Characteristic Evaluation of Impact Sound Reduction by Floor Coverings Using Floor Impact Sound in a Test Building

Abstract:

Impact sound reduction under various conditions for a total of eight different types of Floor cosverings currently used in South Korea. The results of floor impact sound within the test building under bare slab conditions indicated a high reduction rate for lightweight impact sound, but poor reduction during heavyweight impact sound testing (Bang Machine, Impact Ball). However, a reduction was identified in the mid-high frequency range (315 Hz–3150 Hz) for the lightweight impact sound, as was a reduction of approximately 2 dB–3 dB at specific frequency ranges, depending on the thickness of the floor coverings, for the heavyweight impact sound on the Ondol structure.
