Abstract
Sleep at the wheel is responsible for about 30% of road traffic deaths in the country, according to ABS (Brazilian Sleep Association). When correlating the cerebral behavior during stages of sleep initiation and acoustics in the vehicular environment, the present study raised the hypothesis that an induced sleepiness can occur by the noise inside the automobiles, being this one, triggered by pink noise soundwaves. In this context, this work aims to analyze aspects between sleepiness at the wheel and traffic accidents, the applicability of clinical pink noise for sleep induction and to compare it with the vehicle interior sound in order to classify it, or not, as a pink noise. Applying techniques of signal processing for the data acquired and after graphical comparison by spectrograms, it is concluded that the sound recorded inside the car evaluated during long road trips confirms its classification as pink noise.
