1. A sleep induction device comprising:
a speaker configured to output sound;
a sensor configured to obtain a breathing signal of a user; and
a processor configured to:
obtain a breathing frequency of the user per a first time period based on the obtained breathing signal;
determine and generate a breathing-tuned sound according to a characteristic frequency by combining a breathing induction signal with an ambient noise masking sound, wherein the characteristic frequency of the breathing-tuned sound including the ambient noise masking sound is determined according to a characteristic of the breathing induction signal; and
output the breathing-tuned sound for inducing sleep in the user by inducing the user's breathing while simultaneously reducing the ambient noise,
wherein the characteristic of the breathing induction signal corresponds to a magnitude of the obtained breathing signal or a frequency of the obtained breathing signal for a second time period.
