You must have seen people using hearing aids (or even used yourself) to improve their hearing ability, but what about an aid that instead of boosting the sound lessens the intensity of noise reaching your ear. Definitely, sounding unusual. Developed by Designaffairs Studio, the “Ecocoon” is a reverse hearing aid that protects your ears from the maddening noise at a crowded marketplace or when driving or walking alongside a stranded city road. Switching to the high, middle or low frequencies, you can filter the harsh acoustic stimulus, while the shut off mode completely restrict outer noise or sound wherein you may hear/sense the sound of your pulse and breathing only. The Ecocoon lets the user go on a virtual retreat and calm his/her nerves to tackle further challenges.
