Abstract: The present invention relates to a method for preparing a sound-adsorbing material and a sound-adsorbing material. The method includes the following steps: S1, preparing a non-foaming material slurry and mixing the slurry uniformly; S2, forming the non-foaming material slurry by using an oil column forming method to form wet granules; S3, drying the wet granules to form dry granules; and S4, roasting the dry granules to form sound-adsorbing material granules. The method has the advantages of simple operation and high reliability. The formed granules can have a uniform size, a smooth surface and high sphericity, and the granules are in contact with each other in points and piled up uniformly, which can reduce the bed resistance.
