摘要： PURPOSE:To realize an audio reproducing device capable of being shared by people having difficulty in hearing without defects of information by compressing wide band voice signals into the audible frequency range left to the people having difficulty in hearing with a range compression technique before outputting. CONSTITUTION:A audio information input section 1 converts sound wave information such as a microphone, into the corresponding electric signals with a sound-electricity converter 11 to input the information into a frequency band compression section 2 through an amplifier 12. The frequency band compression section 2 performs frequency conversion of the input audio signal with a band compressor 21 according to a compression rate set in a compression setup technique 22. The compression rate may be fixed for a particular person having difficulty in hearing, while the value may be variable by the user. Audio signals compressed in a defined band are then entered to a frequency characteristic adjusting section 3, where the amount of adjustment for each frequency and the total shape of the characteristic curve are adjusted to be set to an audio information output section 4.
