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.
Massive and robust - three times more dense than other impedance tubes and many times more rigid, the ACUPRO impedance tube minimizes excitation of the tube structure by even very high sound levels in excess of 130 dB. Thick walls of highly damped materials block sound from entering even in high ambient sound environments.
