| description | The invention relates to a sound signal processing apparatus (100) for enhancing a sound signal from a target source. The sound signal processing apparatus (100) comprises a plurality of microphones (101a-f), wherein each microphone (101a-f) is configured to receive the sound signal from the target source; an estimator (103) configured to estimate a first power measure on the basis of the sound signal from the target source received by a first microphone (101a-f) of the plurality of microphones (101a-f) and a second power measure on the basis of the sound signal from the target source received by at least a second microphone (101a-f) of the plurality of microphones (101a-f), which is located more distant from the target source than the first microphone (101a-f), wherein the estimator (103) is further configured to determine a gain factor on the basis of a ratio between the second power measure and the first power measure; and an amplifier (105) configured to apply the gain factor to the sound signal from the target source received by the first microphone (101a-f).
