	abstract = {We estimate a vehicle{\textquoteright}s speed, its wheelbase length, and tire track length by jointly estimating its acoustic wave pattern with a single passive acoustic sensor that records the vehicle{\textquoteright}s drive-by noise. The acoustic wave pattern is determined using the vehicle{\textquoteright}s speed, the Doppler shift factor, the sensor{\textquoteright}s distance to the vehicle{\textquoteright}s closest-point-of-approach, and three envelope shape (ES) components, which approximate the shape variations of the received signal{\textquoteright}s power envelope. We incorporate the parameters of the ES components along with estimates of the vehicle engine RPM, the number of cylinders, and the vehicle{\textquoteright}s initial bearing, loudness and speed to form a vehicle profile vector. This vector provides a <i>fingerprint</i> that can be used for vehicle identification and classification. We also provide possible reasons why some of the existing methods are unable to provide unbiased vehicle speed estimates using the same framework. The approach is illustrated using vehicle speed estimation and classification results obtained with field data.},

Since these are relatively tedious to acquire, they may not be acceptable for some applications. A number of studies have sought to perform simple customization of the HRTF. We propose and test a strategy for HRTF personalization, based on matching certain anthropometric ear parameters with the HRTF database, and the incorporation of a low-frequency "head-and-torso" model. We present preliminary tests aimed at evaluation of this customization. Results show that the approach improves both the accuracy of the localization and subjective perception of the virtual auditory scene.},
