Abstract
A process device and system for measuring flow parameters in flowing gases is provided in which a device for flow-induced sound generation is in the area of the flow to be measured. A measurement of the frequency and/or the level of the sounds generated is made during the flow to be measured as acoustic parameters. A determination is made as to the flow parameters to be measured by processing the measured acoustic parameters. The process makes possible, in particular, the measurement of the volume flows during respiration near the patient.
