<p>A sound processing apparatus includes a first calculator (130R) that calculates a first power based on a first signal received by a first microphone (110R); a second calculator (130L) that calculates a second power based on a second signal received by a second microphone (110L); a gain calculator (140) that calculates a gain on the basis of the ratio of the first power to the second power; and a multiplier (160) that processes the second signal using the gain calculated by the gain calculator.
