Abstract
This study delves into how the equalizer can compensate for a sound pressure of lost frequencies. The targeted audiences are senior citizens who have difficulties hearing high-frequency because of a decline of audio frequency. Through investigations, this study confirms that the reason why reduction of high-frequency hearing increases depending on senescence. By considering the features of audio frequency of senior citizens, it also clarifies the necessity of equalizer reflecting features of audio frequency for the senior citizens, which have dramatically increased in Korea. There are application programs having functions, which provide several options of equalizer setup that people can adjust it depending on their own audio frequency. Some of them provide different equalizer setup depending on age. This study, however, reveals that they are not fully enough to compensate for the range of hearing loss of the senior citizens. Therefore, by pointing out limitations of existing functions and suggesting improvements, this study explores the way of improvements that enhance the sound transmissions of digital media contents for senior citizens.
