In addition, they will enhance autonomous driving features …

and even allow interaction from outside of the vehicle

– Event sound detection / sirens detection / contact detection

– Road condition detection

Contributing to road safety, as they can be employed to pick up

sounds like sirens from emergency vehicles or to detect dangerous

road conditions thanks their large dynamic range and acoustic

overload point

Voice recognition / external interaction

Allowing external interaction e.g. for controlling certain

functions via voice commands due to their good suitability for

voice recognition use cases

Customer benefit

› Automotive qualification according to AEC-Q103, together with long term availability reduces design-in risk and effort

› Increased operating temperature range allows flexible usage in automotive environment up to +105°C

› Best in class audio performance (SNR, AOP, THD) for optimum speech quality and capture of distortion-free audio signals

in loud environments as they can occur inside a car

› Narrow sensitivity matching for enhanced performance of beam-forming (noise suppression) arrays

› Flat frequency and stable phase response for optimal fit in acoustic noise cancellation use cases
