Abstract: An acoustic filter for shielding noise and an ITE(In-The-Ear)-typed hearing protectors applied by the same are provided to prevent the hardness of hearing by inserting various kinds of acoustic filters and changing the position of the film. An acoustic filter(10) for shielding noise is composed of a first acoustic pipe(12) having a cross-sectional area(S1); and a second acoustic pipe(14) having a length(L) and a cross-sectional area(S2) connected with the first acoustic pipe in series. The acoustic energy transfer property is changed by controlling the ratio of the cross-sectional areas and the length. The diameter of the acoustic filter is obtained by controlling a diameter(D1) of the first acoustic pipe and a diameter(D2) of the second acoustic pipe to correspond to the property of the sound transfer band desired within the maximum 6mm. A maximum length(Lt) is obtained by controlling the length of the second acoustic pipe to correspond to the property of the sound transfer band desired within the maximum 10mm after setting the maximum length.
