AB  - Uncertain speed of sound will lead that the interval perturbation method fails to
      precisely predict the uncertain acoustic field in some frequency bands. An
      uncertainty reduction technique is proposed for this problem. This technique
      first determines the bands in which the interval method is being invalid through 
      the modal frequency analysis. Then, the dimensionality of the uncertain
      parameters is reduced by converting the uncertain speed of sound into a certain
      one. This technique can be used in the interval or subinterval perturbation
      methods. The numerical example demonstrates that the proposed technique is
      effective for uncertain acoustic field simulation with interval parameters.
