A digital hearing aid processor (DHAP) chip built around a general-pur
pose 16 bit DSP core is presented. The designed DHAP performs a nonlin
ear loudness correction of eight frequency bands based on acoustic mea
surements. The DHAP provides all the flexibility needed to implement a
udiological algorithms. Ln addition, the chip has a low power feature
and 5,500 x 5,000 mu m(2) dimensions that make it suitable for wearabl
e hearing aids.
