Significance of fan noise test

Ensure the health and safety of human beings and the environment, and improve the performance and efficiency of the fan. Fan noise is caused by airflow and mechanical vibration when the fan rotates. If the noise level exceeds the specified standard or environmental noise level, it may have a negative impact on people's health and life. The noise test of fan is helpful to determine the noise level of fan and provide useful information for improving and optimizing the design of fan. The test can guide engineers to use better materials and technology in the design and manufacture of fans to reduce the noise level. In addition, the test can also help to monitor the performance and working conditions of fans and ensure that they are within the normal working range.
