Snoring can be measured by placing a microphone on the neck.

Alternatively, it can be calculated from nasal pressure, since higher flow rates and greater force on vibrating structures produce lower-frequency pressure changes.

Currently, neither of these methods has been validated as an objective means of measuring snoring.
