product Audina Hearing Instruments, Longwood, Fla, introduces the Instinct digital line of hearing instruments. The Instinct is a 16-band, 4-channel WDRC product with adaptive phase cancellation feedback management and adaptive noise reduction. The noise reduction algorithm is designed to minimize distortion and applies attenuation only to the bands in which the noise predominates thus maximizing gain for the patient. Concurrently, the feedback cancellation system continuously and adaptively self-adjusts for varying conditions in the feedback pathway, which cancels the feedback without gain reduction.
