Proof of Concept
Increase automobile safety and driver awareness with an “alerting system”
Detect an emergency siren audio signal
Turn down the volume of the car stereo
Display an indicator symbol on the dashboard
Increase safety in conjunction with the Emergency Vehicle Safety Initiative, a partnership between the U.S. Fire Administration (USFA) and the Society of Automotive Engineers (SAE).
External EEPROM is needed to store microphone waveform data in combination with original siren waveform
Specialized microphone could be fitted, our project will be generic
Radio speaker control relay
LED, would be CAN message to instrument cluster in real car
Siren will be detected using a matched filter
Equivalent to convolution without the time reversal
Threshold the output to determine if the siren is present
Must be robust enough to work under 10% Doppler shift
