Digital Electronic processing starts with the digitization of the sound signal. The digital sound signals are then analyzed, filtered, amplified, optimized and re-synthesized by digital signal processing (DSP) chips.

Digital Mechanical Processing (DMP) starts with the digitization of the shape of the ear. Using the latest laser scanning methods Phonak is now able to produce a perfect, three-dimensional replica of the ear impression taken by the hearingcare professional.

The digitized image of the ear is also analyzed, filtered and treated by dedicated software. In this way, an optimized virtual shell is created.

Next, a laser beam is guided to physically build the ITE shell. The shell is produced by solidifying polymer powder with the laser’s light. Finally, shell assembly and the integration of the electronics combine the precision of computer aided design tools with the skill of experienced Phonak technicians.
