Sj. Quinn et al., THE DIFFERENTIATION OF SNORING MECHANISMS USING SOUND ANALYSIS, Clinical otolaryngology and allied sciences, 21(2), 1996, pp. 119-123
Ten subjects known to suffer from heavy snoring but not obstructive sl
eep apnoea were studied using the technique of sleep nasendoscopy. The
mechanism of snoring was noted for each and sound recordings of the s
noring noise were made. Six subjects were observed to snore using thei
r soft palate only, three snored using only their tongue base and one
snored using a combination of palate and tongue base. The sound record
ings were subjected to computer analysis of waveform and frequency. Pa
latal flutter snoring and tongue base snoring appear to have distinct
waveform and frequency patterns which allows them to be differentiated
from each other.
