Disclosed is an IC chip type hearing aid module for use in a mobile
communication terminal having a hearing aid circuit including: a first
section having a resistor R1 and an inductor L1 which are connected in
series on a first output line Receiver_P between the mobile communication
terminal and an ear speaker; a second section having a resistor R4 and an
inductor L2 which are connected in series on a second output line
Receiver_N between the mobile communication terminal and the ear speaker;
a third section having a resistor R2 and a capacitor C2 which are
connected in series between an input terminal of the first section and an
output terminal of the second section; and a fourth section having a
resistor R3 and a capacitor C3 which are connected in series between an
input terminal of the second section and an output terminal of the first
section.
