With the ACUPRO Measurement System, you can evaluate sound absorption of, and the transmission loss associated with, materials quickly and accurately. Conforms to standards ISO10534-2, ASTM E-1050 and ASTM E-261.
The optional transmission loss (TL) tube couples to the impedance tube to allow TL measurements of soft and flexible barrier materials using the ASTM 2611 procedure. The ACUPRO software may also be used in conjunction with the TL tube to measure the TL of mufflers.
