Transmission Parameters of Porous Sound Absorbers (with Particular Reference to the Flow Resistance)Nature (1963)
Flow resistance, being relatively easy to measure, is commonly used as a rough guide in choosing sound absorbing materials for specific purposes. This practice is based on the tacit assumption that, when there is an alternating air-flow through the sample, the resistance encountered is identical with the flow resistance. It can be shown, however, that in the case of several materials this assumption is false, an that the acoustical resistance under alternating condition is substantially greater than the flow resistance.
