What is snoring? If you share a bedroom with a snoring partner (or pet!), chances are you already know what snoring is. For the blissfully unaware, snoring is the sound made by vibrations in the soft palate and tissues of the mouth, nose and throat. When the upper airway is partially blocked, this sound is amplified to varying degrees. The British Snoring & Sleep Apnea Association estimates that at least 41.5% of the adult population snore, which equates to around 15 million people.
