Dspfactory's Toccata Plus chosen by Otologics for fully-implantable digital
hearing device

WATERLOO, ON, April 04, 2003 -- Dspfactory Ltd., a leading provider of
programmable digital signal processing (DSP) technology for hearing aids,
headsets, PDAs, and other portable devices, today announced that its
Toccata Plus platform has been selected by Otologics LLC for use in its
next-generation MET Ossicular Stimulator, a fully-implantable middle ear
prosthesis. The device is scheduled for launch early next year.

The MET is for the treatment of severe hearing loss and consists of a tiny
transducer implanted directly into the middle ear space near the eardrum.
The processing power of Dspfactory's Toccata Plus chip will enable the MET
to be customized to each patient's hearing loss profile through the use of
sophisticated digital sound processing algorithms.

"Our device is fully implanted into the user's ear and it was essential for
us to select a customizable digital platform that is very small and
light-weight, and which delivers the computational capabilities we need
while enabling extended battery life," said Scott Miller, Otologics'
Implant Project Manager. "Toccata Plus was the clear choice. We've been
using Dspfactory technology through our development process and in our
semi-implantable MET device and we've been very pleased with the
performance of Toccata Plus."

Toccata Plus is Dspfactory's software-configurable digital audio chip that
is specifically designed for use in hearing aids. It combines exceptional
audio performance with ultra-low power consumption -- all within the
compact design demanded by today's ultra-miniature devices.

"The Otologics MET is an impressive showcase for the flexibility and power
of Toccata Plus," said Geoff Bellew, Dspfactory's vice president of sales
and marketing. "It's a leading-edge device which, because it is surgically
implanted, places significant restraints on the size and power use of its
components, and this is an environment where Toccata Plus truly excels.
We're delighted by Otologics' continued endorsement of our platform."

Toccata Plus is easily customized for a broad range of hearing devices and
lowers the cost of design, manufacturing and inventory for device
manufacturers while shortening development cycles and reducing
time-to-market for new devices. It combines digital/analog signal
conversions and advanced digital signal processing on a single 0.18-micron
chip and features a tightly-integrated system-on-a-chip (SoC) design that
delivers the processing power needed to implement advanced algorithms on
even the most compact hearing instruments.

About Otologics
