The soundproof room is to isolate the outdoor noise source, so that the indoor environment is relatively quiet and meets the requirements. The sound insulation room is composed of standard components such as door panels, windows, wall panels, top panels, and sound-absorbing ducts. The sound insulation room is mainly used for hearing testing in hospitals, schools, scientific research institutions and other units, and industrial and mining enterprises as equipment control rooms. The sound insulation rooms produced by our company are mainly divided into seven specifications, and the sound insulation capacity is divided into two levels of 30~35 and 40~45dB(A). Various types of sound insulation rooms can also be customized according to user requirements.
