1. A sound processing apparatus, comprising:
a microphone configured to collect surrounding sound;
circuitry configured to:
receive gain control information from a specific device, wherein the gain control information is determined by the specific device based on location information of the specific device and audio setting information of the specific device;
produce a noise reduced signal at a first specific frequency band based on the surrounding sound and the received gain control information;
produce a surround sound listening signal based on the surrounding sound; and
generate a combined sound signal based on:
addition of the noise reduced signal and the surround sound listening signal, and
control of each of a gain of the noise reduced signal and a gain of the surround sound listening signal based on the received gain control information; and
a speaker configured to output a sound based on the combined sound signal.
