Abstract:
A first sound detection unit is installed in a predetermined member forming a vehicle so as to detect solid vibration of the member and convert the solid vibration into an electrical sound signal. A second sound detection unit detects vibration of air inside the vehicle and converts the vibration into an electrical sound signal. A data recording unit records at least one of the sound signal detected by the first sound detection unit and the sound signal detected by the second sound detection unit in a recording medium. The sound signal detected by the first detection unit and recorded in the recording medium is corrected by using the sound signal detected by the second sound detection unit, or the sound signal detected by the second detection unit and recorded in the recording medium is corrected by using the sound signal detected by the first detection unit.

Claim (Index 3):
The driving information recording device according to  claim 2 , wherein\n the signal processing unit comprises: a first adaptive filter that generates a response signal by filtering the sound signal detected by the second sound detection unit; a first subtraction unit that subtracts the response signal generated by the first adaptive filter from the sound signal detected by the first sound detection unit and outputs a resultant signal; a second adaptive filter that generates a response signal by filtering the sound signal detected by the first sound detection unit; and a second subtraction unit that subtracts the response signal generated by the second adaptive filter from the sound signal detected by the second sound detection unit and outputs a resultant signal, wherein the first adaptive filter modifies a filter coefficient in accordance with an error signal output from the first subtraction unit, and the second adaptive filter modifies a filter coefficient in accordance with an error signal output from the second subtraction unit.
