一般人在睡眠之後，肌肉的張力就會降低，導致呼吸道的狹窄，當氣流經過狹窄的呼吸道就會產生氣音，進而導致鼾聲的產生。近年來減少鼾聲且直接的方法就是以醫師診斷進行手術切除部位，但其中醫師所考量的是手術切除相關部位是否正確，及術後鼾聲聲壓是否有所明顯改善亦或頻率高低，都是在手術前必須詳加探討的。因此本研究將針對國內人口BMI值與鼾聲聲壓和發聲頻率及發聲部位間的相關性，及鼾聲聲壓經過頭影效應影響睡眠拍檔的睡眠感受之關連性探討。研究結果發現，軟顎之鼾聲平均聲壓級音強為36.58 dBSPL，會厭之鼾聲平均聲壓級音強為23.49 dBSPL，舌根之鼾聲平均聲壓級音強為16.3 dBSPL。個案BMI值與軟顎、會厭、舌根部位鼾聲聲壓之關聯性分析分別為P=0.49、0.29、0.84，由此結果可知鼾聲聲壓與BMI值並無顯著關聯。測量睡眠位置之頭影效應結果後發現鼾聲源於90度位置時差異最大頭影效應為3.67 dBSPL。近耳耳廓遮蔽效應部分，發現音源於105度時，音強差異為3.43 dBSPL。遠耳耳廓遮蔽效應差異最大之角度為105度，音強差異為2.78 dBSPL。將聲壓級鼾聲強度轉換為聽力級鼾聲強度，其結果軟顎鼾聲強度成為16.63 dBHL；會厭部位鼾聲強度為16.24 dBHL；舌根部位之鼾聲強度為10.79 dBHL。

When people fall asleep, the airway would become narrow due to the reduction of muscle tension, and then the snoring would occur when the air passed through the narrow airway. In recent years, the uvulapalatopharyngoplasty was the most common treatment for reducing snoring. However, the accurate part for surgery and the improvement in snoring for patients after surgery should be considered at pre-op. Thus, the correlation between the BMI value and the snoring sound frequency of snoring part would be discussed in this study. The sleep partner’s perception of sleep affected by snoring sound pressure level with head shadow effect would also be discussed. Based on the results, the mean sound pressure level of snoring was 36.58 dBSPL by palate, 23.49 dBSPL by epiglottic and 16.3 dBSPL by tongue, respectively. Based on the correlation analysis for the BMI value and the snoring sound frequency of snoring part, the p-value was 0.49 for palate, 0.29 for epiglottic and 0.84 for tongue, respectively. There was no significant correlation between the BMI value and the sound pressure level of snoring. Based on the results of head shadow effect for sleeping place measurement, the significant difference of sound pressure level was 3.67 dB at 90 degrees of snoring sound source. As for the pinna shadow effect for the near ear, the difference of sound pressure level was 3.43 dB at 105 degrees of sound source. The difference of sound pressure level was 2.78 dB at 105 degrees of sound source for the far ear. After transferring the sound pressure level of snoring to the hearing level of snoring, the snoring sound pressure level was 16.63 dBHL for palate, 16.24 dBHL for epiglottic and 10.79 dBHL for tongue, respectively.
