HIGH PERFORMANCE PORTABLE SHIELDED LOW FREQUENCY NOISE MEASUREMENT EQUIPMENT

摘要

The present invention relates to low frequency noise measurement equipment composed of shielding plates (10v, 10h) for shielding outside noise, which is installed with test equipment and objects to test, and is equipped with a shielding chamber (10). A honeycomb band (20) to allow inside air to circulate with outside air but block an introduction of the outside noise may be further installed at a sidewall of the shielding chamber (10), so the overheating of the objects to test inside the equipment can be prevented by circulating the inside air. A moving wheel (13) is installed on the bottom to facilitate the moving of the equipment to a desired place.
