Flare Calmer What are the most annoying sounds you can think of? Nails scratching down a chalkboard? Car alarms? It could be that our ears, through thousands of years of evolution, are sort of designed to find these sounds particularly unpleasant to act as a warning that danger is imminent. That’s great for our ancient ancestors, listening out for prowling sabre-tooth tigers, but for us modern humans it’s just plain annoying. In fact, according to audio specialists Flare, the shape of the eardrum itself acts as a bell, adding 20db of distortion-causing resonance. This irritating distortion could impact on our mental and physical wellbeing, so the idea behind the Flare Calmer earplugs is that they change the shape of the eardrum to cut out the particularly annoying distorted frequencies between 2,000-8,000 Hz. By doing this, they claim to reduce ear fatigue, noise-induced headaches and overall stress levels. So does it work? Well, it’s hard to tell how much earplugs can reduce you...
