, the audio signal output from the handset is input to an A/D converter a that converts it into a digital signal, and is also connected to a 4-wire switching system, and the audio signal output from the 4-wire switching system to the receiver is converted into a digital signal. input to A/D converter b, which converts said A
/D converters a and b output signals are synchronized, the output signal of the A/D converter a is multiplied by n and added to the signal output from the A/D converter b, and the output signal is converted into an analog signal. It has a means for converting, a means for inputting the value of n, and a means for controlling, and by changing the value of n, the sidetone size can be freely changed to obtain the sidetone size that is most audible. A sidetone adjustment device that is characterized by the following:
