1. A system for detecting an emergency vehicle comprising:
a local device, having a first processor of a set of processors and a first memory of a set of memories, operatively connected to a light wave sensor and an acoustic sensor;
a dongle, having a second processor of the set of processors and a second memory of the set of memories, operatively connected to the local device;
a vehicle device, having a third processor of the set of processors and a third memory of the set of memories;
a set of instructions, resident in the set of memories that when executed by the set of processors cause the system to:
receive a set of light wave signals from the light wave sensor;
generate a light wave spectral profile from the set of light wave signals;
generate a light profile buffer from the light wave spectral profile;
receive a set of sound wave signals from the acoustic sensor;
generate a sound wave spectral profile from the set of sound wave signals;
generate a sound profile buffer from the sound wave spectral profile;
generate a light profile buffer summary from the light profile buffer;
generate a sound profile buffer summary from the sound profile buffer;
compare the light profile buffer summary, to a light emergency vehicle signature table, to determine a light emergency vehicle type;
compare the sound profile buffer summary, to a sound emergency vehicle signature table, to determine a sound emergency vehicle type; and,
display, on the vehicle device, one of a group of the light emergency vehicle type and the sound emergency vehicle type.
