SAN JOSE, Calif.–(BUSINESS WIRE)–Nov. 3, 2016– InvenSense, a leading provider of MEMS sensor platforms, and Sonion, the global leader in micro acoustic and micro mechanical technologies and solutions for hearing instruments, in-ear earphones, and specialty headsets, today announced the release of the O-series MEMS microphone in 2 very small form factors: O8 (8mm³) and O11 (11mm³). The new O-series, which has been designed specifically for hearing aids, provides superior sound quality with a very high signal-to-noise ratio (SNR), increased overload margin for extended dynamic range, and very low power optimized for 0.9V operation. The O-series products offer hearing aid manufacturers greater flexibility in hearing aid design.

The O-series, which will begin to ship in volume in January 2017, is designed to meet the stringent directionality requirements of hearing aids. In Sonion’s dedicated manufacturing facilities, the O series microphone sensitivity is precisely trimmed to the required sensitivity. This tight sensitivity distribution eliminates the need for sensitivity calibration between two microphones in a hearing aid. Combining this with the low-humidity drift and long-term stability of the O-series MEMS microphone enables a perfectly stable directional system. With this groundbreaking performance, the O-series sets a new standard for MEMS Microphones for hearing aids and is expected to be the microphone of choice for future designs.

“Our continued collaboration with Sonion is key to InvenSense’s strategy of bringing our micromechanical technologies and solutions for hearing instruments to market,” said Behrooz Abdi, president, and CEO, InvenSense. “As a leading provider of Sound solutions for consumer electronic and industrial applications, InvenSense is committed to partnership with Sonion to develop technology to meet the stringent requirements of the Hearing Aid industry.”

“By adding this next generation of MEMS microphones to our already very strong electret microphone portfolio, we exemplify our commitment to provide customers with the broadest range of products for the hearing aid market,” said Jørn Mørkeberg, CEO, Sonion.
