Driving Simulator; Engine Sounds
"Simulating a driving environment that provides engine sound as auditory feedback to the driver is a challenging task due to the complexity of engine sound, a wide range of operating speeds, and repeated sound clicking during playback. This thesis describes a method of engine sound simulation and generation for a driving simulator. By analyzing sample sounds, spectral modeling synthesis was used to decompose the sound samples into deterministic and stochastic components. Then, the modeled deterministic and stochastic signals were employed to resynthesize the sounds. To represent engine sounds not available in the recorded database, sound interpolation was applied to two neighboring engine sounds. In addition, a cancelation method was developed to remove the repeated clicking that occurs when engine sounds are played in a loop. Finally, a powertrain model was used to calculate the engine speed. As seen by comparing the spectrograms of the sounds, the resynthesized sounds exhibited high similarity to the recorded sample sounds. Also, the spectrogram of the sound generated by interpolating two sample sounds was found to agree fairly well with the actual engine sound"--Abstract, page iii.
