R3710-CEAA-E1 Description

RHYTHM� R3710 is a preconfigured DSP system designedspecifically for Invisible−In−Canal (IIC) hearing aid devices.Available in the industry’s smallest hybrid form−factors, it is wellsuited for hearing aid designs that are placed deep in the ear canal.Using miniaturized advanced packaging techniques,ON Semiconductor enables hearing aid manufacturers to takeadvantage of the highly compact size to produce IIC hearing aids thatfit a greater portion of the market. Featuring iSceneDetect�environmental classification, adaptive noise reduction, feedbackcancellation, and up to 8−channel WDRC, R3710 provides theadvanced features and performance level typically found in high−endproducts.Acoustic Environment Classification − The iSceneDetectenvironmental classification algorithm is capable of analyzing thehearing aid user’s acoustic environment and automatically optimizesthe hearing aid to maximize comfort and audibility.iLog� 6.0 Datalogging − Enables the recording of various hearingaid parameters such as program selection, volume setting and ambientsound levels. The sampling interval can be configured to record fromevery 4 seconds up to once every 60 minutes. The fitting system canpresent the data to help the fitting specialist fine tune the hearing aidand counsel the wearer during follow up visits.Evoke� Advanced Acoustic Indicators − Allows manufacturersto provide more pleasing, multi−frequency tones simulating musicalnotes or chords to indicate events such as program or volume changes.Adaptive Feedback Canceller − Automatically reduces acousticfeedback and allows for an increase in the stable gain whileminimizing artifacts for music and tonal input signals.Adaptive Noise Reduction − The adaptive noise reductionalgorithm on R3710 monitors noise levels independently in 128individual bands and employs advanced psychoacoustic models toprovide user comfort.Tinnitus Masking − R3710 is equipped with a noise source that canbe used to mask tinnitus. The noise can be shaped, attenuated, and dutycycled then summed into the audio path either before or after thevolume control.In−situ Tone and Noise Generator − The narrow−band noise andtone stimulus feature can be used for in−situ validation of the hearingaid fitting. The frequency, level and duration of the stimuli areindividually adjustable.www.onsemi.com
