Architectural Acoustics

ACI provides expert advice for various architectural acoustic projects dealing with reduction of sound transmission from space to space and control of noise within specific spaces.



  • Sound Transmission Class (STC)
  • Impact Insulation Class (IIC)
  • Reverberation Time (RT)
  • Review of Drawings and Calculations
  • Sound intensity measurements for flanking identification


Standards and Guidelines:

  • ASTM E336:  Measurement of Airborne Sound Insulation in Buildings (STC)
  • ASTM E1007:  Tapping Machine Impact Sound Transmission Through Floor-Ceiling Assemblies (IIC)
  • ASTM E966:  Standard Guide for Field Measurements of Airborne Sound Attenuation of Building Facade and Facade Elements
  • ASTM E90:  Standard Test Method for Laboratory Measurement of Airborne Sound Transmission Loss of Building Partitions and Elements
  • ASTM E1414:  Test Method for Airborne Sound Attenuation Between Rooms Sharing a Common Ceiling Plenum
