Sound Synthesis for an Engine Air Induction System

Sound Quality is one of the most important factors to achieve a successful design for Engine Air Induction Systems. Vehicle and bench testing, and simulation tools can be used in order to optimize and refine emitted noise. One difficulty on using simulation in advanced development phases is the necessity to interpret the response curves and assess if sound quality is acceptable. One recent and promising area to help simulation interpretation is the sound synthesis of the emitted noise. This paper presents a simple procedure and example with the objective of reproducing the emitted noise, which allows subjective assessments of different tuning concepts. The example, even a simple one, shows the advantage to finally hear what was simulated.
