Calmer benefits everyone by reducing unnecessary stress caused by everyday noise. Noise-sensitive people often notice the effect immediately, whereas others may need to wear Calmer for 5-10 minutes in a noisy setting and then remove them to appreciate the stress reduction that Calmer is delivering.

Calmer is a hollow, soft silicone ear tool that upgrades our ears to reduce ear resonance. Calmer is not an earplug; it does not block or muffle sound which means you don’t experience the occlusion that is common with all earplugs.

You can use Calmer anywhere there’s noise and still communicate comfortably. The technology is designed to become part of your everyday routine to reduce unwanted stress from daily sound.

Calmer can be used anywhere to reduce our stress response to noise whilst still being able to communicate effortlessly. Typical places to wear Calmer: Public transport, busy streets, noisy offices, restaurants and bars.

According to The World Health Organisation (WHO), environmental noise is the second biggest killer after air pollution. They highlight that just a 10dB increase in daily traffic noise exposure leads to a significant increase in heart attack, obesity and stroke because it creates additional stress on our bodies due to the increased release of the stress hormone cortisol.

Following 18 years of research in sound, we have discovered that noise is not the only problem - the shape of our ears also has a significant impact. Our ears are shell-like shapes that have evolved to increase stress response to sound by resonating sound at frequencies between 2kHz – 8kHz. This resonance triggers the release of cortisol. Whilst the effects of HRTF have been known and studied for some time, we are the first to realise that our ear shape plays a role in the release of cortisol and have developed unique technology to address the issue.

Behind the tragus in our ears there is a small shell-like shape which causes sound to resonate as it enters. Our patented technology alters the geometry of this area so that instead of sound bouncing around the shell resonating, it reflects of a flat surface which reduces this resonance. Because the technology is simply improving sound reflection, there is no sound reduction or muffling.
