And such snoring high or low sound is accompanied by the severity of the abnormality of the upper airway, snoring people breathe hard, chest breathing is harder than normal people, and the negative pressure generated by excessive chest force causes the airway to close, and the medically diagnosed apnea occurs. Family members or people in the same room often hear the snoring stop and then make a louder sound. This snoring brings many hazards to people.
