Norsonic NOR1517A Test Systems

Discover the Norsonic NOR1517A Test Systems — engineered for precise, standards-compliant acoustic measurements. Applications Quality control in production process. Testing in research and development About The quantity airflow resistance is one of the most important parameters for the description of porous materials with strong links to its acoustic properties. A low value for the airflow resistance indicates little resistance for air streaming through the material and a high value indicates that the material is closer to air-tight. Nor1517A measures the specific airflow resistance – and related quantities – by the applying the alternating airflow method according to ISO 9053-2:2020 Acoustics – Determinations of airflow resistance – Part 2: Alternating airflow method. The Nor1517A system is based on the dynamic principle. An AC motor driven piston produces a oscillating movement causing an alternating air-flow of frequency 2Hz into a cylindrical tank and through the test material. The pressure modulation inside the cylinder is measured by a condenser microphone connected to a sound analyser using the 2Hz 1/3 octave band on the sound level meter Nor140. The specific airflow resistivity results are calculated in an Excel spreadsheet or alternatively read from the meter directly in Pa s/m The measurement results may also be stored in the instrument memory for further use/documentation.
