This paper presents some results of a method aimed at extracting instantaneous engine speed information from acoustic emission measurements obtained from Formula 1 (F1) vehicles during a race. The results presented in the paper show that it is possible to reconstruct the instantaneous engine speed for an entire race, if desired, from available sound intensity measurements. The analysis method used in this work is applied to acoustic emission data recorded by the microphone of the in-car cameras mounted on F1 vehicles. The data analyzed in this paper were acquired during the 1998 Grand Prix of San Marino (Imola), and pertain to the performance of the Ferrari and McLaren-Mercedes vehicles. At the time of writing the paper, these are the two teams challenging one another for the driver and constructor championships.
