How loud is 130 cfm?

CFM, or cubic feet per minute, measures airflow and does not directly correlate to sound level. To assess loudness, you would need to consider the decibel (dB) rating of the device producing that airflow. Typically, the noise level generated by equipment with a specific CFM rating can vary widely based on design and technology. For example, a fan with a high CFM may produce anywhere from 30 dB (whispering) to 70 dB (normal conversation) or more, depending on its efficiency and construction.
