Widex was one of the first companies to offer digital signal processing hearing aids. Their circuits have proven to be very popular with our customers over the years, even with the increased competition presently on the market (some offices sell over 16 different brands and models of dsp hearing aids, and the number keeps increasing).
Since Widex first introduced the Senso, they have added models including ones with directional microphones, telephone coils (for non-CIC models), power circuits for severe hearing losses, a non-automatic model with a volume control (P series), and BTE models in colors (beige, brown, gray, red, yellow, blue, green, and black).
They also released the Senso Plus™ circuit. The Senso Plus uses the same basic digital signal processing ideas, but adds several new features. To refresh your memory, the basic Senso has three independent channels for sound processing, uses time domain processing to disquingish speech from noise, selectively reduces noise signals, has automatic feedback control, and is completely automatic in operation.
