Abstract

Regarding Senile Hearing Hardness: Of those who purchased hearing aid in 2003 90% were elderly people older than 60 years. It has been estimated in Japan that 25% of the population will be above 65 years old a decade later and that the ratio would go up still higher after that. In other words, the elderly increases its importance. This means that society requires activity of the elderly. For the elderly to take an active part in society, positive measures of communication are essential.
