This paper describes an acoustic strain effect of a multimode optic-fiber sensor. The transmitted coherent light wave through a multimode fiber produces a complex speckle pattern. This pattern is analyzed with the method of modal interference. The speckle pattern changes with the acoustic phase modulation of the modes. The light intensity has been measured. An experimental system of this sensor has been built up. The spectrum of the acoustic effect has been obtained.
