The invention relates to the technical field of acoustic resistance material testing, and particularly relates to an acoustic resistance material test auxiliary system which comprises a distance adjusting device, a supporting device and a sound absorption cotton adjusting sliding rod. The distance adjusting device comprises an adjusting rod slideway, a coarse adjusting sliding rod, a fine adjusting knob and a fine adjusting rod. The coarse adjusting sliding rod is installed in the adjusting rod slideway and fixed through locking screws, the coarse adjusting sliding rod is connected with the fine adjusting knob, the fine adjusting knob rotates around the coarse adjusting sliding rod, and the fine adjusting knob is in threaded connection with the fine adjusting rod; the sound absorption cotton adjusting sliding rod is installed in a tail end sound blocking pipe and is coaxial with the fine adjusting rod, and a ruler is arranged on the sound absorption cotton adjusting sliding rod. Accurate feeding is achieved through the combined action of wide-range coarse adjustment feeding of the coarse adjusting sliding rod and small-range accurate feeding of the fine adjusting rod, the testing precision is improved and the testing efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of acoustic resistance material testing, in particular to an auxiliary system for testing acoustic resistance materials. Background technique [0002] The acoustic resistance material tester is an instrument used to test the acoustic properties of materials, and plays an important role in the analysis of acoustic materials. Acoustic material testing can be used to characterize material-related uses, obtain specific material properties, test and evaluate manufacturing quality, and this information can be used for teaching. The basic properties of materials that generally need to be measured are: sound absorption coefficient, complex reflection coefficient, complex impedance, complex admittance, sound insulation loss and sound transmission loss. These material properties can basically be realized by the acoustic resistance test system. [0003] Most of the existing acoustic resistance material testing device...
