Engine Speed Tracking and Reference Generation for Active Noise Profiling

Research output: Chapter in Book/Report/Conference proceedingConference article in proceedingsScientificpeer-review

Abstract

Active Noise Profiling (ANP) is special type of Active Noise Control. In ANP, the periodic noise components are attenuated or enhanced to modify the audible psychoacoustic profile of the target. Such components may be the engine orders in a car, for example. To create required reference anti-orders artificially, the quality of the engine speed tracking is an important factor of the ANP. The engine tracking is usually done with direct tachometer sensor or via a vehicle data bus. A comparison of both tracking methods is done, and a practical implementation of an engine speed reader is presented. Also, the model of the reference generation and its real-world counterpart are presented. The limitations and shortcomings are discussed. They include reading latencies and accuracy issues. The developed system is well suited to practical applications, and its properties can be further fine-tuned with the extensive model of the speed detection and reference generation parts.
