As the population ages, where there is an increase of hearing-impaired people due to aging, communication issues end up growing at homes, hospitals and government offices each year. Traditionally, a hearing-impaired person would normally use a hearing aid to improve their hearing. COMUOON is a table-top conversation support device, which enables a moderate hearing-impaired person with 70db hearing loss to improve their hearing without wearing a hearing aid, by creating sound that is easy for a hearing-impaired person to hear from the speaker's side. The gentle and stylish cocoon-shaped design fits into any space by incorporating simple design into the operation panel, while securing the directivity of the sound.
