First bio-inspired directional MEMS microphone unveiled

30 August 2022

Soundskrit has introduced what it claims is the first bio-inspired directional microelectromechanical systems (MEMS) microphone designed to bring high quality audio to current and future connected consumer devices.

Called the SKR0400, the MEMS microphone integrates a new transducer design for maximum audio performance and combines proprietary software for a wide range of devices and use cases. These include:

  • Laptops
  • Smart speakers
  • Smart TVs
  • Headsets and earbuds
  • Augmented/virtual reality
  • Healthcare engineering
  • Wearables
  • Connected vehicles

The MEMS microphone eliminates unwanted noise at the hardware level with a highly directional pickup pattern that filters background noise and reverberation from audio, isolating a user’s voice with high-fidelity. The sensor eliminates the need for large omnidirectional microphone arrays for small, low power and lightweight solutions for improved performance. Minimal signal processing enables noise and echo reduction, true stereo recording for audio content and voice tracking.

Bio-inspired

“We needed to create something small and directional, so we took inspiration from the smallest auditory systems in nature,” said Stephane Leahy, vice president of hardware and co-founder of Soundskrit. “We’ve created a microphone that truly isolates a speaker’s voice and delivers the highest-quality sound. We’re not stopping at just one microphone, Soundskrit is building and engineering audio for the future.”

The audio sensor technology reimagines sound capture based on how insects process sound versus humans, Soundskrit said. Smaller auditory systems in nature such as insects all use a different method to sense sound. Insects respond to air flow rather than pressure.

The MEMS microphone transducer was designed to improve directional microphones. By moving in sync with the surrounding air motion, the transducer can accurately sense an incoming sound wave and convert it into a high-quality electronic signal.
