产品信息

Rhythm™ R3910 is a preconfigured DSP system based on the powerful WOLVERINE platform.
Featuring iSceneDetect™ environmental classification, adaptive noise reduction, superior feedback cancellation, fully automated and adaptive microphone directionality, and up to 8-channel WDRC, the Rhythm R3910 is ideal for high-end, full featured products.
Available in one of the industry's smallest form-factors, it is well suited for all hearing aid types, including those placed deep in the ear canal.
Software Support
ARK is a set of software building blocks that can help reduce the time it takes to develop hearing aid fitting software. ARKonline is an efficient web-based tool for creating product libraries and keeping them organized. To access ARKonline, please go to

The iSceneDetect 1.0 environmental classification algorithm is capable of analyzing the hearing aid wearers acoustic environment and automatically optimizes the hearing aid to maximize comfort and audibility.
Enables the recording of various hearing aid parameters such as program selection, volume setting and ambient sound levels. The sampling interval can be configured to record from every 4 seconds up to once every 60 minutes. The fitting system can present the data to help the fitting specialist fine tune the hearing aid and counsel the wearer.
Allows manufacturers to provide more pleasing, multi-frequency tones simulating musical notes or chords to indicate events such as program or volume changes.
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.
Automatically reduces acoustic feedback and allows for an increase in the stable gain while minimizing artifacts for music and tonal input signals.
Monitors noise levels independently in 128 individual bands and employs advanced psychoacoustic models to provide user comfort.
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.
The narrow-band noise stimulus feature can be used for in-situ validation of the hearing aid fitting. The frequency, level and duration of the stimuli are individually adjustable.

关于混合PWM / R2R DAC的改进方案
R-2R梯形的输出电阻为R，并且由于我建议将阵列中的两个电阻并联以形成R（对于2R使用单独的电阻），因此10kΩ的阵列会产生5kΩ的输出电阻。
