ASTM E1007 AIIC Impact Sound Testing

On-Site Acoustic Testing performs ASTM E1007 field impact-sound testing of installed floor/ceiling assemblies, including Apparent Impact Insulation Class (AIIC) measurements.

ASTM E1007 Impact Sound Testing

ASTM E1007 measures impact sound transmission through floor/ceiling assemblies and their associated supporting structures under field conditions. A standardized tapping machine operates on the floor above while the resulting impact sound is measured in the receiving space.

AIIC characterizes the apparent impact-isolation performance of the installed floor/ceiling assembly and adjacent structure, including the effects of structure-borne flanking paths. The standard also defines additional impact-sound metrics for particular room configurations and project requirements.

Tapping Machine and Measurement Equipment

OSAT uses standardized tapping machines together with precision building-acoustics analyzers to measure the one-third-octave-band impact sound produced in the receiving room. Our current equipment supports field measurements for residential, commercial, institutional and other occupied buildings.

Flooring, Underlayments and Completed Assemblies

Field impact testing can be used to evaluate completed floor/ceiling construction, compare flooring or underlayment systems, investigate occupant complaints, document existing conditions, and verify performance against project or code criteria. Measurements can be performed on assemblies incorporating hard flooring, resilient finishes, carpet, floating floors and suspended ceilings where applicable.

Because field results include the influence of the installed structure and flanking transmission, they should not be assumed to duplicate laboratory IIC results for a nominally similar assembly.
