The comuoon system consists of a slim microphone and a speaker. 2. Systems with wireless microphones are also available, allowing students with hearing problems to sit at a distance from the teacher. 3. Shinichiro Nakaishi, CEO of Universal Sound Design, formerly worked for a major record company. Assigned to new business development, he did research on speakers for concert use. It was during this time that he discovered sounds that are easier to perceive for those with hearing loss. This led to development of the comuoon system. 4. The company has donated comuoon systems to schools and classes for the hearing impaired and has received many thank-you letters from students.By raising the sound pressure in medium and high frequency ranges, comuoon enhances the clarity of sounds in the ranges around the consonants, which hearing-impaired people commonly have difficulty understanding.1342
