The present invention relates to a separated type hearing aid. The separated type hearing aid includes: a wireless earphone; and a transmission body which transmits sound to the wireless earphone through a wireless transmission antenna by processing the sound which is inputted through a microphone. The transmission body includes: a fitting mode selection key which selects a fitting mode for adjusting a gain for each frequency range which fits a user; an operation unit in which a confirmation key is arranged to generate a confirmation signal about the suitability of hearing; a beep sound control unit which controls the band and amplification level of a beep sound which is generated in a beep sound generating unit according to the control signals; an equalizer which adjusts and outputs a transmission object sound according to the gain adjusting value of each set band; and a transmission control unit which makes a beep sound, which is amplified according to the set steps as much as the amount of an amplification which is set depending on the band set in the beep generating unit, transmitted to the wireless earphone if the fitting mode is set through the operation unit, stores the corresponding amplification value in a memory according to bands if a hearing confirmation signal is received from the confirmation key, and processes a signal which is less than 100 Hz to be removed while processing sound received through a microphone by adjusting the sound according to the bands depending on the amplification value of each band stored in the memory if an infra-wave removal mode selection key is selected when in the hearing mode. The separated type hearing aid is able to remove an influence on infra-wave noise by removing a signal which is less than 100 Hz and providing sound through the wireless earphone when selecting the infra-wave removal mode selection key. |
