title: [Characteristics of sleep in deafness].
abstract: INTRODUCTION, MATERIAL AND METHODS: We studied a profoundly deaf population, in order to evaluate the zeitgeber sleep role of the ambient sound. A closed questionnaire was given to 36 students at a special college for the profoundly deaf and to 321 controls of similar age and sex.
  
  
  RESULTS
  We do not find total upset of sleep, but a good sleep quality, probably due to the noise isolation of the deafness. We find some traces of insecurity in falling asleep.
  
  
  CONCLUSIONS
  The ambient sound do not seem to play an important role as a sleep-wake zeitgeber.
