Abstract:
Objective To investigate the relationship between sound pressure level parameters of snoring sound and obstructive sites in patients with media or severe obstructive sleep apnea hypopnea syndrome(OSAHS). Methods Forty-six patients with media or severe OSAHS were included in this study.All underwent continuous upper airway pressure measurements and snoring sound pressure level recording simultaneously.The correlations between obstructive site,AHI,BMI and sound pressure level parameterssuch as equivalent continuous sound level (LAeq )and maximum sound pressure level (L10 )were analyzed.Results Both LAeq and L10 were affected only by AHI,whereas unrelated to obstructive site and BMI.Conclusion There is no definite relationship between the site of obstruction and sound pressure level parameters of snoring sound.It appears that LAeqand L10may be helpful to e-valuate the severity of OSAHS,but may have no clinical value on distinguishing obstructive sites.
