PITTSBURGH -- November 28, 2012

Akustica, Inc., a Bosch Group company developing MEMS microphones, today
announced a complete analog and digital family of top- and bottom-port high
definition (HD) voice microphones for smartphones, tablets and other consumer
electronics. The high 63dB signal-to-noise ratio (SNR), super wideband
frequency response, and tightly matched +/-2dB sensitivity of the microphones
support the growing trend in the mobile device market to utilize
higher-performance audio components along with noise-processing algorithms to
deliver HD voice quality in mobile devices.

Akustica’s new microphones are also drop-in replacements for today’s most
commonly used MEMS microphones, providing a straightforward path for
manufacturers to upgrade current designs to meet market demand for more
natural-sounding conversation and improved speech recognition accuracy that is
achieved through HD voice-quality components. The latest additions to Bosch’s
extensive consumer MEMS portfolio, the microphones are also manufactured by
Bosch, thus leveraging the high-volume capability, quality and reliability of
the world’s top MEMS sensor supplier.

HD Voice Performance, Design Flexibility

Part-to-part consistency is particularly important to achieve HD voice quality
for end users. Multi-microphone noise suppression algorithms rely on
well-matched acoustic characteristics among the microphones for optimized
performance. All four of Akustica’s new microphones deliver the same high SNR,
flat frequency response and matched sensitivity, giving manufacturers the
freedom to select the microphone with the most convenient mechanical and
electrical configuration for their device design — without sacrificing HD
voice performance. Pin-for-pin compatibility with the most popular form
factors used in today’s mobile devices helps to simplify the upgrade to
better-sounding systems.

“There is a groundswell of support behind HD voice from wireless carriers,
mobile chipset suppliers and mobile-device manufacturers,” said Davin Yuknis,
vice president, sales and marketing, Akustica. “That’s because the HD voice
experience mirrors the emotional nuance of a conversation to the point where
you feel as if you are talking face-to-face and not over a phone.”

“And sound quality is determined at the microphone, the first component in the
audio chain,” added Yuknis. “If the noise is too high or the microphone cuts
off important voice-band frequencies right at the start, that performance
cannot be recovered downstream.”

The Bosch Advantage for Akustica Customers

With more than 20 years of MEMS production experience, Bosch is the industry’s
only company to design and manufacture its consumer and automotive MEMS chips
entirely in-house. This approach provides advantages to customers. While other
consumer MEMS suppliers are often forced to purchase their MEMS chips from
third-party suppliers to speed time to market, Bosch leverages its in-house
technology and expertise in MEMS design, development and manufacturing to
quickly introduce innovative new products. Bosch’s rapidly expanding consumer
MEMS portfolio is a case in point. It includes microphones from Akustica and
inertial, magnetic and pressure sensors, as well as sensor-fusion software,
from Bosch Sensortec, another Bosch Group company.

“Bosch supplies MEMS sensors to nearly all of the world’s top-tier auto
manufacturers — an industry that essentially demands zero defects and a
continuous supply of components,” said Klaus Meder, president of the
Automotive Electronics division, Robert Bosch GmbH. ”Similarly, Bosch extends
its extremely high-quality standards throughout all of its product lines,
regardless of the market being served. Consumer-electronics manufacturers that
use Akustica HD voice MEMS microphones benefit from the integration ease and
flexibility delivered by these new microphones as well as reap the rewards of
working with a high-quality and high-volume supplier like Bosch.”

Market Growth for Microphones

According to Jérémie Bouchaud, director and principal analyst for MEMS &
Sensors at IHS, the worldwide MEMS microphone market is expected to grow to
more than 4 billion units by 2016, as compared to the 700 million shipped in
2010. The reason, he said, is that the number of microphones used in each
smartphone has already gone from one to two and in some cases even three — a
number that may continue to grow while mobile device manufacturers use sound
input quality as a differentiating feature.

“With a market this large, there is not only room for many suppliers, but
multiple suppliers are often required by the biggest MEMS microphone
purchasers,” said Bouchaud. “This represents a tremendous opportunity for
reliable, high-volume MEMS microphone suppliers to provide the full portfolio
of microphones needed by their customers.”
