Many elderly people suffer from difficulty hearing due to hearing loss of sounds at high registers, but there are also great differences between individuals. Communication between a healthy listener and a hearing impaired person imposes difficulties on both parties. It then modulates the audio frequencies of the speaker’s voice to make it easier to understand what they are saying, and then outputs the audio through a highly directional speaker in order to achieve smoother communication in situations where communication may be difficult, such as classes at school or in a nursing home.
