THE PROBLEM
Snoring is often dismissed as an inconvenience. For the person beside it, the real cost is what the sound takes away: uninterrupted sleep.
of surveyed US adults with a bed partner said that partner snores. [3]
of additional sleep per night was the estimated equivalent for partners after snoring and obstructive breathing were eliminated in a small overnight study. [4]
One bad night is an annoyance. Night after night, partner snoring can turn repeated interruptions into a pattern of insufficient sleep. The concern is not the sound itself. It is the sleep you keep missing.
Chronic short sleep is linked to obesity, diabetes, high blood pressure, heart disease, stroke, anxiety and depression. [5] In one long-term cohort, people sleeping six hours or less in midlife were 30% more likely to later develop dementia. [6]
Undertone is designed to break that chain. Reduce the disruptive sound at your ears, without asking either partner to leave the bed.
THE SOLUTION

Record on your phone at home. We identify the frequencies that recur in your partner’s snoring, from low rumbles to sharper sounds.
A hearing professional checks your ears and takes an impression or scan. We include the appointment in the price. [1]
Your ear shape sets the fit. Your partner’s recordings guide the sound configuration. We bring them together in soft, low-profile earplugs made for sleep.

WHAT GOES FURTHER
A low rumble and a sharp rasp put different demands on an earplug. Published research shows that snores vary in their frequency patterns. [2] Undertone uses your recordings to guide the choice of configuration, giving the sound that bothers you a say in the design. The research supports that rationale; Undertone’s matching benefit is still being tested.
No. Passive earplugs reduce sound; they do not remove it completely. How much you hear depends on the sound, the fit and how the plugs sit while you sleep.
A good fit starts with your actual ears. A professional checks the ear canal and captures its shape for your pair. That examination and impression process is described in British Society of Audiology guidance. [1] A current impression may also make ordering your next pair easier.
Yes, we’ll happily accommodate an upgrade. If your saved impression or scan is still suitable, we can use it to make your Signature pair without another fitting appointment. We’ll check your fit file before making the new pair.
No. Undertone is for the listening partner’s comfort. Earplugs do not treat sleep apnea or replace prescribed treatment.
