|1. (WO2018201252) AUDIO PROCESSING FOR VEHICLE SENSORY SYSTEMS|
ESFAHANY, Siamak Akhlaghi
|Title:||AUDIO PROCESSING FOR VEHICLE SENSORY SYSTEMS|
Audio-derived information is provided to a vehicle control system of a vehicle by attaching a microphone externally to a vehicle to generate an analog signal in response to sound waves external to the vehicle. An enclosure containing sound-attenuating material mechanically filters low frequency sounds from reaching the microphone transducer. An analog-to-digital converter converts the analog signal to a digital signal. A vehicle data bus transfers the digital signal to the vehicle control system.
