Paper Title :
Active Design of Exhaust Sound

Author :Wen-Kung Tseng

Article Citation :Wen-Kung Tseng , (2020 ) " Active Design of Exhaust Sound " , International Journal of Mechanical and Production Engineering (IJMPE) , pp. 16-19, Volume-8,Issue-5

Abstract : Exhaust sound is one of the most important part in car. It also represents the car performance. The sound quality is very important for the exhaust sound. Exhaust sound from a car cannot be changed after manufacture. Therefore this study investigates the performance of active sound design for modulating the original exhaust sound to the desired exhaust sound. The basic principle of this is to make use of one or two microphones to acquire the original exhaust sound. Then the exhaust sound is fed into the controller which calculates the optimal signal for the input to the secondary source. The secondary source produces the optimal sound to modulate the original exhaust sound to the desired exhaust sound. The results showed that the exhaust sound of VW Lupo could be modulated to that of Audi A1. Keywords - Exhaust sound, Car Performance, Microphones, Controller, Secondary Source.
