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.

Assessment:

• 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
• ASTM E1375: Test Method for Measuring Inter-Zone Attenuation of Furniture Panels Used as Acoustic Barriers
