A method of acoustic tuning includes: outputting, with a first speaker among a plurality of speakers in different locations on an aircraft cabin, a first sound; detecting, with a plurality of microphones in different locations of the cabin, first reflected sounds of the first sound; outputting, with a second speaker among the plurality of speakers, a second sound; detecting, with the plurality of microphones, second reflected sounds of the second sound; comparing, with a server connected to the speakers and the microphones, the first sound and the second sound with each of the first reflected sounds and each of the second reflected sounds, respectively; and adjusting an output gain and frequency phase of each of the plurality of speakers based on the comparisons between the first sound and each of the first reflected sounds and between the second sound and each of the second reflected sounds.
