Scientific Breakthrough in Sweden May Help with Loud Snoring
The model found loudest snoring comes from unsteady airflow across soft tissues, and researchers say it could guide future palatal stiffening treatments.
- Researchers from the KTH Royal Institute in Stockholm, Sweden, developed a 3D model simulating upper airway airflow and tissue movement to understand the physical mechanics behind snoring, as published in the journal Physics of Fluids.
- Study author Peng Li noted that "many existing studies simplify breathing or neglect the interaction between airflow, tissue motion, and sound generation," which hinders understanding of how breathing drives snoring. This knowledge gap motivated the research effort.
- Simulations revealed that the loudest sounds resulted from unsteady airflow across the soft tissues of the mouth, specifically the soft palate vibrating during breathing. This finding identified the dominant sound generation mechanism.
- Li said "reducing soft palate vibration or unsteady aerodynamic loading may help reduce palatal snoring," potentially informing evaluation of stiffening procedures and other tissue-modifying interventions. The findings offer a pathway toward treatment development.
- Future work will investigate how palatal stiffness affects vibration and resulting snoring sound, Li said, aiming to identify mechanical conditions that could clarify how stiffening treatments reduce palatal snoring. Researchers plan to expand simulations to incorporate treatment effects.

Snoring may seem like a simple nocturnal nuisance, especially for those who share dormitory with the person who does, but behind that sound there is a complex physical phenomenon that science still tries to fully understand. Now, researchers at the Royal Institute of Technology KTH in Sweden have developed a three-dimensional model of upper airways that has allowed them to study how air and soft tissues interact during snoring. Their results poi…
A Swedish team of researchers has developed an advanced computational model to understand why some people emit such strong sounds when breathing while sleeping.
Scientists develop a more palatable approach to treating snoring
A new three-dimensional computer model is offering scientists a closer look at one of the most familiar—and frustrating—sounds in human sleep: the rumble of ordinary snoring. Researchers at the KTH Royal Institute of Technology in Sweden have simulated how air moves through the upper airway, how soft tissues respond to that airflow, and how their […]
