ACUPRO Measurement System

With SPECTRONICS' ACUPRO Measurement System, you can evaluate the sound absorption of acoustical materials quickly and accurately.  Conforms to standards ISO 10534-2 and ASTM E-1050 using the two-microphone method.

"One tube - One sample - One measurement"


  • Uses standard ½ or ¼ inch microphones
  • 100 W driver allows testing over a wide range of sound levels
  • Made of dense, highly damped materials to minimize excitation by internal sound
  • High wall TL allows testing in high-noise environments
  • Low ambient internal noise

Other Applications

  • Measurement of transmission loss of materials, mufflers, and silencers
  • Signal-to-noise measurements below ambient conditions
  • Phase calibration of microphones for sound intensity measurements
  • Frequency response checks of microphones and systems
