"Calmer, which has no electrical components, decreases resonance by using a tiny waveguide inside our ears that removes the effect of the Concha. By easing this resonance, Calmer dampens down the most common alert-triggering shrill noises, such as ring tones, dogs barking, tube train announcements and sirens."
