Abstract
The acoustic waveform that is of interest in the processing described in this chapter is obtained by recording the noise from a vehicle under normal operating conditions; it is a complex signal in which the characteristics of the engine, the exhaust system, the bodywork, and the environment are all intermingled. This is shown diagrammatically in Fig. 13.1 from which it can be seen that the task of classifying vehicle noises requires the selection from the total waveform of that part of the information relevant to the particular classification required. Two tasks that are of interest are:
-
1.
The “recognition” between different types of vehicles (e.g., rollers and wheeled, petrol and diesel, etc.).
-
2.
The “identification” of a particular engine in a variety of environments, compared with other engines also in different bodyworks and environments.
