hearing Aids
  • Pre-Fit Audiology Parameters: All built−in sound processing algorithms are preprogrammed for a wide variety of form-factors and to fit a wide range of hearing loss profiles. The device can also be configured for additional use-cases through hardware settings.
  • Trimmer-Based Fitting: Up to four trimmers can be deployed, offering manufacturers the capability to modify most parameters that are important for patient fitting
  • Mode Control: Provides a variety of user control options: momentary or static switches, as well as an analog volume control
  • Adaptive Feedback Canceller: Automatically reduces acoustic feedback. It allows for an increase in stable gain while minimizing artifacts for music and tonal input signals
  • Automatic Telecoil Support: Supports the use of telecoil devices, enabled either automatically with a magnetic sensitive switch or via an external switch
  • Adaptive Noise Reduction: The adaptive noise reduction algorithm monitors signal and noise activities in 32 individual bands and carefully reduces noise
  • Tinnitus Masking: A noise source can be enabled to mask tinnitus. The noise level is adjustable and mixed with the audio path. Spectral shaping is also possible using the high−cut and low−cut filters.
