The air flow resistance is a fundamental acoustic parameter to understanding the properties of cellulose based insulation material, it is useful for research and development to perform acoustic performance prediction and for calculation modelling. There is a connection between structure of cellulose based insulation material and its acoustic characteristics. Specific air flow resistance is also a parameter for the quality of cellulose based insulation which is used for factory production control because there is also strong connection between specific air flow resistance and density of produced material. Experimental measurement of airflow resistance has been performed according to the direct method of the EN 29053 standard where low and constant air flow is passed through cellulose based insulation with a specific section.
