Research on Sound Source Material Recognition Technology in Indoor Geotechnical Inspection

Abstract: Studies have shown that physical parameters such as size have obvious influence and relevance on the sound spectrum structure. In order to study the new detection technology of sound recognition of compaction of soil, this article conducted a large number of indoor soil sample hammering tests. The timbre features of the sound are extracted by the impact sound feature extraction method based on the principle of auditory perception, and the focus is on the correlation between frequency domain eigenvalues such as… Show more
