Determination of a Sound Level for Railroad Horn Regulatory Compliance

Confidence regions for level sets

This paper discusses a universal approach to the construction of confidence regions for level sets {h(x) ≥ 0} ⊂ Rd of a function h of interest. The proposed construction is based on a plug-in estimate of the level sets using an appropriate estimate �hn of h. The approach provides finite sample upper and lower confidence limits. This leads to generic conditions under which the constructed confid...

Modeling road traffic noise using distributions for vehicle sound power level

Research evidence suggests that annoyance, sleep disturbance and other health effects of road traffic noise exposure may be related to the level and number of noise events caused by traffic as well as to energy equivalent measures of exposure. Because measurements show that the variation in noise emission between vehicles within the same category can be considerable, it is essential that the in...

Spectral Modeling for Higher-level Sound Transformations

When designing audio effects for music processing, we are always aiming at providing higherlevel representations that may somehow fill in the gap between the signal processing world and the end-user. Spectral models in general, and the Sinusoidal plus Residual model in particular, can sometimes offer ways to implement such schemes.
