Ten subjects known to suffer from heavy snoring but not obstructive sleep apnoea were studied using the technique of sleep nasendoscopy. The mechanism of snoring was noted for each and sound recordings of the snoring noise were made. Six subjects were observed to snore using their soft palate only, three snored using only their tongue base and one snored using a combination of palate and tongue base. The sound recordings were subjected to computer analysis of waveform and frequency. Palatal flutter snoring and tongue base snoring appear to have distinct waveform and frequency patterns which allows them to be differentiated from each other.
采用睡眠鼻内镜检查技术对10名已知患有严重打鼾但无阻塞性睡眠呼吸暂停的受试者进行了研究。记录了每名受试者的打鼾机制，并对打鼾声音进行了录音。观察到6名受试者仅通过软腭打鼾，3名受试者仅通过舌根打鼾，1名受试者通过软腭和舌根组合打鼾。对录音进行了波形和频率的计算机分析。腭部扑动性打鼾和舌根打鼾似乎具有不同的波形和频率模式，这使得它们能够相互区分。
