SleepNoise

It is well known that sleepiness is an important contributor to crashes. The drivers are influenced by circadian low, hours slept or being awake. There is also reason to believe that variations in interior road noise may be a contributing factor. Up to now the road noise models in simulators are not very mature and not validated.

The aim of the technical part of the SleepNoise project was to develop the road noise model for the ViP simulation infrastructure, including individual vehicle types driving on individual road types. The goal was a sound model, close enough to the original real world setting as to be approved by vehicle noise experts. The resulting modelled interior sound spectrum should not deviate more than a few decibels from the corresponding recorded sound.
