A study on active noise cancellation earmuff

    Graphical Abstract
    • Abstract
  • In this paper a compound active noise cancellation earmnff combining the close loop feedbackcontrol method and the open loop feedforward control method is proposed and the formula representing the principle of noise cancellation as well as the stucture are given.This compound active noisecancellation structure features a wide concellation band and an excellent cancellation effect.
