Thiết bị hiệu chuẩn độ ồn BSWA CA925 High Pressure Microphone Calibrator
Because there are so many high sound pressure environments in the fields of national defense and aerospace, the research of high sound pressure is more and more important in modern science. In order to carry out these studies, there are many high sound pressure microphones, whose maximum sound pressure level often reach or exceed 170 dB. How to verify whether they can really reach the declared target sound pressure level, and measure the linearity and distortion has become a new topic.
