Acoustic laboratory is a special acoustic environment created by people, which is mainly used for acoustic research and environmental acoustics research. Sinosteel National Inspection can not only go to the site to do acoustic experiments, but also acoustic laboratories can do experiments, the center now has two functional laboratories: reverberation laboratory and sound insulation laboratory. At the same time, it is also equipped with a team of acoustic talents and high-end acoustic devices to provide customers with high-quality acoustic testing services.
