title: [The influence factors of sound pressure level parameters in patients with simple snoring and obstructive sleep apnea hypopnea syndrom].
abstract: OBJECTIVE
  To discuss the main influence factors of sound pressure level parameters in patients with simple snoring (SS) and obstructive sleep apnea hypopnea syndrom (OSAHS).
  
  
  METHODS
  Eighty-four cases with snoring disease underwent polysomnography and simultaneously snoring sound pressure level recording. The correlations between AHI, age, BMI, abdomen circumference, neck circumference, the lowest oxygen saturation total apnea time and sound pressure level parameters: equivalent continuous sound level(LAeq)and maximum sound pressure level(L10) were analyzed.
  
  
  RESULTS
  LAeq was significantly correlated to AHI (P= 0. 000) and BMI (P= 0. 007), and the odd ratios of AHI and BMI were 5. 74,2. 09 respectively, but it was unrelated to age, abdomen circumference, neck circumference, the lowest oxygen saturation and total apnea time. A significantly association also existed between L10 and AHI(P=0. 000), BMI(P=0. 032), and the odd ratios were 4. 11 and 2. 33 respectively. Other factors had nothing to do with L10.
  
  
  CONCLUSIONS
  The main factors which affect the snoring sound pressure level parameters LAeq and L10 are AHI and BMI.
